Ned, would you like input to this thread? The following components were driving my 917 around the floor a few minutes ago: Steering servo Hobby king HK5320 This seems to be powerful enough and it's small ESC Aliexpress F05427 10 A brushed two way no brake Needs two Li ion cells to run the motor I wi...

It sounds like I do need a different motor. I have several so maybe I'll try rewinding one. My ESC on and off switch worked but since I put the batteries in from the bottom I deleted it and put a jumper on the board.

Love to see you video, Wes.

Kim, what battery voltage are you running your motor on? I tried that same ESC on about 5 volts and couldn't get a 6volt motor to do more than tick over. I'd love to use one Li ion cell but I've planned on two. Maybe I need a different motor. The ESC did power the radio and servo ok on 5 volts. I'm ...

It's time for me to build a test track; my car chassis is read to test. I'm waiting on Li ion batteries but it's been sort-of tested with a 2 cell Lipo pack and it runs and steers with the servo. The receiver is a Frsky mounted in the front. I don't think the Flysky receiver would fit there and anyw...

Wes, I've got to put some more effort into your servo arrangement. When I tried it I couldn't get it to steer if the the cars wheels were turned to the lock. But first I need to get my car running and try it on a test track. I have one of the 10 amp escs from aliexpress that works but not on one li ...

Here's rev 2 of my servo steering. I think this one will work and it actually fits inside the 917 slot car body. I don't think everything would fit in an open car so there's still more room for development.

Here's my first try at a servo chassis. The servo moves the two side magnets to repel the one in the middle and steer the car. It's all from scratch with the exception of Ned's steering knuckles. It sort of works but needs more development. I need to make it more compact and more adjustable. Nick

Wes , I'm impressed with your servo steering solution. I'm working on a method that uses magnetic repulsion rather than attraction but it's rather more complicated than yours. I'll post a photo when it's farther along. I'm using a servo like yours so maybe I'll try your method also. I'm afraid rever...

My steering coil winding has not worked out. I've made three; number 32 wire comes out at about ten ohms and gets hot at 1.5 volts. The first number 38 wire coil wasn't very neatly done and I broke the wire before the form was full. A second carefully wound #38 coil measures 95 ohms and sort of move...

Hi Ken, I guess there's no reason you can't start building track. I need to make a real test track. My current one is some wire taped down on a small cutting mat. I have an idea for servo controlled steering that I intend to try. The servo will move a magnet that will steer the car. My only concern ...
