RE: NEW DLE 20cc Gasser! (Data & Links 1st Post)
I ran my dle 20 for the first time last night. I ran my old 14x7 3 blade just because I had it and wanted to see how much more rpm I could get over my last engine, the YS 91 FZ. The YS peaked the prop at 9300 rpm. The dle was peaked at 10,500 rpm. It was screaming with power. I bought a 15x7 3 blade to try out and I am wondering if I should have went with a 16x8 3 blade. Master Airscrew brand, just to be clear. This engine was incredible right out of the box. If anyone has performance data on the 16x8 3 blade master airscrew please post numbers. I am wondering if I should bother with the 15x7 as I really need a static rpm of about 8500 on the ground. Appreciate any data or advise.
