Need Himark / Cermark 480 (400 long can) motor information
 

I am building a Scorpio Miss Acro and I just bought MPJ speed 400 3:1 gearbox with extra 3.5:1 pinion and APC 10x7 prop.
I have a spare Graupner speed 400 that I might use. My LHS sells Himark 480 motor that has the same diameter with speed 400 only longer. I can't find any information about this motor. It's a cheap motor, costs less than Graupner speed 400.
Can anybody tell me if this is a better motor than speed 400 and will my 20A esc will be able to handle it.

Apparently Himark 480 is the same motor with Cermak 480.
