  2. Well that was a most enjoyable comp with more rounds than I think any of us would have expected! Big thanks to Joel for organising. Looking forward to the next one, in the meantime some photos: https://rc-soar.smugmug.com/F3F/2022/WWL4/

  3. Well, what a surprise that was. Can't believe I'm getting better at reading the forecast so it must have been that the 11 pilots asked for the same thing for Christmas Anyway, as Dave said, after a slight delay due to the haze and lack of wind we finally got going just before 12 and then walloped off 9 rounds in constantly building air. I have to say, the standard of flying was fantastic and the conditions and small field meant it felt quite gladiatorial as different pilots stepped up to put a marker down. Anyway big thanks to all those who attended, as everyone did their bit. I'll post the results ASAP

  4. Well that was unexpected.11 pilots took the bait of a possible comp. From 12pm after clag cleared we had 9 great rounds in very consistent conditions. All in all a great day. Well done to the top 3. Top 6 pilots scored 970 or above!! Happy with my 5th place. Last round was interesting. Thumb slipped off elevator stick half way round turn 4!! Thanks to Joel and Graeme for running the show

  7. Yesterday the first batch of CN Sensors arrived in the UK. I was very keen to have a close look at these models and compare them with some of the other F5j models currently available. When unpacking two things were immediately apparent - 1) the quality and surface finish of the wings is possibly the best I have seen out of handling lots of models from quite a number of different manufacturers and 2) The attention to detail is truly outstanding and definitely the best I have seen. Other things apparent when unpacking were the very thin airfoil and general level of completeness and pre-fabrication. The latter was expected as the Flightech price of £1750 includes a full factory IDS and fuselage install. Just add servos, motor etc and it is ready to go. Basic parts count. Four piece wing, two piece fuselage, rudder, tailplane. Plus a very complete accessories pack. Initially when 4 piece wings started to come on the market I thought it a bit gimmicky. After now owning four piece wing models I think it is a great idea, and when combined with a two piece fuselage it really helps pack the models away into a much smaller box. For example CN models kindly made me box measuring only 130cm x 30cm x 30cm and I can fit three 4m Eternity models in it. Flightech Sensors all come with pre-fitted CNC machined alloy motor mounts Servos are mounted in the top of the boom. All will come with factory installed servo trays, linkages and a really superb MPX plug system that automatically engages with its opposite side in the front fuselage. I really love this feature and it made me smile when I first saw it.Note slot at front edge - this automatically engages in a molded in carbon spiggot in the front fuselage to stop tail rotation. Plug holder is molded in carbon. Really nice. The internals of the rear portion of the front fuselage. You can clearly see the mpx plug. The white disc is the end of the fuselage mounted ballast tube. T This is what greets you when you take off the canopy - rudder and elevator servo plugs. Not so clear but just visible if you look closely is the carbon ballast tube. With the servos in the tail boom there is plenty of room for motor, esc and battery. Tail boom showing rudder mounting system and pre-installed rudder pushrod. Needless to say the fit of the rudder is perfect. The elevator linkage system. I liked the specially molded elevator horn with molded in ball joint. However I know from a lot of the Ospreys sold (which has the same type of pushrod system) the fiddly 2mm screws used to bolt the horn onto the tail are not too popular with people so as with the Ospreys this is something that might want modding to the Samba type tube and wire system. I personally don't mind it as it helps the tailplanes pack down nice and flat without anything sticking out. A shot of the fuselage. The wing is four piece as mentioned, but rather than being plug on like the Eternity and Explorer Q the Sensor features a bolt on centre panel. The 2 panels are joined together in the middle with a main central carbon joiner and then this is then bolted on with 4 bolts (2 bolts per panel). Seems to work well. The bottom of each centre panel has a MPX plug for wing servo connection. In the fuselage are two rectangular cut-outs for the fuselage side MPX connectors. The fuselage plugs appear to be floating and not permanently mounted which is fine but I am sure could be made self-engaging if wanted. Flightech Sensors all come factory fitted with carbon rudder horns that link up with an L bend in the rudder pushrod. Looking now at the wings, as previously mentioned these are possibly the nicest quality I have seen so far from any manufacturer. I have yet to see (thank goodness) how ding resistant they are but they but they feel similar to wings from Samba so pretty good. Again, we have tried to go for completeness so Flightech Sensors all come fitted with Servorahmen IDS foam mounts. And very nicely they have been fitted. You can see in the pic below how crisp and neat everything is. On the top surface it is clear CN have used the larger heavier duty IDS linkages with 1.4mm pins. This is very wise as although not huge flaps as found on the Explorer Q and Hawk, the Sensor can be considered to have pretty large control surfaces. Certainly when compared to the Prestige. Of particular note is the molded in recess if you wanted to use stick on gap seal tape. This is a nice feature if using gap seal tape. Personally I don't think they make any real difference but your mileage may vary. Looking at the tip panels, what is not immediately obvious is that the ailerons are top hinged. This is very different indeed and quite a departure from most commercially available molded models from the last 15 years or so. It certainly allows for plenty of free up going travel if large control movements are your thing. It has been done because the wing section is just so thin the aileron horns need all the help they can get with creating a long enough moment arm to make the geometry work. To this end, the Sensor comes with small carbon aileron horns (like pictured on the rudder) and the linkage comes out of the bottom skin. I will show more about this later on. You will note on this one no aileron servo frames are fitted. This is only because the Servorahmen IDS frame that fits the Kingmax C507 needs slight modification as it is intended for the KST X08. So I will be doing this mod myself for the customer. But as we speak there are already loads of foam mounts i have already modified on their way out to CN models so they will be fitting them at the factory. Not the most exciting pic below, but as all Flightech Sensors normally come with fully fitted IDS frames here is a chance to see the servo pocket. Note the neat CNC cut channels already cut in the rohacell core for the servo wires. This is nice attention to detail. Also apparent in this shot is the beautiful crisp neat molding quality. Very thin Stefan Eder / Max Steidle airfoils are used. As with many of these new type of airfoils (perhaps not all) it promises better ability to move around the sky at much lighter weights and penetrate better in wind. We will have to see with the Sensor but so far reports are very good. Root section.. Tip section.. And that pretty much wraps up the first look at the CN Models Sensor. I am sure you can now appreciate my opening comments about the overall quality and especially the attention to detail of these new F5j models.

