Hopefully others who know that specific motor will chime in.
Note: the motor is not maxed out yet......everything should run real nice.
***Don't count out 5.5X5.5 yet.
APC 5.5X4.5 will be more fun than 5.2X5.2 Graupner but consider picking that up sometime and see how you like the speed etc.

Thanks. I'm about the hit the field in a few minutes and will see how she does.
I'm going to start with the 5.25x4.75 and check the temps before moving up as I don't have a heatsink on it right now.
