Bench testing of flight controls...everything seems to be ok.
just some details on firmware (AC3.2rc14):
- added the fourth servo and changed the control laws to fit a 4 points swashplate layout;
- added extra servo for engine throttle control mix...not sure it will work fine (i have made some tests only on a little .30 helicopter in stabilize and acro mode);
StatorGator and Futaba GV1 fitted as a good and reliable backup solution, even if expensive and unfortunately hard to find in these days.
