Scanned from my original issue of the May 1940 Flying Aces it's the Bambino Bipe - an interesting rubber powered biplane....

It looks like it would be a good flyer....

Enjoy,

Having obtained a 1951 ? IMA FROG 150 Diesel I have scanned the original instruction sheets and the parts list. Also, the 150 Red Glow instructions are included. The glow version was a failure and only offered for a short time early in the production from the factory in England....

Hi All-

This Megow AYA #4 Junior Endurance was scanned from my original 1940 Megow plan. The file size reduction is mine on this one. No clean up of the scan was attempted but it is the real thing...

AYA is Air Youth Association which was an organization intended to promote model airplane building and air mindedness amongst young people in the USA.

Most model companies participated in the AYA programs using standard designs or in many cases, their own designs such as this one from Megow.

It looks like it would be a really nice flyer and doesn't look to really need changes to build and enjoy it....

Enjoy,

jeff

Hi Everyone-

Today i was able to take a short video of the 1950 Campus 29 glow engine running.... Campus Industries was an effort by Bill Brown , designer of the earlier famous Brown Junior .60. The intention of Campus production was to give college students an opportunity to earn , and learn their way through college by building and selling the Campus 29 and various CO2 motors.
This 29 engine used a Rogers case, shaft, needle valve assembly combined with a blind steel cylinder and a steel piston.The Campus 29 was intended for beginners to glow engines so it had only moderate power but was very small for it's displacement.
My Campus 29 needed longer cylinder attachment screws due to the supplied screw threads stripping out. Longer screws were obtained and nuts were added on top of the cylinder flange for a little insurance for retaining the cylinder.
The attached review was printed in the February 1951 Flying Models magazine.

Enjoy, it's a short video though......

Hi Everyone-

I built a Carl Goldberg Models 1/2 A Blazer from my original kit plan. My wing warped badly so I never did get to fly the kit model years ago.... This build soothed my errors from all those years ago and ended up with a really nice flying model.

best regards,

jeff

Hi Everyone-

Attached are scans of the Fokker D-8 by Harry Shaffer from my original issue of the January 1935 Universal Model Airplane News.

It was published full size as a rubber powered model. It looks to be a good flier and could easily be converted to an electric RC project.

Enjoy,

Hi Everyone -

Scanned directly from my issue of the November 1948 Model Airplane News it's Bill Winter's Swish...

It's an early Jetex rocket powered model for free flight and is rather large compared to later Jetex models.

I would say the Swish is a nearly forgotten model from the Master....

Enjoy,

This is my Gordon Englehart 1936 ARUP rc conversion. The original model was a 24" rubber powered craft, I extensively redesigned the wing ribs. It uses a hextronic 10 gram outrunner, AR6400 BL and two parkzone linear servos.Solite yellow and modelmaster red paint cover it. A 350 MAH LIPO fuels the 4.4 ounce ( 131 gram ) flying weight model.

The first video was made from my cell today during the second flight. The first flight flew out of my hand but after a few seconds went into a tight but slow flying turn. reducing throttle and neutralizing the stick allowed the model to straighten up and come down to a reasonable landing. An elevon end push rod wire had come unglued. At the same time it was noticed one linear servo had " dead " spots and would randomly just not function. A new servo was obtained and that was the cure....Got lucky with this slow, light model which went on to a 20 minute second flight, and many fine flights since.

Hi Everyone-

Scanned from my issue of the June 1947 Flying Models - the Thor engine review. Most Editors didn't bother reviewing these " slag " engines so this is probably one of the few reviews published when these engines were new.....

Rogers RMC2 test run on glow plug (0 min 22 sec)


The 1940s Rogers RMC2 all aluminum " slag " engine was a very popular engine of which most would run, but wore out quickly due to the all aluminum construction. The spark ignition timer prevented many from running at all until the glow plug was introduced. SIG 5% nitro 20% castor oil glow fuel and a Fox glow plug were used. The next test will attempt a run on spark ignition....

New Hope Super 29 test run (0 min 21 sec)


The New Hope Super .29 glow engine was made in early 1950s Japan. This rare engine was given a bench run yesterday using a vintage porcelain glow plug of unknown make. SIG 5% nitro 20% castor oil fuel and a 10 3 1\2 wood prop was used. It was a very friendly engine to operate and started easily....
