RE: Extreme Flight 88
My 17# 13oz EF Yak has a DL-50 on stock exhaust. 7400 RPM on a Xoar 22x8 makes this thing rocket out of hovers. Your pipe setup is slow to pull out of a hover? Something is wrong with your setup. The pipe should be better than my setup by a few hundred. I'm no pipe guru but the header could be the wrong length....and/or wrong prop.
