MBX5T　pinion helf!
 

hello!
i have MBX5T
MM burnt with 15/46 (4s)the other day.
I ordered MGM16018 and 13T this time.
I plan five or six cells.
Is a smaller pinion better?

use the calculator for you desired maximum speed. I would gear for 45mph

wat motor are you running

sorry!
neu 1515 2700KV

That's a high kv motor for a truggy. I think 4S is the best voltage for it. 5S would spin it very fast, and 6S would be too much.

If you do use 5S, put a very small pinion on it.

that should be a good 4s motor but 5s would prolly give u alittle more runtime so I'd say 5s and gear it lower should I say gear it properly

Thank you for advice!
I want to test it in 13T now.
i have 4s(5300)×１　2s(5300)×１　２ｓ（４０００）×３
