What a bust. Lucas was not in a good mood at all. He remembers it differently, but it was pretty bad. He spent the whole morning complaining that we didn't go to the zoo. He did help and had fun at times, but it was mostly complaining. Hopefully I can edit what little video I got to show excitement. We got it to 80% and called it done. Loaded it up on a trailer for me to finish at home. He tried to drive it and blew up the speed controller. Stupid speed controller. Even with him in it the thing was a total dog.
Today I grabbed a speed controller that I had planned to use when I added a drive to my bead roller and gave it a go. 40amp soft start controller. Night and day difference. The old controller barely moved me on a single motor. With two motors it was so-so but I was very disappointed. This controller with a single motor was driving me all over my yard. It is slower than I want because of the gearing, but we will stay there for now. Once I get both motors going it will have torque to push Lucas and Mallie all over the place. Now I need to get to the shop to build a resistive throttle pedal and a switched brake pedal. The old controller used a hall effect pedal and the new one uses a 100kohm pot. I will have to get somewhat fancy because the pot is a full turn so 360° and the typical pedal throw is down around 15-30°.
After my test I opened up the problem controller and found two of the primary capacitors flopping around. It looks like it either got hot enough to flow the solder off or their quality control is absolute crap. I can't return it for a warranty return now that I opened it, but it was $25 and I am sure shipping would have been 10-15 so I am not worried.
