It may well be worth contacting Menz in Germany, they were very accommodating when I needed a L/H 26 x 12 prop for my Tiger Moth. They made me two custom props and didn't print their brand logo on the props, to make it easier for me to finish them. Ask them, all they can say is 'no'.

The constant and cyclic flexure and vibration of the prop blades when the engine is running and transmitting power would eventually lead to glue line failure and delamination and disintegration. Even model size props, and this is for quite a large scale engine generating considerable power, flex a lot when running They're quite okay just an ornamental prop though. Trevor I never thought of that, thanks for the warning, Trevor. Once again proving a little learning is a dangerous thing Regards, Rob