  15. Its just over 2 days until 2021. I hope you all had a great Christmas. By consensus, the rules for the 2021 F3L/F5-RES challenge will be: ------------------------------ This is a for fun challenge for UK based pilots, anyone may enter with EITHER 1. a bungee-launched glider up to 2 metres wingspan and the standard Hi-Start can post a time. The standard Hi-Start bungee is a maximum of 10m of 6/4mm surgical tubing and 50m of static line (minimum 30lb breaking strain). Lighter/smaller bungee rubber may be used. OR 2. an Electric motor launched glider up to 2 metre wingspan fitted with an Altitude Limiter set to 60m and a maximum motor run time of 20 seconds. Object: Fly your 2 metre wingspan glider for as long as possible from a flat field. The challenge will commence on the 1st day of the Calendar month and the person who's time is unbeaten at the end of the Calendar Month 'wins' and a new challenge will start. The challenge will end on the 31st December 2022. Rules: Flight times begin when the line releases from the tow-hook or in the case of an electric motor powered glider, 20 seconds after the hand launch. The model must land in the launch field for times to count. While the object is to encourage F3L/F5-RES types, any model up to 2 metre span may be flown (F3L/F5-RES, foam, R/E mouldie) but please state the type of model when you submit your time. Note that ailerons or other camber changing devices fitted are no longer permitted, even if disabled. Scoring flights must be submitted within 24 hours of the flight taking place. All scoring flights must start with a hand release from Ground Level with (if applicable), the motor running. No Flight information telemetry permitted except for Received signal strength and Receiver battery status. Submitted scores will be amalgamated into a league. Points will be awarded as follows: 1st -15 points, 2nd - 12points, 3rd - 10points, 4th to 12th, 9 to 1 point respectively. The top 7 scoring flights to count. In the event of a tie, the 8th scoring flight will be taken into consideration and so on. Fly safely! No slope soaring --------------------- Please let me know if that is not clear enough. Have a great New Year

I was so impressed with it I had new parts made for the F3B model and also ordered an F3F version. It is ready to be maidened. Still waiting for suitable weather and wind direction....

