gearing help on orion core stock

[Reuben]

does anyone use this motor or know anyone who does?

because yesterday i was running it (along with multiple problems with my car that i have to fix) and i couldnt seem to get the gearing right on it. Plus there seems to be very little information about the sweet spot of this motor, Some sites say it runs very much like a MVP.

the model number is: ORI20021

anyway here is the dyno print that i recieved with the motor if it helps:

Robitronic Pro-Master
battery simulation: 7.2v
RPM: 26.518 RPM
Power Max: 121.2 W
Power Avg: 81.8 W
Efficiency Max: 58.8
Efficiency Avg: 37.8

any help, tips?

I think the orion motor is 'torquey' in nature rather than a 'rev'er' but i'd start with a ratio around 6.8 (from memory for stock) and see how you go, they do run hot!
