hpi wheely king on grass (7700kv motor)

wheely king 1/12 + motor 7700kv brushless + castle creations mamba max pro ESC+ 5000mAh Lipo
stock motor pinion 21 teeth (not optimal)
run time = 19 min on high grass only or 28 min on small rocks only.
it does not look very fast but it is. i could not even pull it to the maximum cause it was bouncing too much already at 2/3 rds power.
the max. speed measured on grass by onboard GPS is 35 km/h (not maximum speed on the throttle).

be carefull with the transmission, 3 runs after i did the video, 1 gear in the transmission box litterally broke all its teeth. costs a fortune to fix (1/6 of the price of the car). i would recommand setting your esc on the lowest timing (smoother accelerations, but still powerfull) setting. also if you have some time to do it, i would recommand opening the gear box and making the gear protection spring a bit more tender, less tense by compressing it several times. If you do so, be carefull not to loose the metal clips of the metal axis (i did).
