Paul Williams Posted July 6, 2008 Share Posted July 6, 2008 Currently building a Sopwith Pup, the aircraft kit uses a lot of linkages I would prefere to installed 4 midi servos in the wings. Any body done this? will there be a problem running 2 servo's from 1 output on the rx? Quote Link to comment Share on other sites More sharing options...

Myron Beaumont Posted July 6, 2008 Share Posted July 6, 2008 Paul I am a proud builder owner of this model and I built the aileron system as desgned.No problem with one futaba 3003 servo in lower wing powering the lot (differential built in as well using a circular servo disc as per plan) .Simple -& for a slow flier ie non aerobatic m/c where maybe a thou or two of slop creeps in it's quite adequate plus no long servo extensions of course! Possible source of problems ? Must admit I prefer mechanical solid connections over 'lectric ones Call me old fashioned ' whatever Quote Link to comment Share on other sites More sharing options...
Myron Beaumont Posted July 6, 2008 Share Posted July 6, 2008 Ps Paul .Have looked at your photo more carefully and think theres too steep an angle from the bellcrank to horn ? Is the bellcrank support in the right position .I remember slightly altering some positions of certain linkages etc to arrive at a free linkage scenario ie 'cos the rib holes & my servo mount werent where I wanted them according to the plans .If I made another one it would take me half the time but maybe not as much pleasure.Good luck The choice is yours?

Paul Williams Posted July 6, 2008 Author Share Posted July 6, 2008 yes your right I stared at this for some time last night, I fitted the servo where the bellcrank would have been expecting no problems but has you say it would require either a very tall servo horn or some clever cranking of the rod, might try the servo in the other way up. Yes the crank support is fitted to plan.Did the plane have linkages from top to bottom wing controls on the full size? or is this some thing built into the model? if I message my email address have you any pictures of yours love to see them?
