Thanks for the response Balsa Master. A flying wing needs significantly less power to fly than a conventional aluminum tube A/C. The entire ship has lifting properties none of the structure is just along for the ride. A conventional airplane has a fuselage and tail group that don't contribute to lift at all - these parts are "just along for the ride" so they require significantly more power for flight. Nasa built an amazing R/C airplane testing the idea of using a flying wing / blended wing lifting body as an Airliner. The A/C was huge maybe 18/20 feet span but the engine they used was a paltry I think 90 size 2stroke. I've seen video on RCU of this amazing Aircraft flying maybe someone will find it and attach a link. Thanks again for the advise. Deltatech[sm=cool.gif]
