Almost finished with my 80 inch all nomex composite batwingp-180 poweredhere are some pixprototype flew well

very nice, keep posting your progress

Just seen your interview kewl http://www.youtube.com/watch?v=uWcpY9cg1o0

Glad to see you're back at it with the Batwing, Rick! How does the intake ducting work on a design like this? I have no experience with turbines, only small EDFs (70mm). From my experience, proper intake ducting is just as important to the efficiency of the EDF as the exhaust ducting. Is this less important with a turbine?

Also, we will see a detailed cockpit with appropriate pilot figure...right?

That thing is amazing looking, How many hours are into something like this?  Looks really really good...<div>

Your right about the intakesThe size of the model was determined by the intakes and exhaustat 80 inch span there was enough area of intake to supply the chosen turbine for that size machine-r and the exhaust was also adequate

Required a whole year just to produce the moulds-working nights and weekends

Beautiful model! Are there any videos of it in the air?

Sorry to bring this thread back to life but I’m trying to contact Mr Hammel! I’ve designed and flown several semi scale batwings and I’m designing a larger scale accurate version. I’d like to find out some details about his flight performance.
