We just received in the 775pro today and ran some testing tonight with the Vera planetary at 1:1 ratio.
We made a simple wooden jig with 2 motors assemblies spinning two 4x2 Colson wheels (flywheel style).
It could easily launch the boulder 20+ feet. This was just a quick hookup to a FRC battery that was at 12.8v.
We had not planned on using these for our shooter as we have something else planned.
Since the thrown together jig showed such promise we are going to go ahead and building an optimized (aluminum) jig with the control system. We be incorporating the Versa encoder kit with talon and really see what it can do when optimized.
I will try to upload the video from tonight sometime this weekend.
So far I like the motors, we shall see, the encoders are next...
Aloha!
