I found my old 7XL in my 'junk' box, so I decided to give it a try on 6s lipo, G3 lipo that is. The only pinion gear I could fit on it was 18T, so 51/18 on orig. GM single speed tranny, geared a 'tad' high (75+mph)

..... HOLY $#!T

I could NOT use anything over 70% throttle for more than .2 seconds, the thing was literally almost going to fly apart! I can't even describe the power it has.
Video for tomorrow!
