hey guys...wanted to say hello, and say this...power to weight ratio is relative to wing loading. A high wing loading and high power loading make for a marginal plane.

My 3 pound foamie jets like the LX F-16 like 1000 watts. fly marginal on 750 watts. I suppose fan efficiency is very important. WeMoTec fans are very good efficiency. The HET Fan is rather good too. I'm trying a new one, from Extreme RC in Australia, a China "Skyworld" 70mm cast alloy and 8 blade rotor. The rotor is frp or cfrp ? and has a turned alloy spinner, nicely balanced, hard to improve upon.

As soon as I've used the fan in a plane in actual flight I'll post more info
