I've flown many tractor and many pusher type planes with collet prop adapters and some with just a nut a washer holding the prop on and never had one come loose.

If your prop did come loose it's because:

1. You need to go to the gym, it wasn't tight enough,
2. You're using the wrong size collet adapter.
3. The props hub was too thin and the threaded part of the adapter bottomed out in the cone before it was tight enough. (add a washer)
4. Prof loosen it while you were in the port-a-potty as a joke, (He's bad for that.)

Don't blame it on the way the motor turns. The prop doesn't have enough mass to cause that, especially a 6x4.
