ha ha slowly i haven't touched it since i started the springer which I'm almost finished .. only the control room to build , rudder assembly and prop then paint and detail, its a "xxxxx" waiting for parts to arrive but lucky springers are a nice little pass time .. check the springer pages for my post , I'm about to do it now.
have you looked at actions site what motors they stock?
you may be looking at a 25A for the 750 , not sure maybe a 40A, check the motors draw before you buy an esc.. the Action website stocks the esc's cheaper then the mtronics. just a matter of choice i know i will be spending best part for £150 with Action just before Xmas for the huntsman.
I'm using a mtronics eco 27 (20A) for the springer thats going to have the 600 motor from my IC buggers starter system ( sold buggy to fund boat builds) very torque motor should give the springer a nice push, running on twin 7.2 Lipos in Parallel if thats any use to your setup might be of intrest, I'm still deciding what to put in the huntsman but I'm drawn to the 700 BB's don't ask me why
