Ray, I thought that too. I thought that with this setup I wouldn`t have any problems with the VPP, as I saw in most of the post published, that VPP models have to be light. I made my third test today with a regular prop(GWS 11x4.7) and I have to fly the model at half throttle, and torque roll at 3/4 throttle.......dont know why, I`m totally loss with this setup......and I believe that I have good components.......may be the PPS props are too small for this motor....

thanks for the answers!
