Hi Paul, Thanks for your comments. You are absolutely right as not having to hammer the shaft out, but I did not have anything close to a drill press at my disposal. Thanks for the tip. I’ll keep this in mind the next time I dos such a thing.

I forgot to mention that the other reason to use a drill press or something similar is that the force being applied needs to be no greater that that required to start the shaft moving into the motor where as striking with a hammer applies a much greater pulse of force than necessary over a much shorter time period. You could also use a vice to press a shaft into a motor.

I don’t think it’s advisable to hammer a shaft in to the motor, there’s a good chance that the shaft may bend slightly. It needs to be pressed into position in a manner which ensures that the motor and shaft stay in alignment and the force being applied to the shaft is in line with the shaft. I use a drill press.

Sorry, I have no idea. But you can get a replacement pack for the accessories from hobbyking.

Great tutorial. By chnace, any of you have any idea where to find the bearings for this motor?
I have six motors waiting for them.
Thank you in advance

I used a nose plier. To put it back on, align the cir-clip on the groove and press it in with the nose plier. Home this helps.

Luc, that is a good idea! Wonder why I never thought about that.
Were you able to build what you were going for?

I just got my motors in, but why not just cut the axle on the bottom end ?
Mine have a piece sticking out the bottom, like in your pictures. Top end is OK for mounting the prop.
So I was just thinking, why not change anything, and just cut the bottom part with a dremel disc?
Thanks for the very clear instructions
