RE: I'm replacing glow with gas. Need some advice.
ScottM, I replaced an OS 120 FS with a DLE 20. The OS turned the 15-8 three blade Graupner prop at 8,200 rpm. The DLE 20 turns the same prop 8,600 rpm. The DLE also seems to have more torque. There was a total weight increase of about 5 oz. I could probably lower the weight by going to one li-po and regulator instead of two Nimha batteries.
