Horten Bros Ho-229...in "Five Easy Piece"

Here is my attempt at the Horten Brothers Ho-229 flying wing.

Wow,
That is a cool start, how are you going to control wing tip flutter?

I like flying wings so I will be watching your progress.

I plan on doing one with an EDF.

Thanks. It's pretty rough right now.
I was thinking about an Single 70mm EDFb too. But will most likely do a mid-prop setup.
I've been using KFm4 airfoils with CR on the leading edges and across the center in an 'A' frame config on my B-2 and PAK DA flying wings. My aerial cam vids with my B-2 have not revealed any wing tip flutter. I have seen the whole back-end of the B-2 flutter at high speeds and in heavy winds a lot though.
If you like flying wings check out my threads on the B-2 and PAK DA flying wings.

The powered version takes shape...
I have completed the build and tested the gizmos as well as loaded the wing and tossed her heavy for the final glide tests.
And now for the maiden flight...

Thanks Chellie.
I'm glad you like them.
You might want to try the "5EZP" Ho-229.
I think it makes a great flying wing.

Found these drawings of the flying wing from "Raiders of the Lost Ark" and began wondering if I could make this one fly?

gramps2361 10-19-2013 02:58 PM

With the cool wings you make, and the work you put into them to get them flying good I know you will. Looking forward to seeing what you come up with.:)

Crashed the NAZI Raider…into my right leg.
Broke the wing. Only thing holding it on was the CR and some HG. Tossed it back up and it flew with a wee bit o trim to the left wing.

Lost my 95 year-old Dad in December.
Haven't had much time or interest in building anything since.
When I do, and I will, I'm thinking about doing the Horten Crescent wing.
Notice how much the Horten wing looks like the UFO Ken Arnold saw over Mt Rainier.

Sorry to hear about your Dad, 95 years old, Wow, He lived a long life, He was given the Crown of Glory :$ My father is 85 years old and still going strong :$ I will be 60 this year, and I am Grateful to still have Him and My Mother around, Looking Forward to your Horten flying wing build, Take care, Chellie

I know I said I was going to retire her but like a faithful old dog she keeps jumping in the truck when I head to the flying fields.
Here is gray sky flight over the Meadows field from last week.

It's good that you still have them to look after. I turn 60 myself next January. My mother passed away when I was 15. My Dad was very special to me. You might say he was my hero in many ways. He was jack of all trades and never knew a stranger. He always understated his abilities. A strong, gentle, and sentimental man. Women just loved him. I miss him every day.

dahawk 02-07-2014 04:48 PM

Sorry about your Dad. I lost my Dad a few years ago at 88. Sad to see this greatest generation go. I did get to spend a little time with him before he passed on and it was funny how he liked to talk about his Army Air Force days and his B-24 Lib crew. He was a Tech Sarge.

Growing up , he rarely talked about it but near the end , he talked about his wartime experiences a lot. I think many of those who fought in WW-II suppressed a lot of feelings and many probably had some post war trauma that just never went detected.

He could MacGyver just about anything and despised the throw-away and replace culture that evolved. Taught me a lot. I can still hear his voice when I'm doing a home repair: " David ?" - "You're about as useful as an ashtray on a motorcycle " -LOL

Great Americans

Actually it took two hours to build the glider once I had developed the pattern.
No guts no glory.

It'd been even nicer if he had shown the plane before he launched it. Very few flight videographers seem to realize just how tiny and hard-to-see their models are when taken from the ground without the use of telephoto (which would take a really really skilled videographer!!).

That was fascinating, I knew the winglets reduced wing vortices, but I always thought they did so by acting like a dam, not actually creating lift of their own! Didn't quite understand how this worked when they were horizontal though...

,
Yeah, I got no guts at all, I test glide over the softest grassiest slope I can find! (Cluck-cluck, Buk-awk!):Q But then it takes me a little longer than two hours to build one too.
