Although I did not fly up to my old levels of competence , I did learn to fly ACRO on the 250mm quadcopter I took along with Dennis' help . He created a monster !

Recent winter shop projects are well along their way . Rebuilds of 2 quadcopters and a Trifecta build have been completed at this juncture . The latest rebuild is of my old V22 Osprey . I always had problems with this one with regards to the nacelle tilting mechs and their setup in the Happy Sundays firmware . A new design around a pair of bargain bin (HK) buggy type 2:1 gear ratio transmissions are at the heart of this . The basic idea is to use these gearboxes to each drive an 7mm fiberglas arrow shaft to do the nacelle tilting . A heavier duty MG995 servo will be used to connect to an intermediate jack shaft to drive the inputs of the gearboxes . Simple 3D printer type GT series gears and belts make the jack shaft to gearbox connections a snap . Future expansions may see a second servo be added to drive each gear mech . For now , I have both being driven with one servo .

All parts so far have been 3D printed for this project . Quick design changes can be realized in...Continue Reading
