[Savage04]

I want to put a brushless system in my micro rs4 if possible and i was looking at the mamba max 25. will this system fit and if so which batterys would you guys recommend. i have never had a brushless and im new to the brushless world but have been doing rc for 10 years now. so if you guys could just gimme some tips on which batteries will work and if that brushless system will work??

Thanks
