Burning question, I got the legacy kit, built it as a twin. Tested motors multiple times. No problems. Took it off to fly it. Right motor pulled way harder than left. It flew, and quite frankly not too bad for the situation. Then it seemed great. Not until I slowed it down could I notice it pulling hard to the right again. Landed fine all was well. I can promise you she’s built square and true and I didn’t NOT have differential thrust enabled during this bout of trouble. I removed my battery and noticed it only had 7% left 😳. It’s a brand new (albeit cheap) lipo from Amazon. A “Youme Power.” 3300mah 4S 50c flying with both powerpack C’s with 35 amp ESC’s, and lastly 9x4.5 props. My question is, is it possible that a 50C rating isn’t high enough for that setup? Thanks in advance for the help.
