I have a tricopter setup and after the maiden flight I noticed it doesn't seem to climb out very well. I know I'm not overweight or underpowered , when I calibrate the ESC's and after calibration before restarting the APM hold the copter in my hand and run the throttle up it has ALOT of thrust, after I reboot the APM and arm the copter i can hold it ion my hand and run the throttle up and it has maybe 2/3 the power as before …. where am I loosing this throttle ??
I'm running 30 amp RCtimer OPTO sec's
also on a side note after the second time I ran calibration my motors no longer spin slowly after arming ….also I'm running a Turnigy 9x transmitter and I have to have the throttle reversed for it to work correctly…. is that normal….
