I was just joking about the price. All of these are very inexpensive.

I'm pretty sure that the prop saver can be removed from the Dynam motor leaving a shaft the same length as the SR's. Spec's on the motors are identical.

The motor you linked would not work well for this application. Notice it's KV rating of 740?
It will not spin the prop fast enough to provide adequate power. This motor would require a larger prop or higher V battery, neither of which can be used in this plane. You need a rating near the 1050 of the stock motor.

This one would be appropriate:

No reason to change the ESC. But because the motor does not have a threaded shaft you would have to use a prop adapter.

Here's another good candidate from a reputable supplier, adapter included:
