feigao 8s motor with what speedo ?

Depends on how many cells you plan to run. A Feigao 8s would be very fast on 8 cell with any controller (ideally an MGM 80). On 6 cells I would recommend something more powerful like a Feigao 6s or 7s, or if you have the budget a Lehner Basic 5300. On 6 cells and a 6s or 7s don't use a warrior 7018, it probably won't be powerful enough. An MGM80/120 or warrior 9918 would be fine.
