Running a pusher in reverse

Running a pusher in reverse
Only a reedie can do this, unless you have the left turn crank for a TD. Is there any concern about this configuration? How likely is it for the prop bolt to loosen and everthing to dis-assemble in flight?
Reason I ask is cause I'd really like to use some of those 3-blade pusher props on a scale-type project, just in a tractor configuration.

Re: Running a pusher in reverse
The concern is real. Starting, in a prop strike, in a over compression reversal of rotation, if the correct torque is not applied to the prop nut... Yes, the reverse rotation prop can loose it fasteners.
Happily in a properly set up system torqued to the correct amount of tightness, the only real concern is starting and prop strikes. Those both happen on the ground. If the engine is running right I doubt the prop will come off starting. It takes a pretty good amount of force to loosen the nut/screw by striking the prop blade.
A ground strike will probably scrub the flight anyways.
Over compression is not going to happen unless you change something.
So go for it.
