My Sweetheart and I took a mini vacation to my hometown and brought some RC planes to fly at the field...

The Colt 35 , Fast Eddie , Top Flite Schoolboy all electric and the 84" Chet Lanzo RC-1 with original 1938 Brown Junior .60 on spark ignition.

Fuel used in the Brown Junior is Coleman lantern ( white gas or close ) & 30% #30 non-detergent mineral oil.... One flip starts were the

rule...

Sorry, i was not able to get any video this weekend though....

The weather was decent ( not too hot, low wind ) Monday Sept 6, and gorgeous ( no wind, not too hot ) Sept 7th.

Best regards,

jeff

After a crankshaft pulley repair and reassembling the sheet metal, a running video was taken. This tractor has a magneto ignition without an electric starter. An " Armstrong " starter is used - a starting crank to turn it over carefully to start....

I built H.A. Thomas's FM RANGER back in 2016. I enlarged it from the 24" span rubber powered model to a 32" span park 250 electric rc model. It flew O.K. but did not respond well on " rudder" steering. The dihedral just did not seem to be enough. I learned to fly it with that limitation but it just wasn't fun, and other projects led to it gathering dust. This spring, tiring of the pretty design setting on the shelf, i decided to take action. The wing covering was removed, the wing placed on the scroll saw and panels were cut carefully from the center section. The TLAR dihedral increase took place. The wing was recovered in blue litespan and a test flight showed it to fly like a totally different airplane - it is now very responsive and fun to fly. Sorry, but no video has been possible but when i can take one, it will be added to this post. The FM RANGER is a pretty design published in the June 1950 Flying Models , designed by H.A. Thomas. If anyone builds it, make sure to have enough dihedral ( or ailerons) and enjoy a very streamlined nice flying bird.

i'm now considering building the 24" original size for electric rc.....

Bruce Mathews is running the Vintage Open Kit build..... VOK. My entry was the Thermal Dart enlarged 125% with electric RC. The 1.9 ounce flying weight 30 inch wingspan model runs a single lipo cell and is covered with Easybilt tissue..... use the link to watch a cell phone video, using my face on throttle

Lightweight RC plane - 125% Thermal Dart (1 min 27 sec)


To see the build log with all details use this link : https://www.rcgroups.com/forums/show...tric-Now-Flown

It is a simple model but is giving me lots of fun, each flight is so slow .... The 300 MaH lipo gives 10-20 minutes flying time..... It is a calm weather flyer for early morning or evening.... an Indoor venue would be wonderful...

Build something yourselves and have fun,

jeff

In 1995 i finally was able to buy a new G-Mark .30 Twin from a local owner. Many years before that, i bought the Model Airplane News magazine the G-Mark .30 Twin review article was scanned from..... I have not ran this twin, it was new in the box. It seems to be a jewel.

Adrian's model engine site and other websites have a very complete G-Mark company history.....

Yesterday i purchased this built from original Topflite kit Schoolboy. It is finished in dope. The Cox .010 appears new. The model evidently was built to hang up and enjoy, there has never been RC equipment in it..... I will fly this model, after setting up for electric. The unknown builder was a craftsman, putting my builds to shame.....

Stay tuned,

Rather than repeat everything, here is the " Build Log " link to the Complete A Project 2020 ran by Sundancer :

My Megow Super Zomby electric RC conversion was built from Model Builder plans and the original and retouched plan and article on Outerzone. RChoper Gene did a wonderful digital rebuild of the plan and article as well.The Plan Page original article was nice to reference as well.... The ready to fly model weighs in at 18 ounces and is a real floater... First flights were this spring....

Polyspan and minwax clear along with some WBPU red for trim was used for finishing.

For anyone interested, please touch the link to go to my RCcgroups build log for the complete story, including a nice landing in a treetop.... Don't worry, the plane somehow worked it's way down with minor damage the next day. Phew.....

