Budget intended conversion

[Arct1k]

Honestly we have all been down this right but you are much better off with saving your money and doing it right the first time.

Buy a MMM combo 2200

The MM will require an UBEC to work on 4s whic basically gets you to a MMM. A feigao and a heatsink (unless used) will get you to a $100 which is close enough to a castle neu.

If you are looking used then thats different...

Why cant i use the hobbywing esc, y does mike sell the hobbywing one if people r saying its junk, i read its great? Now what medusa motor on a 4s setup? If not I will go with the speed passion or novak combo!!!