  22. Non geared, but 28mm diameter. The motor I would chose is a 2208-1400kv (which is 28mm) - unavailable anywhere in the world. So I have to use a 1000kv - so have to run only 50W, but it gets me there with zoom. Heavier models on 2212-1400kv (superb). Rx = Multiplex Rx ...... Rx-5 Light - Only one aerial, but sub 5g if you remove the case. If you want a better Rx then Rx-6-DR Light which is then 11g but 2 aerials. Then you could go "propper" Rx's but they are over 25g (sad face). Using a "Park flyer" Rx bothers me a little, I prefer one aerial out of each side. Having said that - I have never had any problems, but you don't go up and away with the lift like you would with a 4m model. With a 28mm motor, you need a hole ~34mm........ Then add the balsa on the outside (3mm) and you are using a 40mm spinner. I have gone with the motor turned round and just sticking out -- but I have filled them with mud a few times, Then they get the hose pipe ! Putting it in can be fun !

  24. I like to fly a lot and so 600g was always my lower limit. A bungee launch puts far more stress on an airframe than electric (by a mile). If you just take a bungee glider and add a motor, you cannot have it right. Buiding very light has not been a problem, except weeds puncturing the ProFilm Lite (3 times). There are no brakes - but in very light conditions, no problem......... It will spin well.

  26. Sat : misty start, cold, wet, muddy, grey but around 6mph winds. Lost the wing bolt on my X-RES so no F3-RES flights. Dad not able to fly anymore so gifted me his Fantasia 100" and Andreas F5-RES. Still on his old hi-tec kit at the moment but had some reasonable flights and one decent climb out with the Andreas. Perishing cold. Sun : misty start, wet and muddy, but forecast was for sun later. Wind 7-10mph. Great advert for F5-RES models! Wasted the first hour with the bungee, the braided line had slipped off the winder and ended up in a knotted mess. That's now in the bin. Resorted to the old back up white bungee but that couldn't get much over 30 meters so that is also now in the bin. Ended up cobbling together the 7 meter tan tubing and the old static fishing line. With the wind direction, the length was inch perfect for the width of the field on full stretch. Was able to launch to just under 60 meters. Sun started to break through but the wind was increasing. 2nd launch I got away but rapidly disappeared downwind, managed to slowly creep up wind without losing too much height, picked up some more lift and followed that back at a decent rate of climb. Tried to push forward again but model was starting to drift backwards. I got a bit greedy and circled in more lift but went even further downwind. Started to lean on the elevator to push forward, thinking 15-20 mins was on the cards. Suddenly like a light switch the wind increased to 12-15mph! I stuck with it thinking it was only temporary but turned out it was like that for the rest of the afternoon. I was in full speed mode, losing a lot of height and not exactly speeding forward. Ballast would have been useful at this point. I made it over the hedge with a few feet to spare, narrowly missed sticking it in a tree and made the field by about 2 meters!! Not my finest moment but I was pleased with the flight given the less-than-ideal conditions. Surprisingly good lift for January. I switched to the DLG for first time in a long time and had some good climb outs with it. It penetrates like a rocket compared to the X-RES. High pressure for this coming week, hopefully it lasts until next weekend. X-RES | 16th Jan | 13m 5seconds

  34. Sorry for the late post. As usual, the forecasts haven't been particularly helpful with some predicting low cloud and some suggesting variable wind conditions. Anyway, as of this morning, I think there is a fair chance of getting a comp in with the mountain forecast suggesting 15-25 mph and cloud base lifting so I'm going to call it ON with 2 caveats. 1) I get 10 people to agree to travel 2) 1 of those 10 will bring the key to the gate (currently in the Midlands, I think) Could you please post below if you plan to attend.

