Maytech remote mod, grenade

thingiverse

I would advise not using this design due to its resemblance to a grenade. PAINT IT ORANGE! A bit of work to put it all together but it worsk great. Rough idea of how it goes together. It is a cylinder with a top and bottom cap. The top has 2 sleeves, each with a piston with an embeded magnet. One sleeve has a tension spring in the bottom for the throttle, the other has a spring for the brake function (this is on the far side of the throttle lever and hard to see in the pictures). The PCB boards with the hall effect sensors are mounted against these sleeves. LCD screen is potted into the cylinder, battery and RF charge ring in the bottom, the tactile switch is clipped off and replaced with a switch mounted in the top, potted in place and covered with the origional rubber button from the controller housing. This switch is attached to the PBC board via wires to the holes where the other switch was removed. All in ASA and smoothed for waterproofing.
