Motion RC parts and service
I am just getting back to RC airplanes after 30+ years away from the hobby. Things have changed so very much from the days of nitro fuelers, and the electronics at the moment are a nightmare for me. However Motion RC has made a lot of understanding a lot easier to contend with. The parts etc. I have ordered from Motion have always been received on time and have always been in good condition. and working properly according to specs. I have been using their write-ups a lot and find them very helpful, especially when it comes to the electronics and connections. Thank you MOTION RC. Ken J. Bird
The motor is of no use to me as the motor shaft does not allow use of Collette for propeller. Shaft goes out back of motor.
Just got my latest order from Motion, and as with all the other things I've gotten from these guys it measures up 100%, both in delivery and quality of items. Thanks once more.
Dynam Brushless Motor

THIS WAS A REPLACEMENT MOTOR
I had purchased a red Dynam Waco back in Nov. and after a few personal mod's she has proven to be a real show stopper at the field. HOWEVER!!!!!!!! it sounded like a coffee grinder (motor that is) when it was flying. Well, after about the eighth time of flying her and this noise just was not getting any better I called motion and talked to one of their reps about my situation. (Mike I believe) It didn't take long and he agreed that a replacement motor was needed. He sent one out to me, (free of charge) and ever since then, not only does the plane look good but even sounds like a winner. I believe for the $$$ this little motor, with the new Japanese bearings, is really a great improvement over what the original motor was and is. If you need a replacement motor, in this class and size, then this is the one.
