Ospray ?
 

Does any one know where I can find a article on how to build a electric version of the VTO Osprey?

RE: Ospray ?
 

I don't mean to rain on your parade, but unless you're an aeronautical engineering student with more time and money than brains, find yourself another project. The dynamics involved with an Osprey are so complicated that even the Government has given up on the project. (And if anyone has more time and money than brains it's them!)

RE: Ospray ?
 

IF there is a successful full function VTOL V-22 RC model out there, the owner is keeping it very secret. Search around here for !QUOT!Vertical!QUOT! and you'll find threads of like minded folks. Also I believe one of the US RC magazine plans services has an auto-gyro disguised to look like a V-22 in rotor borne flight.

Agree that a V22 project is beyond the budget (and current technology) of most RC builders. :(

However, I believe the government is proceeding with development (check out http://www.boeing.com/news/releases/...se_990119o.htm) which I think is a good thing.

Tilt rotor technology is the next step in aviation. It will be developed, if not by us then by the Europeans or Japanese... I would rather be in the lead when this technology is ready for market.

Here is another link to the Helicopterpage.com that details V22 development and history - very informative for V22 fans (which I am unabashedly) :)

Thanks for the info and the program will be no longer in my mind.

There's actually a group of people working on a vtol kit. Sorry, but I can't find the link now. Click on this link and scroll towards the bottom of the page. There's a video of a home made vtol, featured in MAN a while back. [link]http://www.radiocontrolzone.com/plane/video.asp[/link]

I found the link I was looking for, but its not an Osprey. Predicted available in 2005. Priced at around $1000-$1500US. Here's a small thread about it [link]http://www.rcuniverse.com/forum/m_1339382/mpage_1/key_vtol/anchor/tm.htm#1339382[/link]

The real one doesn't fly, why would you think the model would? ;)

RE: Ospray ?
 

3D, why are you making this statement? The V-22 is a good aircraft. Yes, the most advanced aerodynamics technology ever put in to production has had developmental problems, that have sadly caused loss of life. But that's why they're called test pilots.

So why do you think it doesn't fly?

The real ones do fly :D The Navy & Marines use them. Since its conception, they've made great advances. I've also seen them a lot on the Discovery Wings channel. Here's the Boeing link for the Osprey.

The home made Osprey, video I mentioned b4, doesn't look like it has tilt rotors. The other I mentioned is a "harrier". Those have been built b4. Just do a search here on RCU for VTOL.

Me thinks you give up too easily! :)
Take a look in the unusual RC section, there's plenty about the Osprey and other VTOL aircraft.

With electric motors it should be easier than with engines if you can get the power to weight ratio. My approach would be to forget the cyclic too, that and the gear to connect the engines (which you don't need with electric) is what causes all the hassle.
Just treat it like a twin and try some test flights with the engines facing forward. Then experiment with turning the nacelles to achieve STOL flight. You probably won't ahieve a perfect hover though as that's where you'll find the stability problems.

It was a joke...:eek:

RE: Ospray ?
 

Sorry to rain on your parade Minn flyer but the Osprey V-22 is now in limited production. The project was never dropped just delayed by development problems. It's only been a few years since we could hardly imagine turbine model engines but they're here in force right now. For that reason I will not say that a model V-22 is imposssible but at this particular time still in the developement stages. I may not live long enough to see it but I'm quite sure some of the newer modelers will.

RE: Ospray ?
 

I respectfully disagree... The V-22 is new technology which is being developed in a very detailed flight test and develpment program. FYI, it has an accident rate very similar to other aircraft that are far more conventional - check out the links I included above.....

Cheers!