  39. Not done any posts for a while as so busy with things sorry. A lot of the time has been spent putting models together for people - yes Flightech now offers a build service £100 inc. frames for wings and £150 inc frames for complete models. And it is proving popular with customers with a fair few models put together for people by me but I have now enlisted two very trusted and high quality experienced builders to help ease the workload and more importantly improve delivery times on builds. With a couple of the beautiful new 3.98m Hawk Sparks already sold and out there, this was the first time I was asked to put one together for someone. This time just the wings which suited me fine because the fuselage looks straightforward and a lot easier than the likes of Prestige, Eternity etc but I was keen to see how the unique Hawk factory installed IDS system was to fit out and how it works in practice. With thanks to Keith Fisher however, who has put together a Hawk for himself I can share some installation pics of a completed fuselage to give you an idea.. Okay then we'll start on the fuselage. The Hawk fuselage leaves you very little to do. The rudder comes pre-fitted with a metal horn that engages into an L-bend made in the pushrod. So nothing to do to on the rudder. The elevator comes with a small piano wire horn that engages into a tube already installed for the elevator pushrod so nothing to do on the elevator either. The wiring loom and wing-fuse plugs are already made up and installed at the factory so no wiring loom to do either.. The Hawk comes with a complete accessory pack that looks to have everything you need for the fuselage. There is a carbon servo tray and carbon motor mount included. The tray is CNC cut for 12mm servos and accepts the popular Kingmax CLS2035HHV perfectly. Installation is nice and straightforward and very familiar and conventional. The only thing Keith notes is good planning of the servo / battery locations is essential to get the recommended CG depending on what motor and battery type you are using. As you can see the fuselage is still relatively slim but has plenty of room for the gear and a nice big canopy to help ease all the bits in and give easy access. You can see Keith has used 12mm Kingmax servos on rudder and elevator. And so to the wings. As mentioned the Hawk comes with its own unique IDS system pre-installed. It features very nicely molded carbon pushrods terminating in a piano wire L-bend at the servo end. They are extremely stiff both vertically and horizontally which is of course great news. Vertically it means the large big flap control surfaces should remain firm and rigid. Horizontally it means the L-bends should never come as they feel like stiff and spring like. So how to link up that L-bend to the servo? Two options.... 1) Use either normal servorahmen frames or the bearing frames and use conventional servo horns. Keith did this and found the aileron horns needed drilling a bit closer to the hubs to get them under the servo cover. For the flaps Keith chose to use metal control horns and these proved slightly proud of the bottom surface and needed a small blister.. 2) Use a Servorahmen IDS system but modify it to accommodate the L-bend rather than the normal servorahmen IDS method. I chose this route. First job is to modify the servo arms. You need to cut the side off nearest the bearing to allow the L-bend to slide into the other side unrestricted. You also need to open up the existing 1mm holes to 1.5mm (I will double check the diameter of the piano wire as I opened up the holes with a reamer not a drill bit). You also need to modify the frames somewhat. First file some width off so they fit width wise into the servo apertures (a few millimetres needed for the recommended CLS0612W/KST X10 mini size) but servos smaller than this shouldn't need any width taking off. Then you need to cut the shelf off all 4 frames and grind off a triangular section on one side to allow it to slide under the Hawk IDS pushrods. Even smaller frames will need this modification. As they say a picture is worth a thousand words.. Whilst we are on the subject of servo horns, the usual length suspects are also used on the Hawk Spark.. So with the necessary horns and frames prepped accordingly, the installation then follows your usual preferred method. One thing I quite liked was the lengths of the Hawk pushrods. To get the frames centrally located with both lug screws easily accessable without resorting to dremelling a semi-circle out of the aperture lip it required the aileron horns to rake back one tooth. This makes the aileron linkage a bit better mechanically and gives a bit of natural differential and more unrestricted up aileron movement. Here is an aileron servo horn at neutral.. Flap horns also needed my preferred horn offset and needed raking a small amount forward towards the spar to get the frames centrally located. Certainly all good so far. Getting the servos and frames into position seems best done by going in at and angle and getting the bearing side of the frames underneath the IDS pushrods (hence cutting off the shelf part and grinding off the triangular sections). Then lowering into position and sliding into place and linking up the L-bends into servo horns. Again picture worth a thousand words.. And once you do all this using your chosen method to bond the frames in Hey Presto..! One pair of aileron servos in very neatly and with plenty of servo movement needed to get the required control surface movements so as to minimise slop and maximise power and resolution. Flap servo installation notes to follow shortly.......

