The smoke got out..

So I knew the gearing was too long for the larger tyres, new gears on the way, I expected the motor would die from the abuse/heat (the 3d printed motor mount was certainly feeling the heat!) however it hadn't died after 3 or 4 battery pack, so I went for a high speed run, on the plus side it went straight, also on the plus side we get to replace the 20+ year old esc! downside I have to lend little TerraRoot one of my RC's until his parts get here doughtnut video

Cracked the 3mm ball joint out of it, testing it by sending it down playground slides, thought the link would break first but I seem to have over engineered that.
