I have a problem with engine power in APM and I’m almost sure, that is problem of APM.
Details of my quadcopter are: ESC’s are Emax BLHeli 12A, 1A BEC, engines DYS BX1303-2300KV and RC system is Hitec Aurora9 Tx and Optima 6 Lite Rx.
My problem is as follows: After arming engines, I have no full power on them. I can push the throttle stick to about 50% and engines are reacting, but after 50% nothing happens.
Engines are not accelerating.
I’ve done of course MIN and MAX of throttle settings and during this calibration engines are accelerating to 100% of throttle stick. Seems to be okay, but when I disconnect power, connect it back and arm engines, there are no changes and still the same problem.
I even upload ArduPlane and ArduCopter software again, because I’ve read somewhere that this method is a cure for a lot of strange problems with APM, but it doesn’t help anyway…
PS: Engines and ESCs seems to be okay because I’ve test them on OpenPilot and on this platform engines react positive on full range of throttle stick and my quad flew on about 30 meters above ground and on APM only on about 1,5m.