1947 Maytag 72 twin cyclinder running (0 min 30 sec)



The link is to the running 1947 Maytag twin cylinder engine . Maytag was from Newton Iowa USA. The twin cylinder engine superceded the single cylinder engines and was the last engine Maytag produced. 1937-1952. My engine was sold to a lawn mower company with conversion parts from Leclaire Mfg co. I bought this engine in 1987, and restored it ~ 20 years ago.

Best regards,

Maytag 92 gas engine running (0 min 43 sec)




All - the maytag was obtained 30 yrs ago, unsticking the piston , new rings , cleaning the carb resulted in a running engine. Then it went on the shelf for 19 years. Now it is still ugly but runs well again. Some new parts are on the way to replace whats missing, including a muffler.

Best regards,

Jeff

From the Master Bill Winter and scanned from my original issue of Model Airplane News May 1935 it's the rubber powered Vultee Transport.

This model looks well drawn and the plans are full size. It also looks like it would be a good flyer if kept light.

Enjoy,

Inspired to get another GHQ running, this time on spark ignition, I managed to my surprise found that this old " Q" fired off and ran steadily... A large " Ritz" prop was used , 50 % # 30 motor oil with 50% alcohol free pump gas is the fuel. The oil amount is to help seal the poor fits enough to run, it did not hurt. The engine leaked slightly from nearly every joint when running but the needle valve worked well enough to compensate for the leakage. Sometime, the engine will be taken down and the surfaces lightly lapped to improve those flange fits.

Many of these engines would not run when new because the instructions & illustrations from GHQ showed the ignition timer in a clock wise position. The late Bill Mohrbacher ( GWillie) youtube video helped save me a lot of time with his excellent information. For standard counter clockwise running, have the timer as shown in his or my videos. How many engines would not run " back then " due to this miss-understanding ????

It was satisfying to hear this classic actually run, the engine was notorious for poor quality....

Enjoy,

The 1946 Detroit Michigan USA made Delong " 30 " spark ignition engine was a well made unit which was setting control line speed and free flight records nationwide. Dick Korda flew his Powerhouse 56 with the Delong......

However, not all was perfect with these engines as John Pond recollected in the scanned article attached..... A scan of a photocopy of an original instruction and parts list is included as well.

I am preparing my Delong 30 for some test runs on spark ignition with gasoline ( lantern fuel this time ) and will add to this entry with pics and video then.

Enjoy,

I set up a portable ignition pack using a Modelectric coil, Tobe condensor and a 3.7v single cell LIPO battery.... The Brown Junior was purchased several years ago and was said to have been rebuilt. What better way to find out than with a test run or two ? Yes, the engine was exactly as claimed and was carefully adjusted to avoid overheating or lean running.

Regular unleaded pump gas and #30 motor oil was mixed to ~ 30 % oil ratio.... An old Top Flite Super M 13-6 was mounted. Needle set to three turns out and a couple choked flicks and the Brown started right up. They are a well made and easy to run engine, and a real classic. Sorry the videos are not to a high standard but i will improve on that That was the first time i have actually used gasoline in these antique engines - ~ 5% nitro 20% castor glow fuel was used to fly my RC1.

A long time friend had this Skychief and was obtained from him. The engine was in good shape except the crankshaft threads were destroyed and many original parts were missing. A parts Skychief was obtained from an RC groups fellow member and that engine provided the original needle valve / fuel tank assembly , crankshaft , spark ignition timer. The refurbished Skychief pleases me. The crankcase is very light zinc or such pot metal ??? the cylinder is very heavy cast iron. The piston has one ring of about 1/8" width. The piston was soaked for a week in ATF to help loosen the stuck piston ring on my Skychief.

Scanned from my issue of the June 1940 Model Airplane News is the Burd KORDA WORLD RECORD HOLDER.... That is a lot of model for 29 cents ...... This model is not the 1939 Wakefield, but an earlier model which won Mulvihill. I built one for electric RC years ago, it is a fine flier.

Also scanned from my issue of December 1939 Model Airplane News is the Country Club Aero Supply Jimmy Allen Sky Raider model kit.