  45. Yes that is flying weight. I have a 400g one and this is the new lighter version. The fuz is finished, which is above. It was on the wings from the other above. I am hoping to go lighter when wings are finished. I made a case that it would be possible to build down to 310g. It is, but would get a little too expensive. The present problem being 30g of prop and spinner and 35g of motor. Also the motor mount (glass) which all adds up. Here it is with "wrong" wings...........

  47. Thanks Mike. I try and build and fly all models i sell before sale so I can pass on any helpful info to pilots or weed out any poor models or accessories which I have done. For F5j i do most of this testing but if I can't I put it out to very trusted pilots who I know will do it for me. For f3f and slope models it is exactly the same principle but with less top end competition experience on my part with these sort of models I have been working with established and notable names to help refine lay-ups etc to make sure the models available for sale are spot on and perfect for the job.

  48. Right flaps. Nothing different or special here. With IDS you are able to get enough up travel and plenty enough down travel for braking and keep the horn under the servo cover. It has occured to me I have been talking about the unique Hawk IDS system and not taken any pics of the control surface end so here you go.. As you can see it is a specially made carbon molding. It is about 1.5mm thick and of particular note 8mm width so hence the tight springiness of the L-bend. I would think this is done on purpose as everything i am coming across on the Hawk features a high level of attention to detail. With regards to the frames you need to modify them exactly as per aileron ones if you use standard size 10mm aileron servos. There will be more depth to play with but there is no advantage in tweaking accordingly. As mentioned the flap horn has to rake towards the spar to get the correct neutral which is the correct way of doing things and again proof of the right way to do it direct from the factory. Here is a pic of the flap set at neutral and the angle of the control horn set in its bearing frame ready to slide in the servo. Slide in a servo to an IDS horn i hear?!?! Read later and see how it is done... Frame bonded in place and ready to install the servo. You can see in the above pic the length of the supplied Hawk pushrod arm and the required forward angle of the servorahmen servo horn to make the flap neutral. This is perfect. You can also see the frame has been left the whole length to cater for the longer Kingmax CLS0911W / KST X10 servo size servo. This is recomended for all but lighter air builds given the size of the flaps. And with a similar installation process to the ailerons it's job done. The shorter 50mm servo leads of the Kingmax wing servos make for an easy and neat installation. Any other useful hints and tips? Well hopefully yes... 1) Fitting of tight Servorahmen IDS horns onto servo gears. For Kingmax we use the same as the KST IDS mounts as they have the same diameter and tooth count. The frames fit the servo perfectly but are a tight fit on the servo horns (they are also a tight fit on the KST gears but to a slightly lesser extent). So here's a trick....use heat! I must have passed on this on to dozens and dozens of people but don't think have ever documentated anything. Servorahmen stuff is made from an injection molded carbon plastic. Because of this it is light and extremely rigid which is perfect. It has also been designed to be tight fit on the servo output gear as any advantage gained by an IDS system can be lost with needless slop. So to overcome this it is purposely a tight fit be it KST or Kingmax So the trick is to heat the horns up before fitment. You can really heat them up quite a lot as they are pretty resistant to normal amounts of heat but what they will do is expand that tiny bit and also become a more pliable and then you will find they will notch in much better and with a bit of twist and wiggle whilst hot they will locate and push on perfectly. Once done they will then forever go on and off easily like a normal servo horn. No need for heat. What you will also find using this technique is that the servo gears will have located much better in the horn. They will notch in and push on very positively and this will prevent any stripped IDS horns in use. Any stripping of the IDS horn in normal use can generally be put down to a horn that has been poorly located on the output gear (kind of inbetween teeth) and then forced hard into position. This can mush up the splines in the IDS horns and cause them to strip if given enough provocation. It does take some messing about with and practice to hone the technique but you can have a play with the unused IDS horns left on the sprue. Definitely try to heat the horn rather than the servo! The more heat the better as far as the horn is concerned but do try and avoid too much heat getting to the servo. 2) Getting perfectly matched flap servo neutrals (geometrically) so the pushrods are an identical length
