I have heard the P3 needs composite hub props. This true? Also while Im at it, I have been looking at prop upgrades. Mainly CF. I came across T-Motor. Now I spoke to one of the distributors for T-Motor and he said the Pro and the Antigravity are not efficient props but are the best props he has seen. I told him I wanted more battery life and faster speeds and he said because they are 9x3 props, they will not do those things for me. I am looking for a GOOD BALANCED CF prop. Any ideas? I will not be buying those POS props off E-bay so no need to mention LOL.
