OK i've decided to remove the stock tranny completly, and put a center spool, with a custom motor mount.

The only thing i hesitate for now is which engine i'll put on it.

I want to run it on 6s, i will buy a Mamba monster max ESC, but for the engine, i don't know which one to take between a 1515 1750Kv or a 2200Kv.

And should i'am beter to go with a 1518 serie???

Thank you.
