I played it safe on gearing and timing as well, safe enough i was under powered compared to the rest. Rear motor it will run all day with no heat issue, and I have the speed to run with the rest. Bigger vents on the can I think is what the Tekin may need. The gearing I was using was 69/31 under 20 degrees of timing in the motor, blinky mode.
