    Infinity or Explorer?

    INFINTY EVO is a very easy to fly model . but be aware that all modern purpose designed F5J models are good . just make sure you research the right hardware for the particular model and how installation is done, as some of the latest Fuzs can be very tight fit .

    3rd 2020 2m Hi Start 14 day Duration Challenge

    Met up with StraightEdge for some RES flying yesterday. Beautiful location! Think we had everything in the air. Full size gliders, motored paragliders (also sharing the field), microlights, ultra lights, red kites, buzzards, kestrels and I believe a peregrine falcon! Windier than I was expecting and the terrain seemed to funnel the wind / infill and magnify it. Added some nose weight but at times I was either stationary or going backwards. This had the advantage that when I hit lift the model went vertically up and no need to turn Only really had 1 decent flight. A good launch and once hooked up with some lift, didn't really need to do a great deal, the air was generous to me. David | X-RES | 24:50 | 12th July StraightEdge's Pure-Res flew very nicely. Appeared more agile and better penetration compared to the X-RES. Hopefully when V-Tail properly sorted it will be back in the air. My cheapo Emax rudder servo doesn't seem very happy. Lots of backlash and twitching (spring not overly strong). Going to replace for something better. KST or Futaba probably.

    F3K and Mozzy 14-day challenges 2020

    flew from a different field yesterday, was quite a bit winder than forecast and the terrain seemed to amplify the infill. It wasn't until gone 4pm that conditions went really nice. After a full day on my feet, I opted for a bit of deck chair flying. Had a really nice flight just before 5:30pm. Flying my light NXT, had to work hard for first 15 minutes with one very low save. Then found some decent smooth lift to climb out. Very pleasant end to the day. David | expert | F3K | NXT | 28:02 | 12th July |
  5. Ah well, there’s nothing new under the sun! On p82 of Sailplanes 1920-45 Martin Simons writes of the Darmstadt D-28 Windspiel: ‘The rudder was of an ingenious double action type. The front portion of the vertical tail was not a fixed fin but moved as a rudder. To it was hinged the rear portion, geared in such a way that it moved twice as much as the front segment.’ That was in 1933, when students at Darmstadt Technical University tried to build as efficient a sailplane as they knew how. The plane held the world distance record for a short time, but was wrecked when a powered plane landed on it at Griesheim aerodrome. It was replaced by the slightly heavier D-28b, which was also a good performer. Both planes were very pretty. It is not clear from Simons’ description whether the two parts moved in concert or in opposition, although I think that the description of the gearing suggests the latter. It looks to me as if your elevator does the former. My grasp of formal aerodynamics is insufficient to analyse the issues here properly, but my intuition (always a bad guide!) tells me that an oppositional setup would induce less drag all other things being equal. Does anyone know? By the way: Congratulations on a most ingenious piece of work!

    Wow! That is amazing GuyB...small world. Yes negatives long gone now. Next time I visit mum's I'll take a better pic of that pic (in an old scrap book) if it helps. Great to hear your father Geoff carried on to full size gliders and all. I was born in 63 and have been passionate about flying/model building since very early age... going to Richmond park and having the good fortune to meet your kind father, who gave me my first go on a real radio control glider, set the passion/obsession that still haunts me to this day... Even went on a weeks full size glidding course at Long Mynd which was one of the best experiences of my life... I've been out of the rc soaring game for 30 years and have been getting back into it with renewed passion these past couple of years. Thank you Geoff for that day. Nice one GuyB

    3rd 2020 2m Hi Start 14 day Duration Challenge

    Got my re-covered PuRES maidened today. Very nice soarer with good penetration (better than the X-RES?) but discovered that (i) I hadn't configured enough mechanical movement on the V-tail control surfaces, especially the rudder side of things, which no amount of fiddling with the TX could change; and (ii) that the torsion-springs I made up aren't man enough to prevent flutter - which I experienced on launches and when flying into very active thermals or through big down-draughts, so couldn't make best use of the conditions! But Cirrus, who'd come over to join me, did much better with his own X-RES !!

    Double-vision when flying?!

    Thanks for the input Wavecloud. Interesting about the purple/red tints - especially as I've speculated that part of the problem might be the shocking pink colour of my Middle Phase against a predominantly blue/grey sky... an uncomfortable 'chromatic' contrast? I've certainly been more aware of the need to keep better hydrated of late (especially after meals) and haven't had any further recurrence - flying either thermal or smaller slope models closer in.
  15. We'll do it again tomorrow - Monday 12th July Arrive went you want, leave when you want. A few competition style slots will be run like above.
  16. An excellent day! Thank you to everyone that came and made it so. We trialled the GliderScore eScoring system and it worked very well - I barely had to use the laptop, once to correct an input error and then to see who had won. I used about 2.5Mb of my mobile internet data allowance - next to nothing. I'm looking forward to using it for a full contest soon. Randy had a problem with his model and his spare wasn't fully programmed in to his new Tx, he then kindly ran the manual timing system (I did round 1, Simon did round 2 but his R3 score is in R2, I could have changed it but I didn't). Ian had to get away before the last slot, it would have been close between him and Pete if he had flown the 6th slot. Results

    Hi Marc Did it have a plastic fuselage? To me it looks very Dick Edmonds (EMP) maybe an Apogee or a Halton Special? Regards Pete BARCS1702

    Infinity or Explorer?

    Hi Al Morgan Good luck with this I think the F5J scene has split/separated (a little anyway) into NAN model and SAMBA model, versus Ultra Lightweights like the Infinity over the last few years, and I think you'll find that the guys who fly Infinity's will say "Buy an Infinity" whereas dyed-in-the-wool NAN model users like the Xplorer will say "Buy an Explorer BF!" For me, it's a case of "How deeply you want to involve yourself in F5J?" I fly an Xplorer 2/3, I also have a Pike Perfect F5J to me, they're just different not "better than", older yes, or dearer mebbe, so wait for some better-informed F5J pilots to answer, and see what they say, yes? As I said, good luck! Regards Pete BARCS1702

    Hi Marc Its my Dad! and I am the little fella holding his left leg. I was born 1974 and look about 3 so this photo is c. 1977. Geoff (Dad) is 76 now, migrated onto full size after aero modelling since a little boy. He stopped gliding his Duo Discuss about 8 years ago and is now riding motorbikes. He got me into RC gliding and I have been Flying on and off ever since. lovely to see that photo. I would love a copy but I suspect the negatives are long gone thank you for posting this. Did you start the hobby after this?

    Don't recognise your instructor but I flew in Richmond Park a lot in those days.

  26. No worries Simon We'll be at the field today and possible tomorrow (Monday) too - turn up anytime, leave at anytime. Hope to see you Tony

    Found a pic of a kind gentleman at Richmond Park letting a very young budding pilot have a go at RC soaring for the first time....Magical it was and I can only thank him eternally. Anyone know this chap doing the teaching? We must be talking early 70's. and
