RC B-47 built by Sergio Vergara.

We are surprised to find so few rc B-47 radio control airplanes. The rc B-47 looks good and appears to have the proportions to make a good rc airplane.

The rc B-47version with propellers and jets would make an interesting rc airplane. Imagine how a rc B-47 would sound with turbojets and engines turning propellers?

In the picture directly above is the rc B-47 slope soarer scratch built by Sergio Vergara. It has a wingspan of 52" and uses aileron and elevator controls. Construction is all EPP foam. All up weight is 40 oz. Sergio tells us that his rc B-47 will fly well in winds above 10 mph.

The 116 foot wingspan B-47, made by Boeing and called Stratojet, was a bomber with a maximum weight and an ordnance capacity greater than most WW II heavy bombers. It was the first swept wing bomber to be deployed by the U.S.A.F.

The B-47 had jet fighter speed and maneuverability. It needed six jet engines for sufficient power, and even that had to be supplemented with Rocket Assisted Take-Off (RATO) from 18 booster rockets for heavy pay loads.

The rc B-47 shown just above is a profile model built by jiBerk of RC Groups. It is pusher prop powered.

The first B-47 aircraft did not have in-air refueling capacity. This meant that they had to be deployed from basis within round trip range of the Soviet Union in order to act as a nuclear deterrent. Once in-flight refueling was adapted, missions as much as 36 hours long were flown to demonstrate the effectiveness of the aircraft.

Pictured above and below is the great looking rc B-47 built by Mike Potter. We want to thank Robert Hill for sending the pictures to us.

Although the B-47 was intended for high altitude missions, the development of surface to air missiles by the Soviet Union altered that mission. It required the strengthening of its air frame in order to perform missions below Soviet radar detection levels. Another version of the B-47 was a dedicated reconnaissance plane.

When maximum deployment of the B-47 was achieved, over 1,300 of the aircraft served with 28 Strategic Air Command wings.

A total of 2,039 B-47 aircraft of all types were produced.

Robert Stoneberg ([email protected]) writes about his rc B-47 project: "I have begun a rc B-47 project in that I have built some test models, glide, CG, etc. The final larger rc model still has to be drawn up. The idea is to build an electric powered RB version with all the humps, bumps, and other electronic appendages per the full size, with a scale of about 1"=2 ft. This works out to a W.S. of near 60" and a fuse. a bit less. I plan to use thick (2") foam, laminated, & strenthened with carbon fiber, in the fuse. The rc B-47 wings may have to be standard balsa constr. with a non- scale airfoil shape. perhaps a thin Clark -Y. My little rc B-47 gliders seem to like a 20 degree wingsweep rather than the scale 35 degrees. Slower landings. Probably skidded in on its belly/ALD-4 pod config. might be best. The scale LG may prove to be too much, which I think is why few have built this bird as a model. The full scale B-47 was a real "beast" to set down smoothly until the pilot skill level improved. I know, for sure about that! Powering the rc B-47 --- I think I'd like to use a quality E. brushless. Maybe AXI from Hobby-Lobby. Now here is the biggest diff: The rc B-47 motor would be set into the nose with a folding prop and a scaled nose spinner. The 6 rc B-47 jet engines would all be scaled dummies, and made to come off easily w/o tearing the wing off. I'd need a bit of non-scale dihedral to help keep the ground clearance, also. RTF weight I estimate of the rc B-47 is near 5 lbs. As you can see, this rc B-47 is not for sissies, but a fun challenge. I would love to get some input on this rc project. You all probably have lots of "whys, how comes, etc, etc's , so have at it, please!"

Experimental B-47 version D

The XB-47D verstion of the B-47 was the world's fastest combined jet and propeller powered aircraft with a top speed of 598 mph.

On Aug. 26, 1955 the first of two modified aircraft took to the skies to test the theory that an aircraft could have the acceleration of a propeller driven plane with the top speed of a jet. The aircraft had their inboard jet engines replaced with 9,710 hp turboprops driving huge 15' diameter, 2' wide propellers.

Tests found excellent performance and few problems. However, more modern jet engines were able to have quicker acceleration, and a combined jet and turboprop powered B-47 for the USAF was never developed for deployment.

We received the following email from Ed Clayman - FliteMetal.com:  "I appreciate your mention of our two (2) rc B-47 aircraft featured on Wattflyer.com. My rc B-47 design has a 137.5" wingspan. The initial scale of these projects was just over 11.00% resulting in just over 121" but grew to 137.5" @ 10.2% of the full size B-47E IV when initial workup was finished. I am the designer/builder and Sam Collins is my partner in this crime. My rc B-47 is the most aggressive version of the B-47. This being a replica of one which practice bombed my hometown in the mid 1950's. I arrived home from school, grabbed a peanut butter sandwich then about 4:00 pm sat on my front doorstep waiting for an afternoon bombing run of my hometown by the USAF as it practiced low altitude attacks of the then Eastman Kodak Holston Ordenance Complex's Area A and B, as I sat watching from my ring side seat, so to speak.)

The B-47 performed a LABS (low altitude bombing system) maneuver. My hometown (Kingsport, TN) is located at the southern most end of the Shenandoah Valley. The USAF practice bombed industrial complexes along length of the 500 plus mile long valley floor. Missions began nearly a thousand miles away, off the coast of Maine. Sam's rc B-47 "weather bomber" replica of the B-47 was utilized to gather nuclear bomb fallout samples from Russian's nuclear bomb testing in the Siberian test ranges just beneath the Artic Circle, above China. This location was to more or less permit fallout to drift East over Arctic Sea instead over China. The remoteness afforded the USAF an ability to get in between mountain ranges above and East of the test sites with minimum exposure to Russian air defenses.

That's the long and the short of our 10.2% rc B-47projects. Thanks again for including our project in your rc B-47 overview."

The AMA has plans for a control line model. It should be fairly easily converted into a rc B-47. It has a 46" wingspan.

Model Aviation News also has plans for the aircraft that can easily be converted in to rc B-47. It has a 54" wingspan and a length of 43".

Dave Gee of RC Universe is looking for drawings to help him build a rc B-47.

Joe Martin of the New England Radio Control Modelers built a rc B-47. It is propeller driven and has a wingspan of 6' 8".

Capt. Midnight at WattFlyer started a construction thread about his rc B-47 with a 87" wingspan and a 80" length. Power comes from HETRC 6904 EDF units.

GGRW at WattFlyerRC is building a rc B-47 with a 90 1/2" wingspan that is 79" long and weighs around 2 1/4 lbs. It will be driven by Feigao motors and GWS fans.

Steve C68 at RC Groups posted about rc B-47 drawings.

Paul Willenborg posted to RC Groups about wanting to build a rc B-47.
