    Aileron and flap servo arms in moulded wings.

    Hi Sorry To me the ultimate bodge to remove the servo arm and retaining screw is to cut or file a slot about 10-12mm in length on a direct line from the head of the servo screw at right angles to the servo cover.....if you do it right you should be able to insert a small Phillips screwdriver, along the slot at a shallow angle and into the screw head.......remove the screw and servo arm, then try the bodgery that OPF suggests to remove the servo itself.....oh, and finally, cover the slot with a short length of electrical tape to cover it up...... Good luck Regards Pete BARCS1702

    Oh well, roll on summer league.
  6. There is another possibility. Earlier versions of external bearings replaced the bolt you are having trouble with with a threaded shaft which ran in the external bearing. Such shafts usually had flats on each side so they could be unscrewed with a small spanner (I made mine myself out of a piece of dural) or with needlenose pliers. Since you haven't glued it in yet, you might consider replacing the screw with one of these shafts. Be warned, though. You might have some difficulty sourcing them. I got some recently from Graham Wicks at rcmetalbitz. They were old stock from the days when Tony Fu used to sell them. Modern exterior bearings do have the servo arm a push fit, but the exterior bearing housing stops them falling off. Servorahmen.de make these kinds of frames with inbuilt exterior bearings. See for example https://www.hyperflight.co.uk/products.asp?code=SRIDSM-MKS6110.
  7. Only idiots like me. I did it once (by mistake), and I will make every effort not to do it again.

    Aileron and flap servo arms in moulded wings.

    Servos glued to wing skins are a pain. I have had to remove then once or twice. If this were my model I would un-clip the clevis, then set about removing the horn and not worrying about the screw at this point. I would try to get a Dremel in there to cut the nylon clevis. If I couldn't manage that I would turn to a soldering iron to melt the clevis. I would use my 40watt iron to get the heat to soften/burn the horn. At this point it gets brutal... with a scalpel and taper nosed pliers I would be trying to remove the horn by yanking, twisting etc. That nylon horn has to give way at some point. Once removed I reckon I would be able to get a grip on the servo screw with a pair of pliers. As a seasoned flier you, like me, may have a large collection of spare horns. (That clevis could do with a 2mm locknut btw)
  9. Thanks, good ideas. Nothing glued yet. Still thinking. Do some people not screws arms on at all ? Just push fit.
  10. I think these two answers are probably too late by the looks of your picture.....Well, it’s one answer really with two ways of doing it: Make the servos removeable! Method 1: Wrap the servos in tape and glue them in, following the detailed instructions on Kevin Newton’s website. These are almost 20 years old, but are still good. http://kevin-newton.blogspot.com/2001/01/mounting-wing-servos.html. Method 2: More common these days is to use a servo frame glued to the wing skin. The servo can then be screwed to the frame and easily unscrewed again. I don’t know a really good build log for this. Perhaps someone else does? Servo frames can be bought, but can also be cut from plywood that is half as thick as the servo. It looks as if your servos have been glued to the wing skin without the tape that makes removal easy by cutting the tape. My suggestion in these circumstances would be to disconnect the servo arm, get a pair of pliers and yank on the servo arm. A vertical yank can be good enough, but if this seems to be damaging something, try exerting a horizontal twisting force to the servo. Replace using one of the two methods, being sure to abrade the old epoxy without going through the wingskin. (Can you hear the voice of experience speaking?) It's usually quite easy to see when you’ve got back to the original surface. I use a smallish diameter Dremel grinding bit.
  11. You are all clever people. Aileron and flap servos in moulded wings. What is the best way to attach the arms so that they can be removed/replaced or moved round ? I have tried making right angled screw drive short enough. Failed. Tried replacing cross head screws with socket head screws. Couldn't find any the right size. Help. Ta Robert

    Sad to say, but I suspect that's the correct call.

    Weather call;- Having this morning discussed the latest forecasts with both Graeme & Nigel ( who were between them to have been staging & running the comp), with persistent rain being forecast until some time up to the middle of the afternoon, I am sadly calling the comp OFF I wish to give a big thank you to Graeme, Nigel, Jp & Pete for all their help in the organising of this months competition. I very much appreciate this. Stu Whitesheet Comp Sec.

    With the various forecasts all being unsettled especially in the morning for Sunday, I am delaying making the weather call until 9.00am tomorrow (sat 22nd). This will give us the best chance of getting a comp in. Stu, Whitesheet Comp Sec.
  18. LOL No problem. I know what you mean though, sometimes what works isn't good enough!
  19. Still got a Sonata (built as designed) and it still flies fine - very therapeutic to fly on a calm, sunny, thermally summer day
  20. F3F Euro Tour 2020 26th, 27th and 28th June 2020 ESSA are proud to be hosting part of the F3F Euro Tour and the World Cup Entry cost €45 Online Entry will be open from the 1st March 2020 this will be handled by GBSRA: http://www.gbsra.co.uk/competition-entries Any questions or further info feel free to contact be or JP or Check ESSA website for more details
  21. A real long shot I know but does anyone have a wing joiner for a Munzar Big Bird they would like to part with for cash? I have tried to contact Radek Munzar with no success.
  22. In a previous life, I flew a Balsa Cabin Sonata, built as per designed and it flew fine. People have the propensity to over think things. Good question if you are not in the know but there were no vices in its handling.

    Elevator - use only one side for control surface

    Hi all When I had a Sonata I just cut out a strip of the non-moving elevator and converted it to a "standard" two-sided elevator. Took about two hours to complete and , as far as I was concerned, solved the problem completely - simples! Regards Pete BARCS1702

    Elevator - use only one side for control surface

    I'd be worried about turning any slip/skid could cause odd responses as the elevator got more or less airflow over it!

    Elevator - use only one side for control surface

    That looks like the Sonata tail surfaces anyway - just checked the plan fo a Sonata E, which still had the single sided elevator. John M
  27. Balsa Cabin's 2m Sonata used to have this arrangement. It was adequate.
