Horten Ho2-29 fighter bomber special

Always been fascinated by this plane, anyone seen the Nat Geo special on it yet?

Would make a really sweet ducted fan electric..

Check out my friend Gary Hethcoat's thread at RC Scale Builder. He built a the cockpit mock-up and models for the film (I don't get cable and don't know if they used the models in the film). Unfortunately you have to register for the site but it's worth it and they do not abuse your data.

I assisted Gary with the canopies for some of the models.

The HO229 is a challenging EDF subject but it can be done.

Is it flying? A buddy built an Ho V I think it was, and it was way cool. Tricky in turns because if you slowed it down the inevitabl happened and you got a wicked spin stall, but if you kept it moving it flew nicely. Only thing that was difficult about it in stable flight....with no vertical surfaces and a high aspect ratio, seeing it well at any distance was tricky.

They were so far ahead of their time. Alien technology?? It looks like a stunt kite.

Just some brilliant engineers with their backs to the wall.

You have to admit about this article, there are some pretty whack-job claims about this plane not supported by facts.

Could have won the war for the Germans? By 1944 if this had been operational, even though it's radar signature was 20% less than a similar sized plane, it wouldn't have been allowed a 100% increase of not being detected while en route to Britain. Plus the Allies already had their big offensive warmed up. This is just more Luft '46 pipedreams.

Local and national electric guru Keith Shaw built an EFD of the Ho 229 many years ago....as in back before lipos and brushless motors were part of the R/C world. If I recall be even scratch built the fans. It was an amazing model.

Goat, check out Gary's website www.wingsontheweb.com

It is most definitely flying.

He and I have kicked around the idea of a slope version but I just can't seem to get the building board cleared.

Ooooooh......*very* nice. But I still love my Me-163 Komet tho. What a great plane. Been toying with the idea of a rocket powered conversion for it for way too long now...

I saw the special and thought it was sensationalistic, exploitative BS.

Anyone who knows anything about the Horten brothers knows that the shape of this plane was for aerodynamic purposes, not stealth. That was not their intent. Basically, they -- like Lippisch -- believed (correctly) that they could build a lower-drag aircraft by dispensing with projections that cause induced drag. The fact that eliminating these projections decreases the radar signature does not mean that's what they were trying to do.

What they WERE trying to do -- and largely succeeded -- was to create a fighter that -- using the same engines and armament as the ME-262 -- went 60 mph faster. It would not have been able to fly undetected to England, but it would have been far more effective than the ME-163 because of: (a) its much greater endurance; (b) its heavier firepower; and (3) its use of conventional landing gear and ground support facilities.

However, it would have still suffered the same reliability problems that plagued the 262, except that maintenance might have been even more difficult because of its recessed engine installation compared to the nacelles of the 262.

BTW, the first Stealth aircraft could be considered to be the Mosquito, which had a reduced radar signature not because of shape but being made mostly of wood and fabric, so basically only the cannons and the engines reflected radar. But that was not why it was made out of wood -- it was to conserve higher-cost strategic allloys, and the same was true of the Horten.

The 262 was the real deal. And again, despite all the hoo-hah about Hitler delaying it because he wanted a bomber (easily circumvented by making it a fighter-bomber), the REAL reason for the delays were the engine problems which were never fully solved. Had they been -- and if Germany had the oil and experienced pilots to exploit its potential -- the 262 would have cleared the skies over Germany and lengthened the war long enough to get the Nazis' butts nuked in late 1945 or early 1946 by B-29s escorted by P-80s and/or Gloster Meteor Mark Vs (600 mph, 4 20mm Hispano cannons).

John Greenfield here in the UK built and flew a successful large twin turbine model - the mixing was a bit of a nightmare - drag split flaps for rudder authority and so forth - was a pig to land and put the gear up through the wing more than once but flew very well!

They were even further ahead of their time than you think. The brothers were building full scale flying wing gliders in their parents house while they were still teenagers.

Way cool. The kit says drag rudders, I wonder how well differential thrust would work?

I think it would be a little stinker to fly, mostly because of orientation but it would need a great deal of speed as well.
