GTB Brushless TC4 Gearing Q/A

[tkRC]

I just installed my GTB 4.5 in my tc4 but i can't find any gearing advice if you have this setup please comment on it. right now i have 75 and 72 tooth spur and 14,16,20,21,22,25 pinion gears. Thanks for the help.

This is the second time i have asked this Q/ because the first time i had the numbers wrong.

I ran a 24/72 and it was fine. I had no problems with it getting hot eather. Worked great with the soft start. I had a 19/72 and it ripped the tires loose mid rpm and would just spin out. It still spun out with the taller pinion but only while slightly turning. Going straight I had no problems.
