HPI Savage OFNA throttle/brake mod

Fixes these issues: Brakes are weak Car shuts off when braking due to closing the carburettor MORE than idle setup Carburettor does not fully return to idle configuration, sticky throttle. Carburettor does not open fully even on full throttle. Needs some hardware, picture for illustration. Remove stock throttle/brake horn and install a normal one. After you have installed, be careful how you tune the brakes! The truck will front-flip or lock up all four wheels at maximum tightness! I recommend printing horizontally, with support underneath. You have to select a material with excellent layer adhesion, and choose 100% infill. Depending on extrusion calibration and other things, you may have to use a 2mm drill bit and 4,5mm drill bit to clean the holes. I have tried both PETG and taulman alloy 910, both seemed to work excellent. There are tips and tricks to make the model more solid. You must try to make it yourself with your printer and do a destructive test on the part, to figure out what settings make it the strongest on your printer! Do not ignore this warning! You don't want a run-away truck!
