I just received my new Cessna 150 and put it together, I plugged it in to test it to discover the esc does not act right. It has an E-flite 60 amp Pro Switch Mode BEC Brushless esc (V2), model # EFLA1060B. When I tried to throttle up, the motor started fine but then immediately started to slow down until it stops, like I was slowly lowering the stick. When I bring the stick to zero and try to throttle again, the same thing continues to happen. I have tried changing some settings to no avail. If anyone has some advise, it would be much appreciated.
