Another warm Winter evening in Minnesota!

We had 28 members and guests join us for presentations, discussions and plain old story telling.

Cal Branton sent his regrets that he could not join us due to his previous commitment to the ski slopes of Colorado...

Dennis Simmons CARF Spitfire Project

Last December Dennis had brought in his 3 cylinder in-line Kolm IL150 4-stroke engine (previously mis-reported as a ROTOmotor 130cc) for use in his CARF-Models Supermarine Spitfire Mk. IX.

Dennis is looking for support from previous builders on how to mount the Kolm in the fuselage.  The fuselage is a beautiful composite structure with no internal bulkheads.  The original kit is set up for a DA-85 with a canister muffler.  The use of the multi-cylinder in-line requires that the firewall be removed and relocated further back to near the wing.

CARF-Models 1:4.2 Scale Spitfire Specifications:

  • Wingspan:                 102” (2.58m)

  • Fuselage length:       88” (2.24m)

  • Power:                       Using a Kolm IL150-LE

  • Estimated Weight:    38lbs (17 kg)

He's thinking of assembling the engine and mounting system to an unattached firewall to determine the mounting location.  The best news is that he most likely will not have to add weight to the nose to get the Spitfire to balance.

Dennis is looking to modify the Spitfire’s outline to make it more of a Battle of Britain version.

We look forward to seeing it fly this spring!


Karl Hansen’s Lockheed P2V-7 Neptune Subchaser

Wow! TWO Lockheed projects at the same meeting!

Karl has a new project.  He designed and is building a 2-engine submarine chaser!  The construction is his typical interlocking laser cut design allowing for modules to be simply assembled.

According to Wikipedia: “The Lockheed P-2 Neptune (designated P2V by the United States Navy prior to September 1962) is a maritime patrol, anti-submarine warfare (ASW) aircraft.

It was developed for the US Navy by Lockheed to replace the Lockheed PV-1 Ventura and PV-2 Harpoon and was replaced in turn by the Lockheed P-3 Orion.  Designed as a land-based aircraft, the Neptune never made a carrier landing, but a small number were converted and deployed as carrier-launched (using JATO assist), stop-gap nuclear bombers that would have to land on shore or ditch.  The type was successful in export, and saw service with several armed forces.”

Lockheed P-3 Orion 1/12th Scale Specifications

  • Wingspan:            104” (2.64m)
  • Fuselage length:   89” (2.26m)
  • Power:                  considering (2) 20 cc gas

Karl plans to take his aircraft to the Warbird & Classics Events this summer!  He may choose to kit the P2V-7 if there is enough interest.

We look forward to seeing it fly this summer!


Scott Anderson’s CMP F4U-1A Corsair

Scott showed his auction find from the TCRC 2024 Auction.  The model is a China Model Products (CMP) F4U-1A Corsair.  The model was built as fixed gear with Robart scale Oleo Struts.  It is electric powered with a RimFire 1.20 motor, 100A ESC-BEC and uses a 6s-4000 battery.

The model was painted with epoxy KlassKote paint over the composite airframe.

CMP Models F4U-1A Corsair 1/5th Scale Specifications:

  • Wingspan:               78” (1.98m)

  • Fuselage length:     68” (1.73m)

  • Power:                     RimFire 1.20 motor w/100A ESC

  • Estimated Weight:  planning 12lbs (5.5 kg)

Our next meeting will be Friday March 22, 2024.

Andersen Designs & Scale Flyers Highlighted

Once again we were honored to have David Andersen Designs and the Scale Flyers Website highlighted in the Scale Aircraft section of the 2024 March Model Aviation Magazine.

Considering we are just a bunch of nerds who enjoy building and flying Scale Aircraft, it's an wonderful to have thousands of visitors from all over the world who are interested in model aviation stop in each month to see what we're up to.

Although not always covered in our N ewsletters, we encourage all of you to pass on your acquired building knowledge and flying skills to individuals of all ages.  As important are safety basics and flying procedures to further ensure our hobby continues to flourish well into the future!

Model Aviation Magazine please except a BIG THANK YOU ... from all SFM Members.


Ron Jesberg’s Lockheed Model 9 Orion Project

According to Wikipedia: “The Lockheed Model 9 Orion is a single-engine passenger aircraft built in 1931 for commercial airlines.  It was faster than any American military aircraft of that time.  In fact an earlier designed single seat version beat Howard Hughes' H1 in the transatlantic races in 1929.  Designed by Richard A. von Hake, it was the last wood aircraft produced by the Lockheed Aircraft Corporation.”

Ron joined the Scale Flyers of Minnesota in January 2024 and at this meeting Ron brought his Lockheed Model 9 Orion Project that he researched, drew the plans and built the aircraft.  He’s put in years of work and is looking for someone to check it out and perform the maiden flight.  It is an impressive project and looks to be well built!

Lockheed Model 9 Orion 1/5th Scale Specifications:

  • Wingspan:                102” (2.58m)

  • Fuselage length:       68” (1.73m)

  • Power:                      Using a DLE-50 cc

  • Estimated Weight:   Approx 32# (14.5 kg)

As Ron tells us ...

“I first saw the Orion in a trade magazine in 1976 and knew right away that I wanted to model it.  Off and on, over many years I collected pictures and information on it.  In 2015 I discovered actual shop prints from the Lockheed factory in Burbank California, circa 1932.  That was the find that spurred me to undertake the project because up until then I had not been able to find any drawings I trusted.

Many years of kits and a few scratch builds made me confident I could do a large-scale model.  I am a manufacturing engineer for an aerospace company, so my CAD and technical skills enabled me to model this aircraft.  I sent the CAD files to a laser cutter.  The plane is all balsa and ply including the cowl.  I made molds for the windshield and windows. I created all the graphics in CAD and had them cut by a vinyl cutter.”

There was some discussion about baffling the engine to ensure adequate cooling as well as the possibility of adding dummy engine detail in the future.

We look forward to the maiden flight this spring!


Chris Launer’s Weapon Load for F35 Jet Fighter

Chris showed a set of weapons built-up for the F-35 Lightning Jet Fighter built for Mike Danielson.

They are intended to fit in the weapons bay that can be opened in flight for display or launch!

We all are looking forward to seeing it fly this spring!

To All of Our Worldwide Visitors ...

We appreciate your questions, inquires and support to keep Scale & Giant Scale R/C planes flying everywhere!

Share your knowledge ...
