Cat setup

[marko500]

I have a 36" Bittburger cat. It came with a Hacker B50-8xl motor, Hacker Master 77 esc, a Fine Design Turbo Trrans. The gears I have are 40, 60, 66, 68, 78 tooth. Props I have are x648, x447. Would like to run 12-21 NiMh batteries,lipo in near future. My questios are 1 will this motor work, 2 what gears to use. 3 which prop 4 what battery combo, or lipo combo. Will be used for sport running. Hope to get 45-50 mph? I am willing to tweak this in the spring, just don't want to be laughed at first time out. Any ideas? Thanks!

You will have to narrow down the voltage window for us to determine if the motor will "work", you almost double the voltage from 12 to 21 cells. What will be the LiPo voltage? Just not enough info in your post.

I doubt you'll ever get 50 with the 12-cell setup, you'll need more voltage. With 21 cells or 6S you should be able to do so, for a short tiem anyway. Decide on the voltage and we'll be able to help better.

I,m looking at 3 different voltage setups 2-6 cell packs=14.4v, 2-7 cell packs=16.8 volts, or 3-7 cee packs=25.2 volts. Kind of leaning towards 16.8 volts. I would like to go to lipo but don't know what the speed control can handle.
