View Full Version : 480B Outrunner Brushless Motor Shaft
09-13-2010, 03:25 AM
My 480B Outrunner Brushless Motor has developed a crack in the back where the set screw secures the prop shaft. I have attached some photos. Is there any way to repair this or do I need to replace the motor. The set screw just spins in place when I try to tighten.
Thanks for your help.

Throw it away and get another motor, the motor are cheap enough now days, but if that is a prop adapter, take it off and get a collet prop adapter to replace it with

480B... The PZ Radian motor?
I don't think it's repairable. Anything you try is likely to fail or throw the balance of the motor off. Unfortunately, they don't sell replacement parts to fix them. New motors are a bit pricey... $60 each.
I would search to see what others have done for replacement motors. I doubt you will find an aftermarket replacement motor that drops straight in so be prepared to modify things....
- Drill new holes in the motor mount to fit
- A new spinner/hub & folding prop to fit the new motor

A bit of digging revealed the following:
- Stock motor mounting uses 4x screws on a 25mm dia. circle
- Stock motor shaft is 4mm
- Stock motor weight is roughly 100g
- Stock spinner is roughly 50mm diameter

If you can find a way to adapt it to your mount (19mm circle rather than 25mm), this motor is roughly equivalent: http://www.bphobbies.com/view.asp?id=V450327&pid=B1898545
