Stryker mtr brgs

[Peter Stapleton]

I'm looking to replace the bearings in my stryker F27Q 480 motor.
After a few bad launches with the motor running in the dirt with a broken prop, it needs new bearings.
I took it apart and cleaned and oiled the bearings, but they're still rough sounding.
My motor is drawing close to 50 amps.
The wavering, battery low sound comes on right after launch.
Is there a source for new brgs?
I can take them out a go to a bearing supply place and try to match them up, but it would help if someone new the bearing number?

This is a really fun little plane, the flat spins are so fast you can't count them!
