Kinda looks like a Liberator, doesn't it? That middle one just doesn't want to start..

Hi Isky

At the Teterboro Aviation Hall of Fame and Museum there are several pictures and some documentation of a FIVE engined B-17!
The plane was a test mule that had a 42 cylinder radial mounted in the nose!
One of these incredible powerplants is on display as well....


See Ya

It wasn't one of these, was it?

Yes, and a power on landing. But how do you score it? You are supposed to get one lap of even descent from the point where the engine quits to the point of landing. Which engine? All of them?

I think this is another good demonstration of the value of going electric.

Flip the switch. Take off. And they all quit at once.

Yeah, if you wanted a sensible airplane. I don't think that was the point of this, though, quite the opposite.

I was JUST waiting for him to pull up into a wingover. Ah well..

That starting proceedure looks like a perfect example of doing the same thing over and over again and expecting a different result!
I'm betting that less than four of those engines were running after one lap.

Now I know why I stick with singles. That 5 engine job is just self inflicted torture. Sure was entertaining though. I'm still laughing....

The 1/2A Multi-Engine Profile Scale event held here in Tucson each year and started by none other than Mike Keville (yeah that guy again) has become very popular and always chisels in stone how hard it is to keep more than one of these things running at a time, not to mention getting them started.
I've seen some very experienced modelers repeatedly fail at do so!
Physical torture in it's purest form.
Sure is fun to watch though.
Always some really nice airplanes.

Anyone try a Dornier Do-X yet?



Huh.. I never noticed before - the tractor engines have 4 bladed props, the pushers two bladed.

Hey Rich! Are you sure there wasn't a turboprop motor also in the nose of that B-17??? There are pics of BOTH versions.
------------
12/22/2006. Remarks by Gary Hebbard: "This aircraft carries the USAAF s/n 42-97849, the code DI-O, the name "Liberty Belle" and the nose art of the original aircraft of the 390th Bomb Squadron (Eighth Air Force) in WW II. The father of Elton D. "Don" Brooks, Jr., of Douglas, Georgia, USA, (founder and President of the Liberty Foundation) was a tail gunner on 30 missions in the original "Liberty Belle", while based at Framlingham, England in WW II.

It is pictured while on a tour of Newfoundland and Labrador (Canada) that was a major staging base for Europe-bound aircraft during the war years.

N390TH was built by Vega as Model 17 B-17G-105-VE and was delivered to the USAAF, s/n 44-85734, in 1944. On June 25, 1947 it was sold for scrap to Esperado Mining Co., Altus, Oklahoma, USA. Pratt & Whitney Engines of Hartford, Connecticut, USA bought the aircraft on November 19, 1947, registered as NX5111N (later N5111N), and in 1948 Boeing converted it to an engine test bed

The cockpit was moved aft several feet and the nose construction was strengthened to carry large radial AND turboprop (T34 & T64) engines. Fitted with a dummy nose the aircraft was transferred to Pratt & Whitney at Hartford, Connecticut, where the XT-34 turboprop engine was the first to be installed. The aircraft flew often on the tested engines only.

On June 16, 1967 it was sold to Bradley Air Museum, Windsor Locks, Connecticut, but was badly damaged by a tornado on March 10, 1979. Still damaged it was stored at the New England Air Museum at Bradley International Airport between 1981 and 1992. Tom Reilly of Vintage Aircraft, Kissimmee, Florida, USA, who became owner of the aircraft in 1987, started to rebuild it into a B-17G in 1992, using some parts of other B-17’s, including B-17G-105-VE, USAAF s/n 44-85813, which is now under restoration to flying condition also.

While under restoration ownership of the aircraft passed to Randsburg Corp, Portland, Oregon on July 13, 1999 and the aircraft was registered as N817BR. On September 10, 2003, the Liberty Foundation Inc. of Kissimmee reserved the registration N390TH. After a 12-year restoration, N390TH flew again on December 8, 2004."

UUhhhhhh, well...I doubt you could talk the Cholla Choppers and the parks dept into flooding the circle for one of those!
Maybe it could be flown from a boat on the model boat lake.

This would be a big project even as an electric.

I've seen flying boats at RC Scale at the Nats. They use transparent plexiglass wheels.

I wonder if there's a scale subject with a greater number of engines. Even the B-36D only had ten..

Here's where they controlled the throttles for the 12 engines:

Interesting video.

Id like to see someone else just equal what Paul did. Actually fly a competitive pattern with a 4 ( or more if you wish ) multi engine bomber.

Where's the KA-BOOM? There was supposed to be an earth shattering KA-BOOM!

Been done as a rubber powered freeflight.

Back in the 1960's one of the Adamissons built a plane with 9 Cox .049 engines. All hand started. Now THAT had to be an experience.

Gee.. check this out. EIGHT engines. No electric starters, even. Note the Coke bottles.
