I definitely would love to be there for the "Maiden"..!!!

are you going to do all linkages internally so nothing can be seen on the out side

The rudder will be 100% internal, the elevators, and aileron will have only little arms sticking about 1/4" out the bottom, I need a specific moment arm to get enough travel with the torque I will get from my servos. Unless you look real close I don't think anyone will see them.
Thanks, DAG

This project is about as amazing as it gets. dag, have you always had an incredible aptitude for complex projects? Are you an engineer for a living as well if you don't mind me asking? Really quite astounding. I can't imagine that there is an aeronautical engineer out there who wouldn't be quite impressed with this endeavor.

I'd love to see this plane fly someday. Will you take it up to Muncie for demonstration flights during the NATS or at other events? I'm sure we'll see it on youtube, but it would be so cool in person.

Thanks for the wonderful comments it is really great having all the support from you and all the others.

I have been e-mailed by many asking what I do for a living and have I worked on aircraft design and also if I am an engineer. The truth is I barely got thru high school, it was just not fun, and never did the college thing, just seemed to slow, heck I can barely spell correct. My bill paying job is I support and design the hoist systems and controls (computers) that you may see in a theatre or in Vegas. The huge sets that weigh 10,000 and up to 50,000+ pounds are moved by the systems I support and help design.

Aviation has always been a hobby. But I have to be honest, I have seen some real aircraft engineers that are clueless when it comes to thinking in 3D design.

Thanks, DAG

Oh come on, internal belt drive the surfaces (or something similar). Based on what you've done here, shouldn't be too hard for you to work it out

I know a brilliant young man who would wholeheartedly agree with you. He designs full-scale flight simulators for aircraft and helicopters. He recently mentioned to me that it's hard to hire additional engineers to add to their team because so many applicants just can't think of a problem conceptually. Or they don't, anyway. They can work out calculus problems like you wouldn't believe, but are unable to offer suggestions that are really useful in taking an engineering challenge to the next step.

This is wickedly Brilliant! bravo!

Dag,

Funny, I saw the road cases in one of your pictures and wondered if you might be in the biz, I was a lighting designed in a previous life ;-)

Do you happen to have the wing area handy? I created a profile in MotoCalc and I'm trying to be as accurate as possible...

I calculated 5,311 sq. in. if made to scale, am I close?

Thanks,
The Sq" are 5,425. I am not including the tips as they produce about 75% less lift.

And the true Kv of the motor is 168rpm/v

Thanks, DAG

Very close. Not sure why we are off, but I did calc true square inches, not just the foot print. I calculate buy the true surface area.

Thanks, DAG

Mine was a down and dirty percentage of original wingspan to yours, trust your own!

Here's what MotoCalc shows, impressive thrust Dag!

Looks good,
If your prop calcs are correct the Zinger is doing better than I thought. When I use E-calc it shows max amps at 48ish, and max thrust at about 60 pounds. Not sure why the 2 differ so much, but heck I still think she will fly. Also once I see how she flies I can then cut down the high trim on the throttle.

Thanks, great info.
