Motor comes off between 60-70 celsius and have about 1200mah battery drain for a 5 minute race so all seem good and acceleration and top end is right up there. Also confirmed with a friend who runs R1 wurks 17.5 and his draws 10 amps too.

I have a Team Powers Actinium as well and when testing it on my Motor Checker it had an unusual ability for a 17.5, running it at the lock, which was about 60 degrees of timing, it spun a LOT of RPM and didn't seem to hurt its low-end. Also, at 60 degrees my motor was only drawing about 6.5 amps, not 10 or even 20 amps that my Tekin 17.5 drew at 60 degrees of timing. Each motor is different, if I had tried to run my Orca at 60 degrees it probably would have just given up, it wanted only 32 degrees and any more made it completely lose its low-end.
Offroad is a different animal, mid range and "wind out" on the top end is much more important because low-end grip is limited. You're also on the throttle proportionally less than onroad, giving the motor time to cool in the breeze. If you get the best results cranked, run it cranked.
This is a highly inexact science, and the Team Powers motor has been the oddest one I have tested, but it's a great motor performance wise and responds well to extra timing.
Just a little anecdote though: My Team Powers 17.5 draws 50-100 milliamp hours MORE power to run 50 laps of 1/12 scale than my Trinity 13.5 does to run 54 laps of 1/12 scale... in the same 8:05 range. There is some serious efficiency difference here.
