Hello. I was needing some help and hoping somebody could assist in figuring this out with me. I have the hanger 9 alpha 40 rtf, with the evolution .46 motor, and i have had some issues that my club cant figure out. I can get it to run fine if it is level but as soon as i pitch up, ie takeoff or a climb, she just seems to lose fuel pressure. We have tried to up the mixture, i changed fuels, went from a 10 nitro to a 15 it did give it more power but in a climb she will stall out. Any suggestions would be appreciated.

Thanks.
