What gear ratio should use on XXX-T Matt Francis 1 ?

[Quebecois_Sti]

Hello,
what gear ratio I should use when I will have my brushless combo ? (MGM Compro 80amp with Feigao 8s) I will use it with 6 cells and sometimes 12 cells and in the future 3s 11.1 LiPo. My gear ratio of my brush setup is 22/86.

thx for help

I usually recomend gearing the 8s similar to a 12 turn motor for the applicable vehicle (starting point). If you go to the 11.1 volt LiPo setup, I would drop a tooth or so as a starting point. You can adjust from here, but this should put you in a safe starting range.

and for a 12 turn motor what is the gear ratio I dont know... i am currently on a 19T chameleon.

Do you have the manual? This information is usually listed in the manual.
