Hello and good Morning,
A question,
The scope of delivery of the motor mentioned above includes the locking nut, because the propeller doesn't "slip" under load or is it only really tight with the nut?
And what is the best way to hold the engine bell when tightening the lock nut?
So far only had experience with self-locking propellers. 
Here's another picture.
