Hey guys quick question, I have the UCANDO 46 and i put on a 70 surpassII on it and I don't know if its me or not but the video review on tower hobbies, that guy has no problem holding a hover, and i built it exactly like his, every detail and CG. But mine falls out of a hover after only 4 to 5 sec at full throttle. slow and Straight down fall out. running 14X4 prop just like his with right at 9000 RPM. what gives, any ideas or help would be very much appreciated.[][][][][]
