I moved your thread here as it is more likely to get seen in this part of the forum that is dedicated to power systems for our helicopters. There should be some answers in here for similar questions posed. Good luck with the build.

I also have the 500 pro 5 blade. I'm running a 4015-1070 logo480 motor main gear is 162 and 11t pinion gov at 1520 I believe. You will need to move the tail servo to the boom or it will rub the fuse. I initially modded the frame to move the servo higher but still rubbed ever so slightly. Click image for larger version
