Jammin X-1 CRT motor selection

[glassdoctor]

You do NOT want the hot motors like 6xl or 7xl... especially on 6s lipo!!

I think a 9XL is the motor you should run. 50mph would be easy on 6s which is your target. 50mph on 4s would need a very tall gear but could do it if you really want to... 16/46 gearing would be around 45mph or so.

For 6s I would actually go lower... 10-11XL

here's the rpms at 21v for reference:
8XL 41400
9XL 36800
10XL 33100
11XL 30100

30K is plenty.... my truck/buggy run under 24/27k and they do 40+ easy
