so i am getting a xtreme DD tail rotor kit and was wondering what size GWS prop i should use with it. My guess is the 4025 or should i go with somthing a bit more pitchey like a 4530 or a 4540. My setup is stock except for a xtreme swash and xtreme skids.:dontknow

Are you running a V1 or V2?

Get several props, they are only like .90 each from TowerHobbies.com
The smaller props work better on a lighter bee. If a smaller prop also seems to work as well as a larger one then use the smaller one. It will run more efficiently and the motors life will be extended.

If your running a V1 try a 4020, 4025 and 4030 if a V2 then 4025 or 4040 should work best. If you start adding weight to a V2 then id suggest a 4530

First two numbers is length in inches, second two numbers is the pitch in degrees.

Ive looked around and I cant seem to find 4020 or 4030 props at any of the suppliers I can think of (Ive found 3030's, 4025's, 4040's, and 4530's). Ive tried BP,Tower.......so many I cant remember now.:dontknow

VL, or anybody where are you finding the 20's and 30's at?

Got mine at BP and Tower myself, that was many months ago though. The props you listed are great, youll find a good one in that diverse group so dont stress over it. :thumbup:
