I tested a friends orginal LRP Sphere esc against my spare novak. I didn't have alot of time and only a Novak 6.5 with bonded rotor to hand.
Sphere = 196 watts @ 21.3k rpm, 87.1% efficiency @ 34.5k rpm
GTB = 210 watts @ 20.7k rpm, 92.5% efficiency @ 34.5k rpm
There may have been a problem with the sphere running this motor. The bonded rotor is past it's best so could explain it. If I get another chance I will test with a sintered rotor.

There are a lot of discussions between the performance of the 4,5 T from SPassion and LRP/Nosram, so as between the ESC from the same brands.
Could you bring some light into this ?
I know very well Robert ( the owner of Robitronic) and when there are some more tests here, I will gladly invite him for a "TOUR".
thanks anyway

Hi Pedro
Thanks for your appreciation.
That's is cool that you know Robert, next time you speak I would be very grateful if you could ask him a question. Is it still possible to register the dyno software?. I had no reply from the email address.
I would be very wary of testing a 4.5t motor due to the high current and rpm. When I tested the 6.5 it was a little scary, it would be nice if the motor manufactures would tell us max rpm of each type of rotor.
I hope to compare other esc and spec wind motors in the future.
Regards, Jevon
