Thanks all for the comments… So it appears the consensus is that I need to gear down, specifically the pinion. That said and according to BrianG’s calc, a 51/16 combo with my setup results in a whopping 32mph. That’s pretty pathetic for a brushless lipo setup no? Don’t get me wrong, I agree a 7xl is not a suitable motor for my setup, never was intended to be permanent, just testing BL (remember I’m a nitro convert). Dropping all the way down to a 16t pinion will allow me to do instant back-flips, but at the cost of being beaten by a stock E-maxx at top speed. To be honest, I thought the 51/20 was too low geared for my taste
