Did anybody that was running a DUO 2 which updated their motor find that the new motor had similar characteristics to the DUO 2, ie, found they were using similar RPM ranges or boost settings on the RS... motor timing on the can etc.. If so.. which motor?

I was after a 'newer' motor, but with similar characteristics to the DUO 2 just to help with finding the sweet spot with limited time to test/play. (Track is about 90 x 60 feet with a mixed infield)

Any one go from the DUO 2 to D3?

thanks

And I am NOT asking which is the best 17.5.. ok.
