was that the Master or APC 11x4? Master 11x4 on the Leo 37 is great APC 11x4, dun like it, not even the 11x3 works well
for learning i found the APC 10x4 best coz you could get instant go and it really pulled out, i don't like to hang on constant throttle constant throws, i prefer a bit more throwing about and a little more active
