Ebike servo tester throttle

thingiverse

I designed this custom throttle for my Ebike, using a helicopter ESC (speed controller) and needed an easy way to control it. This throttle will work with any Car, boat, or plane ESC. To control a brushless motor easily, connect its 3 signal wires to a servo tester. Just remove the potentiometer from the servo tester and attach a new one (20k pot) with an extension cable. Here are the parts you need: * 20kohm potentiometer * GT2 180 belt * 2x M3x35mm screw * 4x mini M3 bearings * 1x 688ZZ bearing * 2x spring You can buy a cheap servo tester on eBay at this link: https://www.ebay.co.uk/itm/Multi-RC-Digital-ESC-Servo-Tester-3CH-ECS-Consistency-Speed-Controler-Power-GW/292314083669?epid=27008389654&hash=item440f46f155:g:xXUAAOSwtTVZisEw To assemble the throttle, glue the potentiometer to the potentiometer pulley using gorilla glue. First, mount the belt on the pulleys and then install the bearings. Make sure you leave a little bit of slack in the potentiometer so that when you release the springs, they won't damage it if they hit its limit too hard. To complete the setup, simply calibrate the throttle range on your ESC. For more information, watch this video: https://youtu.be/RzK90LfxRpQ
