Cool, Thanks for the tips. I also dont think I'll need any extra power from the timing advance.

I did a little rearranging and harvested a small fan from a laptop for the ESC, it was getting up to ~140 yesterday with ambiant temps in the low 60's, so I turned it 90deg heatsink forward from the pics in the first post(hard to see with all the wires) and if that isn't enough I'll hook up the fan. I'd like to see it about 60deg above ambiant. Got bored waiting for the sun to come up this morning, LOL.

Ok graphs with the 14/65 gears, I split up the data so the graphs aren't so messy.



Temp1 is the motor temp2 the ESC.



I could probably push it harder yet, but ambiant was 43f when I made this run so I think this is the limit. Speed was decent up a little from the 68t spur, darn near cleared the down slope on the far side of the road, wheelies up to maybe 10-12mph. Stuttered on one start up. I'll turn up the start power and see if it helps. Then back to the Ammo for the heads up portion of this thread.
