David perry 1 Posted April 17, 2020 Share Posted April 17, 2020 Ive just bought a thing called a pindiquio, an epp glider, from robot birds. Its a tiny thing with a span of 800mm. Ive bought it to modify so that it can be used in and out of my garden during lockdown. The mods will be (probably) ailerons and (certainly) barn door flaps. I will add a teeny electric motor too but it's not a hotrod and I want to keep it really light. I know 5g servos will be more than adequate and I have some, but its the "more" bit I dont like. I have very little experience of 2.5, 3 or 4g servos so not sure whether they'd pull the flaps down without stripping. I'll use 5g on the elevator but those flaps! Thoughts?

David perry 1 Posted April 17, 2020 Author Share Posted April 17, 2020 Actually, thinking this through...one 5g would do. But better might be to use blade spoilers...more complex and thus more fun anyway! Heavier though... Quote Link to comment Share on other sites More sharing options...
Simon Chaddock Posted April 17, 2020 Share Posted April 17, 2020 Any idea of the likely all up weight? If less than 300 g and provided the hinges and linkage are efficient 3.7 g servos will do for everything including the flaps. It is after all a tiny glider not a 100 mph EDF. Micro servos do not strip gears under load (they can be held stalled) but only as a result of sudden reverse loads from crashes and 'hanger rash' handling. Just make sure each servo uses its power moving the surface against the air flow rather than friction. Just saying. Quote Link to comment Share on other sites More sharing options...
