Last night i finished up the wiring and we got the APM2.5 mounted in the rear.
First iteration is just using a servo cable Y to the rear ESCs (just signal for second ESC), this will eventually become a separate output channel on the APM, and a signal cable
Max has been working on removing the slop from the front end. I guess the amount of slop is acceptable when its using the plastic wheels and slow motors, but as we have ramped everything up and are now using rubber tires the slop has led to some pretty unpredictable
New and MUCH improved steering assembly. The linear actuator is driving the left hub directly with the drag link (original control bar) to the right hub.
My new linear actuator for steering arrived today. Max is busy fashioning the new steering assembly that we discussed over lunch.
Here is a size comparison between the old and the new :)
Yesterday I got in the new Hobbywing EZRUN-150A-PROs that I will be using for Project Power Wheels. They are much more programmable then the Traxxas VXL-3s’s I initially had. And once eddie gets bigger we can put some larger 6s capable motors in place without having to change
Last night I installed the cooling fans for the motors. It may seem overkill, but a cooler running motor will last longer. Today the new ESCs will be arriving, and Ill get those installed over my lunch break.
Right motor + gearbox assembly
Left motor + gearbox assembly
Motor heatsink + cooling fan
Max and I have started on the major components required for driving the vehicle. We will be mounting a potentiometer inside the steering wheel assembly, the APM board will use the resistance of the pot to determine the steering position, and control the steering servo appropriately.
