I've had great luck with:

26cc 8500 18x8 menz and a pipe
50cc 6850 23a Vess stock muffler

more rpm means better pull out as long as you are comparing similar sized and brand props. my mld 28 will hover a 10lbs plane below 1/2 throttle with good pull ou and turns a vess 18/6 at 8200 rpm on stock muffler. my dle will turn a vess 23a at 7400 rpm and hover a 19lbs plane under 1/2 throttle with good pull out. my da 100 don't have numbers on that yet.
