prometheus gears are pretty heavy to be using on a high speed setup, especially in something that doesn't have a box mag and isn't constantly in full auto, it'll be really hard on your motor, especially if you have active braking.
Get a lightweight gearset, standard or high speed ratio if you're using a 7.4v, double or triple torque if you're using an 11.1v
400fps, G&P M140 motor, prometheus double torque gears, 7.4v lipo + triggermaster = 900rpm
