what motor is a good engine(well thats stupid they both own)
Whats the pros and cons of each... of course the WS7 is the cheepest.
Whats the diffrence of the WS7II over the WS7?
Would it be worth going with the C5?
Are they semi easy to tune and relible motors if broken in properly?

I currently have a RB EFRA 9863.... good enough or no?
Thanks again
