About this Plan

Beechcraft H18 (Beech 18). Radio control sport-scale model twin. Wingspan 2400 mm.

Direct submission to Outerzone.

Quote (google-translated): "Beech H18: The Beech was first flown on January 15, 1934, and remained in continuous production until the end of 1969, which is certainly a record in terms of longevity for any aircraft type; over 9,000 units were built. The last 3 aircraft left Wichita for Japan Airlines on November 26, 1969.

Various advanced versions of Beechcraft's shuttle aircraft were used by the Allied Air Forces during the war for a variety of tasks. Transport and multi-role versions were produced in large numbers for the USAF under the designation UC-45, and the US Navy, pattern designation JRB, the RAF and Royal Navy (Expediter I and II), and some JRB machines had a dome-like version for observation purposes - enlargement of the passenger cabin.

Particular further developments were the AT-7 Navigator (navigation training aircraft), of which 1,112 were built, and the AT-11 Kansas (1,582 units built), a training aircraft for bomber and gunner training; Both types were used by the US Navy under the designation SNB. Some AT-7As could be converted to floats and snow runners. Today, many Beech 18s are still in use to drop parachutists.

The model: Not only the appeal of a two-engine aircraft, but also the special shape of this type were decisive in me deciding on the elaborate design of the Beech 18. Complex because the machine has a two-leg retractable landing gear and double tail. So I started planning about 3 years ago. The scale was chosen to be 1:6, which in my opinion is a lower limit for this type with the proportions and execution being completely true to the original.

My Beech was made entirely of wood. Only the cabin glazing and the landing gear shaft covers are made of plastic or aluminum. This usual, lightweight balsa construction method, which I always use, has a positive effect in several factors, such as overall weight, flight characteristics, strength, etc. For many model builders, the significantly higher construction effort is of course a downer, but for me only this construction method is real model building. It always fascinates me to complete the delicate basic structure of a wing or fuselage into a compact, stable unit.

In order to do justice to the model in as many details as possible, I of course also equipped my Beech with a self-designed telescopic retractable landing gear. Only the pneumatics with which the landing gear is retracted were not made by me. At this point, however, it must be mentioned that only the outer visible part of the chassis is completely true to the original.

The support and retraction mechanism was adapted to the spatial conditions and the space required by the wing. When the landing gear is retracted, it is covered by two covers, so that only half of it..."

Update 11/5/2024: Replaced this plan with a clearer copy, thanks to Pilgrim. This includes some previously missing sheets that show all fuselage formers, also full nacelle and retract drawings. Fullsize at 300 dpi.

    ScaleType: This (oz15284) is a scale plan. Where possible we link scale plans to Wikipedia, using a text string called ScaleType.

    If we got this right, you now have a couple of direct links (above) to 1. see the Wikipedia page, and 2. search Oz for more plans of this type. If we didn't, then see below.


    Notes:
    ScaleType is formed from the last part of the Wikipedia page address, which here is https://en.wikipedia.org/wiki/Beechcraft_Model_18
    Wikipedia page addresses may well change over time.
    For more obscure types, there currently will be no Wiki page found. We tag these cases as ScaleType = NotFound. These will change over time.

That's actually a D18, not an H. Looks to be a very nice plan though..

Um. You could take that up with Mr Fallwimmer, the designer. But here at Outerzone we just report the historical facts of which model plans appeared when, and the titles when printed.

When I see this plane, scenes from the movie Mad Mad World come to mind, with Buddy Hackett and Mickey Rooney in the cockpit. The Beech in that movie was a model D18. Jim Backus (millionaire on Gilligan's Island) was also in the plane as the pilot who was drunk and got knocked-out unconscious.

In this link is a history of the USAAF β€œAT-11” Twin Beech featured in Mad Mad World (it was a Model 18, but not a β€œD”), and the story of a Hollywood aviation filming business, Tallmantz Aviation: https://www.aerovintage.com/tallmantz-aviation/mad-mad-world-twin-beech/

Notes

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.

Scaling

This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
