I'm looking for props that fit an M2 shaft and are 26-32mm. plastic or copper doesnt matter.
think offshore sold a thing that made it possible to use M4 props on the zigzag shaft, wich I think is M2. Anyone know where I can find it cuz offshore doesnt have it anymore.

Thanks

Graupner has a 26mm prop with 2mm tread which is used for ECO class in europe, Offshore also has it:http://www.offshoreelectrics.com/products.php?cat=60
You can easily make an adapter by tapping a M2 tread inside of a M4 screw cut to lenght, it has to be done on a lathe to be concentric.
