Rnr107,

I just removed the shaft yesterday on my Turnigy G110 outrunner motor, so this is specific to my motor, others will vary...

1) remove the 4 M3 screws from the propeller mount.
2) remove the e-clip (circlip, retaining clip, however you want to call it) from the side of the motor with the shaft sticking out.
3) pull the shaft out by hand (I've heard you may need more force on other motors)

That's it! I really like the G110 for its simplicity in this manner, though it is a little pricier.
