Counter-rotating twin engine planes - reverse prop adapter?

[Hoomi]

I've been thinking about building up a foamboard twin engine plane, and the prototype had counter-rotating props. I looked at the prop adapters in the FT store, but didn't see any listed as having the reverse thread so that the torque of a clockwise-rotating prop will still tend to keep the prop-nut tight. Is one available? Or do we have to use some other method to keep the clockwise pitch prop tight?

You just use a Nylock prop nut. They don’t come undone. If you haven’t got one of those then some blue Loctite on the thread will be OK.

A little german torque doesn't hurt either...
