nitro to brushless

[uarghhh]

hi guys! first, I'm from Quebec... and english is not my main language so.... be kind :)


I'm about to start a brushless conversion... The truck is a 4wd crono prima.... and I really don't know where to start... I need advice/help... I have remove any nitro stuff in the car.... Now I surely need to calculate the ratio to see what kind of motor I will put in..... For the cell, I think I will go with a123 cell.... I want a cell that is safe, I had some bad experience with li-po in plane...

So, If someone could help me out to start... some advice on motor and controller.... Thanks

Julien
