Go the final install done on the motor today. I spent about an hour making a blanking plate / heatsink, and then drilled a couple of holes in the CF radio tray so that I could screw the ESC directly to it.
Very close fit to chassis support bar, but there is clearance:
Top link touches motor just before full travel, I just need to add some O rings onto the damper piston to limit the travel slightly.
Final install. 3S fits easily into the battery tray with a Velcro strap, and speedo fits neatly on top of CF radio tray
And here's a quick video of the test run. Can't really get to full throttle due to the size of the garden, 0 degrees timing and 50% punch.
