Yep...Trial and error
I just replaced my 11x4.7's with 9x4.7's..
I can honestly say it flies much better both in fast flight and hover. I still have to try it in windier conditions and compare flight times, but there was more than enough lift at similar throttle position which makes me think that maybe the bigger props were not running at their most efficient load and speed.
Dont worry it wasnt my idea, I noticed David uses thes props on the rc explorer build. I assume they behave better in the wind and they are quicker to react to changes in engine speed since they dont carry as much inertia ?
