The tractor battery swap mostly works, but it's weird. The blade motors run just fine, but the wheel motors run very slowly at full charge and slowly speed up. I don't know if it's an issue with the ESCs (same ESCs as the blade ones), the control CPU, or perhaps the accelerator position sensor. May have to do some detailed debugging.
A while back, we were discussing display options for a plant watering sensor. It occurred to me I could make a smile/frown display pretty easily and said "I just need some rubber tubing and a servo!" My friend Chris grinned at me and replied "If I had a nickel for every time someone said that to me!"
@mavica_again Yeah, that paperclip. I thought it would attach the image. Later I figured out I can just drag an image into my post.
