Viper motors

[bigbadtaz]

just and update got to run my viper rc motor and i loved it i was able to get 55mph out of my setup after 4 or 5 high speed runs i the motor was warm to the touch so i think i got room to really push ....btw the ground was very dusty with traction compound i sure a would have hit 60mph easily...my current setup is a viper 3.5 vst motor 30 tooth pinon and tooth 72 spur 2s lipo 5000mah 40c gen aces pack looking to go to 35 tooth pinon and a 66 tooth spur on a 3s
