My re-release Tamiya Hotshot is a lot of fun but it's turning into a bit of a workshop queen. Already had to replace a bumper stay because of some tree encounters (my fault) and now the speed controller has failed with what I learn is a common fault.

The much cheaper Grasshopper which my 8yr old adores just doesn't give a shit and is apparently indestructible.

Heat is an issue with the Hotshot. The electronics bay is fully enclosed which back in the mechanical speed control days with external resistors wasn't an issue, but now the electronic controllers need some cooling and the only vents are either end of the box where the driveshaft passes through. I may drill some holes in it.

Space is tight and I don't know if I can get a mini fan in there.
