Since we are talking about servo installation, here are a couple of photos of a frame that has taken me about a day to program into my CNC router. It’s for my Personal Best Pitbull, which is having all its electronic bits and pieces replaced. I’ve considered upgrading to HV, but this got complicated and in the end I decided to install new Futaba S3150’s, but only after I had ripped out the original frames. The design is basically the Baudis original, reinterpreted because I couldn’t source any 5mm ply. This is made of 6mm ply, which has to be routed out so that the 10mm thick servo sits flush to the bottom. The bearing frame (which is a Baudis original) also sits flush to the bottom. I’m pleased with the way that it turned out. It’s the most complicated piece I’ve made with the router, and the remaining three will take less than 10 minutes each to produce. Along the way, I also programmed a frame for the MKS HBL6625. Servos are removed by undoing the screws that eventually will fit in the holes you can see. Probably could be done on the field if necessary.

Hi I got it out the loft hope picture are ok

Hi Mattc and Tooks Welcome to the BARCS forum, and I hope we can continue to help out with your silent flight questions Coastal soaring sites have been a revelation to me, the smooth lift coming off the water a constant surprise....... Keep it up lads and happy sloping wherever you enjoy it Regards Pete BARCS1702

Quick update - this trip is now not happening.

Hi Matt, I’m a newbie here too, it’s a fantastic wealth of information and knowledge. I’ve not had a question yet that I’ve not been able to get an answer to by searching. I love North Norfolk, go there a few times a month myself and have even managed a bit of flying off the cliffs and dunes between Hunstanton and Old Hunstanton. There are quite a few ‘micro slope’ sites along that coast. Where do you fly? iain

Please excuse my rudeness in not posting here before my first post, I didn't see this bit of the forum! So hello everyone, my name is Matt, I'm 42, live in North Norfolk. Work as a water distribution infrastructure engineer, been flying RC for 25 odd years. Mostly slope until I moved, since then, a bit of IC, electric and getting back to slope now I have a site. First got into RC with an EMP Apex 98, which I flew hand tow and slope. Cheers Matt

Thanks Tim. One of the things I try with each PG is to find and test economically priced "alternative to mainstrem" makes of servo's that really perform. The first rate Emax3352 from Bangood for Aileron's is now pretty well known about. At around £7-8 a pop you simply swap in a new servo if you break a gear which I havn't managed so far. Im sure this servo could also be used for flaps which are of a more normal size compared to the PG BF. So for the flaps I went with a servo I've used before which has proven to be up to the job, the Power HD 1810MG. You have to make your own mounts for these but at 17g and 12mm thick they have so far been very good with a strong geartrain. If you have a 3D printer servo mounts are not a problem! Around £12 a pop from HobbyKing. Having said this Flightechs new range of Kingmax servo's are great quality at a very reasonable price and have a wide range of commercial mounts available. No one here had ever heard of Kingmax servo's till the entire German F5J team used them excusively at last years F5J Euro Champs. They didn't do too bad as a team!! Re the slightly non matching canopy on this PG I didnt have a fleuro yellow one to hand so I just used what I had. I'll lay-up a matching one sometime soon. Your OCD will not be a problem then
-
Thanks Bob. Looking forward to seeing you all at RG.

Thanks Pete. We've arrived at the conclusion that if you want a really nice surface finish/shine like the professionaly manufactured models you do have to use more epozy during the lay-up. The small amount of weight it adds is pretty insignificant and you end up with a nicer surface finish. Kevin's latest wings are mega shine! I still managed a few very slightly dry patch's on the BF.

