juweeltje, I've been running a three blade Xoar 18-8 on a G-38 in a ESM Hellcat with good results. Turning about 7,000 rpm and very little difference in power (as in flight performance) that a two blade 18-10. I think the DLE 35ra has more power than the G-38. I think the Biela 18-10 would be too much prop
