I think the numbers for the HET 2W23 were stupid after discussing with a mate who is a lot more in the know that I am. Something would pop very quickly. I substituted for a Mega 16/15/3 and got these numbers,

17.59 Volts
73.2 Amps
1288 Watts
? RPM (too dark, will retest tomorrow)

Still too hot considering it's rated for 30A continuous. I'll have to prop down for this motor. Will pick up some smaller APCe props tomorrow and experiment tomorrow evening. Great that it's so easy to swap motors in and out of this model. Either the HET 2W25 or the Mega 16/7/6 will be the next purchase for this project. I was hoping I could get away with what I've got but looks like I need a new motor.

I want to get this FJ as fast as possible but I think, in comparison to the Projeti thread (which he got to 165mph on a 16/15/3), it's a bit more difficult because of the mount obscuring the prop from airflow. Not a lot of the prop is seen from the front of the model. Got to be bad for performance.

This is going to be a bit of a journey but I want to get to 130mph if possible on 5S.
