Just visited the VarioProp website and it looks like they are done testing. According to their site, we are good to go on at least some of the blades for gas (and I assume glow) engines. I personally am interested in the 3-blade 16D hub with the 16.6" blades (good up to 6500 RPM on gas) for the RCV 60SP. However, I'm having trouble figuring out what I need to make it fit the shaft on this engine. Can anyone else figure out from the VarioProp website what would be needed? I also want to use the scale spinner dome.
