More info at http://www.jonshobbies.com/rebuild-of-an-e-flite-power-90-motor.html -- I had a hard landing with my Hangar 9 Twist 60. It wrecked the landing gear and the e-Flite Power 90's brushless motor's bearings.
I rebuilt the motor tonight in about 10 minutes and took photos. Here's the sequence to rebuild the Power 90 brushless motor with Boca Bearings. I had to order the bearings by part number, and they are the ceramic types. The Boca Bearing part numbers are SMR696C-YZZ NB2 (back) and SMR626C-YZZ NB2 (front). All is well with the world again and this is an easy fix.
I ordered the motor shaft and the prop adapters from Horizon hobby, but they didn't sell a bearing kit. I know the Boca Bearings are good stuff as I've used them as replacement in my helicopters for many years with good success.
