Hello all,
recently I talked to [link]http://ramoser.de[/link] who make adjustable props for electrics. They upgraded their production line with bigger props, til now only for electrics. BUT they test the props for use in combustion engines and do believe to have some results in July. Some of the smaller diameters are already allowed for combustion use.
The system is similar to the soloprop system, aluminium hub with separate blades. 2 - 4 blades, scale blade shape.
Since there is a lack of scale props with suitable dimensions on the market I guess this are good news
regards
Andi
