Quote: "Graupner Amateur. RM TEST. Report and photos by JG ELSON.
WHEN the preliminary review of this kit appeared in the October 1966 issue of RADIO MODELLER. I thought it would be just the model in which to try out my new OS single channel outfit. A description of the kit's con-tents was given in the Trade News, so it will suffice here to say that I can endorse the statement that this is a quality kit - all the wood being of a good grade and, apparently, very carefully selected for its particular purposes.
The only 'chore' was that of fretting out the few 1/8 in ply parts from the two printed sheets, and this did not really take very long, even with the lowly handframe. These, and the 1/8 balsa ply (beautiful stuff, this!) die-cut formers, help to make a really sturdy job of the fuselage. The building of the basic fuselage is quite straightforward, being simplified even further by the very explicit instructions and detailed exploded view contained in the manual.
I wanted to use the RMK Dynamite and Dynamo, motorised actuators - a natural with the OS superhet as it is a relay receiver - and decided this would be easier if I modified the fuselage slightly. This entailed lowering the engine servo platform to bring it in line with the fuel tank former, as shown in the photograph. This illustration also shows the tank which I made up from sheet tin-plate. It is of the good old square-box variety and has proved quite satisfactory, giving about 12 min run with the OS Pet engine. By lowering the servo platform, a free, out-of-sight, linkage can be achieved, with everything in line. The engine was mounted on a paxolin plate, and slots were cut in the side cheeks at the correct downthrust angle, so that this could be slid in.
The fuselage took only two evenings to build, and no doubt would be even more rapid were one using Graupner gear, when no mods would be necessary. Building the fin and tailplane also took next to no time. The elevators and rudder are cut from a very hard piece of trailing edge stock, and were finished and set aside for fitting after the model was covered. The wing is always the most critical part of any model, and I took great care to ensure both panels were accurate..."

Dear, I build the amateur graupner, with the plan of the site outerzone. Thanks for the plan. Fly it with 1.76 cc, weight 705 gram. My site http://users.skynet.be/fa046192/ - Greets,Julien - 22/06/2013
Thanks so much for saving all these precious plans. The Amateur was my first RC plane, and it was so a good plane I could fly it alone @ third flight ! Engine was a Taifun Sprint 1.78cc and radio a Kraft KP4B series 70 w/ KPS12 servos. Surely I'll rebuild one soon...

Hi Mary/Steve, here are some inflight pics from my Amateur, it is a restoration from a 40 year old model [modelpic & more pics 005-007]. Have a nice Christmas,

Hello, here are my pictures for Amateur [pics 008-010]. I followed the blueprint in the form of the material and the finish, which I made with Oracover iron-on foil and Oracover Sick. I still had an original nose gear in the basement, including the wheels are an OS 10 with 1.5 ccm. with an 8x4 Graubner Nylon propeller. The first flight was in August 2019, the plane flies beautifully and I am happy to have built the little thing. Thank you for that Great site and the opportunity to look at blueprints from my youth. Sincerely,

Bonjour Mary, I am sending you two photos of L'Amateur (first version) by Graupner, which I built in 2022 [pics 012, 013]. I wish you a good day. Cordialement,

Hello to everyone, is there a chance to get the plan of the Amateur II as well? I only have the plan for the fuselage, but it is severly damaged and I have no possiblity to get it scanned. The wing itself is still working and flies very well. Cheers and Thanks a lot!

Hello Steve and Mary, Here I am sending you the pictures from the Graupner Amateur [pics 014-018]. However, I EXPANDED the plan to 200%. The wingspan is now 2.20 m and the length is 1.70 m. The engine is an OS Fs 91 4 T, the system is Mpx 3030.35 MHZ. The plane is built with balsa and poplar plywood on the surfaces one piece, with 10x10 BALSA bars, 3 balsa casing, 5 balsa ribs, HL and SL made of 10 balsa material exactly as shown on the plan. The hull made of 4-gauge balsa and poplar plywood. The landing gear is also according to plan. The whole plane is covered with the new Kavan foil, which is a really great material and is very easy to work with ,Area +1.5 HL 0 degrees. Kind regards,

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.
