Thanks, sent link to my hubby, but he will probably just say “No big deal, I ordered it yesterday”

[GeronL]

sounds cool. Get one before they banned. lol

[Lmo56]

Found a better video - shorter, but you can see more ...

Is this for real or a hoax? It seems like it would be impossible to control something doing 400mph like that. Plus if it lost control, it would be a pretty deadly missile. That being said, where can I buy one?

Wanna see something even faster without spending $4K on a turbine jet? Check out “dynamic soaring”, a phenomenon in which a glider uses the differential in wind speed between the windward and leeward sides of a ridge to accelerate to phenomenal speeds. Over the last few years pilots have kept increasing the speed and they are now approaching 500 mph. Check out this and other videos on YouTube.

I could scare the crap outta people with one of those things!

WHERE CAN I GET ONE?

[Bullish]

I’m thinkin’ the controls might be a lil’ bit touchy.

Can you imagine if terrorists strapped a couple of pounds of C-4 to that thing - its so small and so fast NO ONE would be able to shoot it down before it hit its target ...

[Ron C.]

I built and flew quite a few gliders - many flown in Gorman, Ca hills at speeds of 250-300 mph most days. Only one thing about that - a lot of the earlier ones simply 'blew up' - traveling faster than the build would tolerate. It took a long time to design one that would hold together at such speeds.

But, I had the most fun with a big slower craft that carried a camera to take pictures of the falcons, eagles and condors that often came up to fly playfully alongside.

Damn-

speechless.....

[advertising guy]

you have a small mind

imagine addin a Red Ryder B.B. gun in the turret

if’n you’r any good, you’ll put THEIR eye out

lmao

[Lancey Howard]

This is really cool.

[Pecos]

I’ll be polite, and not simply call “BS”. However, I do have two basic questions for the actual aerodynamicists in the group. First, how does an aircraft with straight high aspect wings survive those speeds? Isn’t this in the realm at which WWII fighters began to have structural and aerodynamic failures? Second - a hand-held radar gun that accurately measures 460+ MPH? Really?

I would appreciate some concrete references, rather than expend all of my credibility points.

Isn’t this in the realm at which WWII fighters began to have structural and aerodynamic failures?

Many WWII fighter aircraft reached speeds in excess of 400 MPH. The problems didn't occur at those speeds but at the speeds obtained during dives, in which the planes approached the speed of sound. The P38 was especially prone to having the controls lock up during high speed dives.

The P38 was especially prone to having the controls lock up during high speed dives.

The phenomena was called "compressibility".

[central_va]

I think the speed of an rc aircraft should scale to the size of the aircraft. This thing is to fast, just a blurr. What is fun about that?

[calex59]

Yes, I know. Must have been scary to the first ones to experience it, or even the later ones:)

[Artem55]

High aspect ratio wings are no problem these days with CNC molded wings of carbon and kevlar. Still, I have seen more than one video of a ship simply exploding in mid-air from flutter. Extremely tight linkages with no slop are a must.

Do a little research on the subject. You will have to take up your argument with the PhD's in aerodynamics if you still have doubts. Here are a couple of links to get you started.

Thanks for the references.
