Hello

I did a test by changing the propeller.
I installed a 21X14 mezlick now I no longer have ESC overspeed but the engine consumption is higher (identical to a 21X13 on a Q80 Normal).
Currently I have 5000Mah batteries once the q80 senstrol well set I will try with 4600Mah batteries.
Soon I will reassemble the PT propeller model 21X13W by modifying the maximum engine speed parameter (6000-- 6500 rpm) in order to shift the ESC overspeed passage point.
At the end of the vetical descent I have to accelerate because the brake is really phenomenal.
You have to manage the throttle handle differently, it's impressive.
