Sariel Posted April 26, 2020 Posted April 26, 2020 (edited) A simple medium-sized model built to test a 3-speed RC transmission design that can be shifted while driving. Doesn't look too great and certainly suffers from open differentials, but the transmission works flawlessly. I'll have a more refined transmission design with free instructions in a few days.

hjxbf Posted April 26, 2020 Posted April 26, 2020 Very curious to see how the transmission is built! I believe I built a copy many years ago of (your?) two speed gearbox which could switch while driving. It was basically a 12-20 gear combo mounted on a pulley pair, rotated 180 degrees by a servo to invert the ratio. Very cool concept for light cars! but suffered under excess torque. As this car is significantly bigger, I assume the transmission is a lot more robust. Looking forward to seeing it! Quote
