From Model Airplane News:
An R/C plane’s first flight is usually a nerve-racking experience, but what if you’re flying a 16-foot-span, four-turbine-powered scale airliner?
Earlier this month in Oppingen, Germany, Adi Pitz’s 747-400 scale model took off with pilot Rainer Kamitz at the controls. The largest plane Adi has ever built, it has over 2,000 hours of work into it, so we can only imagine how nervous he was!
The 747 is powered by four Hammer Engines turbines, each with a thrust of 14kg, and it’s controlled by Weatronic radio gear. The 131-pound giant has sequenced landing gear and is 17.8-feet long.
Thanks to YouTube’s Kingschneidi for sharing this great video of the 747′s first flight!

Bravo!
And I thought soldering a slot car kit together was a lot of work! 
Cheers,
PS: It looks like each of those mini turbine engines costs $2,800.

I saw a FB video with another large R/C plane, and they showed it being unloaded.
They bolt the wings on, on site.

Yeah, but even with the wings removed, he'll have either one 16 foot section or two 8 foot sections. I couldn't carry them in my cars in either case.

There was wing stubs on the fuselage, so two separate wing pieces.
IIRC, it looked like they a decent size work van, like you might transport 4x8 sheets of plywood.

Kinda makes even a big slot car box look a bit wimpy, don't you think? LOL...

I'm hitting the road.
Google C17 R/C plane.
That one appears to be the biggest.

Zeppelin Hobbies in Riverdale NJ (home of the 1992 USRA Nats) for quite a while was big into model rockets, and they had some in their shop that were probably 10-12 feet long. I just had to imagine after 9/11 that there would be some scrutiny of anyone going down the road with one of them in the back of their pick-up truck

Large scale R/C aircraft is so cool.
There is a club in the western suburbs of Chicago that specializes in 1/4, 1/5 and 1/6 size planes. There is a guy who brings a B-36 with a 16 foot wingspan, and six weedwacker motors. My own 1/4 scale F-4U Corsair has been there, but many years ago. I went last year because it has been tugging at my coattails to get
involved again.
Here's some of the other entries;

Nope. Not until you tell us what you know about that engine in your last picture!

Either the guy flying the 747 is a much better pilot than the guy flying the B-17 or the B-17 is a very unstable aircraft. I noticed the inboard right engine quit during the flight on the B-17 and then the outboard right engine quit on landing. If he lost both in the air he would probably lose the airplane unless he could throttle the two left engines back and make it back to the landing strip in a glide.

The Liberty engine is scratch built, and powers the plane. The plane is 1/3rd scale, and I believe it is a Jenny. I
didn't think to ask about the plane, I was too interested in the motor. The 1/4 scale Goose is powered by two
oriental nine cylinder radials.
This Stinson has a seven cylinder Robart motor powering it.
Other interesting planes I didn't take pictures of were a PT-22 with a Yamada five cylinder radial.
A Piper Cub with a Yamada flat four.
A Sopwith Camel with a seven cylinder radial, the origin of which I do not know.
A Marchetti jet with a real turbo-jet motor.
An F-18 Hornet with two turbo-jet motors.
