Turnigy to a "BRAND"

[rutt]

evening all.
Im currently weighing up a new motor.
I have run turnigy motors since returning three years ago.
currently use a 6.5 in an XB4.
There is plenty of speed but am struggling low down out of hairpins
Has anyone experienced going from turnigy to say a reedy or hobbywing.

I've tried a bit on the speedo settings but it just turns into a nutter on the throttle

thanks

paul
