Huge Model Plane!
 
This is sooooo cool! I love the way he side slips it in for the landing!

woohoo huge indeed !! sounds nice too !

"Avoid slip with flaps extended" ;)

On the fly-by with the ramp estended, I kept expecting see a drogue chute come out with a small pallet attached.

Wonderful job!

That thing could fly a small child!

I thought the exact same thing:)

Thanks for posting...that thing is really something.

Hmmm. You just made me want to build a small turbine powered personal aircraft. How much thrust do you think you would need to pilot say, a 200lb person. Now that! sounds like fun!

dd74 12-15-2008 12:33 PM

Very cool. Is it easy to find the little turbine engines for that plane?

Pretty easy, just need a lot of $$.

I bet you could find a BD5J airframe pretty cheap. hehe;)

How in the heck would you get that thing to the field to fly?

Its dang cool btw.

stevepaa 12-15-2008 01:38 PM

amazing!!

targa911S 12-15-2008 01:57 PM

WOW! That is so cool!

svandamme 12-15-2008 02:00 PM

looks like it has plenty of thrust/lift to take children for a ride...
20 bucks a pop, every weekend... 5 minutes each, let's say 100 a weekend

That's not bad money

rattlsnak 12-15-2008 04:54 PM

very cool,...

A prop plane sounds pretty cool as well...

Wow that was cool. I was in the hobby industry for nearly 8 years and never really saw the ducted fan units work so well. I guess they have improved in the recent years. It is amazing that thing can lift off the ground.

Nice video. Thanks for posting.

Those are turbine jets, not ducted fans. :) Ducted fans are a thing of the past.

NAw - they just do it electric like now. MUUUUCH better.

they don't sound electric, they sound like turbine jet's...

Ha! Mike is saying that ducted fans have gone electric - which is true.

The C-17 does run on turbines.

svandamme 12-15-2008 10:51 PM

4 RAM 750P's to be precise

slodave 12-15-2008 10:57 PM

You only get about 25 hrs. before maintenance, sounds like fun. What's involved?

Craig 930 RS 12-16-2008 07:55 AM

$16,000 of engines whosshing by....wOw.

It'd be slick of they dropped a dog rigged with a parachute - out the cargo door while in flight ;-)

Precisely - Ducted Fans are still around it's just that they are electric powered and believe it or not they do have a sound all their own.

Glow Ducted Fans were just irritating sounding but electrics sound a lot like air moving but the fan also makes quite a pitched whine - like a much less throaty turbine (or a turbine with no balls if you will).

Small EDFs are extremely popular.

Do you realize that you are looking at about $14,000 worth of model airplane?

Each of those tiny jet engines are about $3000. Multiply by four. Add about $2000 [probably fairly conservative] for the airframe, and you get the idea.

-You don't "slip" a model airplane. Nobody is capable of looking at a small aircraft like this approaching at probably 50 mph and properly slipping it. Most model pilots hook up the rudder, but few use it because it is almost impossible to use it in a way that helps you. Model airplanes fly like house flies-they are VERY quick and constantly moving, and this fact makes them enormously [!] difficult to fly. How difficult? I consider a model airplane with a 50 inch wingspan 4 times more difficult to fly than a Boeing 747. I have spent years flying model airplanes, including Quicky 500 and Open Pylon racers. AND I am type rated on the 747 classic and have 1500 hours of experience on this plane, much of it as Captain.

heh! Model airplanes are the most unforgiving aircraft in existence. Ridiculously difficult to fly, the only sane model airplane owner in my view is one that hangs his planes from his den ceiling and buys a good model flight simulator. That guy that built that C-17 with four jets? He's either a billionaire or his wife puts on a bunch of leather and spanks him good each night cuz folks he's pretty much into pain!

N!

That was a Caravelle, it happened in Africa from what I heard. The guy lived- that engine is a JT8D-7, and it has a set of vanes about 8 inches wide that guide air into the first stage of the compressor. In this case, they were like the grates on the barbecue grille; they kept the meat off the fire!

of course...he caused that fire by blocking the air flow with his body. Idiot! Didn't it occur to him that an engine with an air intake 44 inches wide might not be the best thing to be in front of when it began to start? Engines this size tend to eat a lot of air....

N!

cgarr 12-16-2008 05:49 PM

I have a J3 Cub 72" wing, used to slip it all the time. In fact I hooked it up with extra rudder just to get a good slip out of it.

That was sweet!! I wonder if these builders get movie parts because of how realistic these aircraft look in flight?

Here is another one, kinda long but shows a scale model of a Raptor in flight.
Oh well...who needs advanced avionics to keep this modern day fighter stable in flight :D

Where I fly regularly (The Sepulveda Basin in Encino) we have a very high population of turbine fliers.

They crash fairly regularly and during the warmer months they do tend to provide practice for the local fire department.

In SoCal turbines have been banned from just about every other model field except ours due to poor judgment and fires.

Here is some turbine fun:

The real C-17's are built right out of long beach airport. I clear them for take off all the time. Sure seeing a model of it fly is cool, but watching the real thing is pretty awesome! In the first video where it does a low approach and then goes 90 degrees straight up...yeah they can really do that. I've seen them. Here is a C-17 parked right next to our tower.

There is a really big model airport just outside of Livermore on the Tracy side. Does anyone go there?