Lidl are selling a good looking hot glue gun in a case at the moment for £7.99. It has a short period cordless facility too but mains not battery.
-
I love hot glue, and use it a lot. I usually mount servos with hot glue, BUT I then epoxy a strap across the "top" of the servos to tie into the lower skins of the wings. The strap will be whatever suits, aluminium, steel, ply. Looks ugly, so does not make for pristine photos taken 20 mm from the servos (al la) certain Continental forums, but is in my mind 100% more secure than mounting servos to the top skins only (with frames etc. as many like to do). Changing of servos has to be a workshop job, but easy enough to grind or cut the straps away with a Dremel.
-
I learnt the hard way not to wrap servos in masking tape. It goes brittle and crinkly. Best approach I have found is to use heat shrink plastic wrap on the servos and then glue in with some IC-2000.# certainly wouldn't use hot glue sticks.

Hi Slap I was working with Henkel Chemicals/Supergloy when the first hot melt guns came on the market in the UK.......there, that shows my age, doesn't it? We, Henkel, got a LOT of complaints early on, from people who didn't understand the basics of which adhesives were best for what jobs, and complained of failures of the bond, and other perceived faults because they hadn't read the "instructions for use" The hot melt gun was originally designed for "tacking" ie temporary fixes, and the flexibility of the hot melt adhesive was described as a fault rather than an advantage because users, initially didn't realise this. For example, hot melt adhesive wasn't designed for its gap-filling properties, although many of the original users complimented it on doing just that! Also, hot melt adhesive is not, in itself, particularly strong..... Many modelers remember Stabilit Express, another flagship Henkel product, and didn't realise that this was a polyester-based product, and therefore great for repairing the polyester fuselages available at the time.......when epoxy fuselages became the norm, Stabilit rapidly lost favour So, how does this reply apply to what you were asking? Hot melt is NOT the best product for mounting servos - it flexes in use which affects the precision of your servo linkages and it doesn't have a particularly strong bond, especially on dusty surfaces. If I had to suggest what I thought was the best product for servo mounting, particularly if you weren't using a servo tray, I'd say don't use a hot melt gun, wrap the servo(s) in masking tape or electrical tape, and stick them into the servo well with five-minute epoxy. If it was sticking things like on/off switches to fuselage sides it's great, the proverbial sh*t to a blanket.....(sorry!).......but, temporarily fixing something in place, and using a different adhesive to to replace it, when fixing something firmly over a long period - magic! So, read and check the instructions, especially the instructions for use, and what it is actually recommended for bonding, and you won't go far wrong, good luck Sticky Pete BARCS1702

RX antena placement/noisy servos advise on an Alula
cirrusRC replied to Slap's topic in RC Equipment
If you want to remove the welcome sound, just delete/rename the following file on your SD card (it used to be called tada.wav) SOUNDS\en\SYSTEM\hello.wav you can download the amber sound pack from here. http://open-txu.org/home/version-2/v2-2-resources-2/ backup your sounds folder and then copy the new sounds across (there are lots more sounds in the amber pack). You can of course create your own sounds and assign to switches. -
Colin & Kevin, Well done, on a great looking plane, with the BF version did you go with the usual flap servos or did you go for something slightly beefier ? Oh and the orange canopy really messes with the OCD in me But seriously impressive achievement chaps you should be proud.
-
I just followed your lead sir! thank you
-
Thank you Mark. That Amber sound file you have with no Open TX greeting sounds good, ok for you to send to me please? . Does one just pop it in and overwrite existing sound file?
-
Thinking of getting one for mainly for servo/wing attachments and perhaps other modelling jobs/fixes. Will this do the trick? https://www.argos.co.uk/product/7004937 Thanks

Hi Rob, Thats perfect, just what I am after, thank you. Photos would be great. Speak tomorrow. Leo
-
hi Leo it is the pro with the long thin nose I purchased it from hyper flight with the idea to make my own wings but have never got round to it .I will get it out the loft and take a pic for you tomorrow . It has the boom with the elevator pylon and rocker already fitted . thanks Rob

Very civilised Phil!

Hi john, i’d certainly be interested in manufacturing a couple for personal use. Are you interested in parting with said items? best wishes, mike -
Looks great, Colin (& Kev). Hope to see it perform at RG Bob
