Emaxx questions

Thanks, i emailed him. Hopefully the transmission will hold up (with a couple of modifications) until the single speed conversion are available again.
Also, i used your top speed calculator, and with the 8xl, 18/66 gearing, and 12 cells it shows a top speed of 26 mph. Is that really all its gonna do? How high of a pinion number can i safely put on there?
To get 40mph, i would need 14 cells/4s lipo and a 24 tooth pinion.
