Going 5 cells, what motor?

[tobbe]

Hello mates!

I'm planning on going 5-cells this season in my B4 and Predator. I'm currently running 6 cells and a Novak 6.5R turn motor in my B4 and it's really fast. But batteries are quite expensive so to keep the cost down I would like to go 5 cells. The question is, what motor should I go for in my B4 and Pred? I tried my 6.5 motor in B4 with 5 cells but it was quite slow and accelerated really bad. I want to have the same performance as with 6 cells. Would a 4.5 or 5.5 be a good choice in the B4 and a 4.0 or 4.5 in the Pred?

Regards Tobbe
