Senior Telemaster (oz5044)
About this Plan
Senior Telemaster. Radio control trainer/sport model. Wingspan 95 in, wing area 1330 sq in, for .40 to .60 power and 4 channels.
Note the original Senior Telemaster (oz9275) first appeared in 1970. This is the design as published in RCM later.
Quote: "First produced as a kit in Germany, only a few were exported to the US before the kit was discontinued. Reviewed in the April 1973 issue, the Senior Telemaster has become one of the most popular and sought-after designs in the country. RCM was fortunate to secure the publication rights to Alexander Engel's mangificent 95in span aircraft. A few minor modifications have been made to improve the structural integrity of the model, although little could be done to improve the outstanding flying characteristics of this magnificent aircraft.
No doubt about it, you're about to be the proud pilot of one of the biggest model airplanes on the block! First you get yourself a balsa tree - or forest? It sure takes a lot of sticks. This isn't the ideal plane to build in an apartment closet. The plans alone are big enough to paper an average outhouse twice over. You'll find out for yourself as you unfold them!
While the new version of the Sr Telemaster looks like the original machine once kitted in Germany, the new one boasts some design changes. The changes were made both to simplify the construction and to offer a stronger airframe.
The barn door ailerons have been changed to strip ailerons, They're easier to build and set up and they offer a stronger wing trailing edge. Heavy spars, full length 1/2 x 3/16 in strips running along the front of the wing, a 1/4 in ply spar dihedral brace coupled with a 1/8 ply leading and trailing edge dihedral braces add up to a wing that's almost strong enough to make a diving board for the local swimming hole!
A dorsal fin has been added to the vertical fin for strength. The stabilizer has been re-designed to make it more twist resistant and the fuselage construction has been changed to make the building easier and the airframe stronger.
This new ship will fly just like the one Chuck Cunningham has mentioned a few times in his column in RCM: The airplane that I was flying yesterday and have been flying for the past several months is one that I have mentioned before. It is the fantastic Senior Telemaster, a German kit that is no longer in production. I sincerely hope that either the kit can be started up again in Germany or someone in this country can get the kit rights to it and produce it here. Well, Chuck, you can stop lending out your plans, here comes the 'fantastic Senior Telemaster,' one more time.
As far as the construction on the new version goes, we're sure you'll agree that it's simple. Not a lot of little pieces to be glued in place here and there. The plane takes a while to build though, because there are a lot of big pieces to be glued together. To make the construction notes easy to follow, the first time a part is used, the name of the piece is given in italics. The star (*) is used to indicate that we've said all we're going to say about installing a particular piece and it's time to get out the glue.
In this article we've included a list of the additional materials you'll need to get the plane built. When it comes to finishing the plane, any of the possible covering techniques may be used, including MonoKote. That's what we used to cover ours. Incidently, if you want to cover the plane with one color and don't mind a few patches, you can get by with 3 rolls of the stuff. For two colors it will take 4 rolls; 3 rolls for the wing and 1 roll for the fuselage! Gad, that's enough to cover 4 x half A's, 2 x .19 sized ships - ah well, just think about how beautiful it will be up there. With a little headwind, you'll be able to hold it still in the sky above you to shade you, your family, and your car!
We're flying our ship with a Veco .61 and an 11-1/2 x 7 prop. A friend of ours who also has been flying one for a year has an .80 on his. Sure takes-off fast. About 3 feet of roll on the runway and it's up. Our radio is one of the new Hobby Lobby 6 RC systems.
Now it's time to get started. Move out the living room furniture, roll back the rug, lay down your building board and plans, get out your balsa forest, bucket of glue, and here we go.
THE WINGS: To make the building go more quickly, both of the wing panels are shown on the plans so you can build them both at the same time. In looking at the plans you'll find that the root rib and ribs #2 and #3 are in two pieces. They have been designed this way because of the 1/4 in ply dihedral brace. When you glue these two piece ribs in place on the first wing panel use the 1/4 in ply dihedral brace as a spacer to set them up. When you glue the ribs onto the second wing panel you'll glue the dihedral braces in place while gluing in the ribs..."

I've flown several of these over the years and it's true, nothing flies like a Telemaster. The original German kit became unavailable when the Germans were unable to get the wide 48" balsa sheeting for the wing. Hobby Lobby (now Hobby Express) arranged to have the kit made in the USA instead, and this is the version in the RCM plan. They substituted thin strips for the leading edge sheet and just left the trailing edge out, using strip ailerons instead of barn doors. But it still flies like a Telemaster. It will take off (and land) crossways to the runway, and you need to do this in a stiff wind or it will get blown over in anything more than a gentle breeze. It will teach you how to use the rudder to co-ordinate your turns just like in a Cub, and you'll learn how to keep one wing down in a crosswind takeoff. Side slips are a lot of fun because the Telemaster is the perfect plane for one wheel landings. I flew one of the ARF versions covered with some kind of LizardKote, not the real thing, which wasn't stiff enough and the whole wing fluttered when I got it too fast, which it will do with any 60 engine. I suggest wing covering with MonoKote only, not the softer stuff for added stiffness. Go ahead and try one, you can't go wrong, electric is no problem either.DougSmith - 05/07/2015
Photo of my Senior Telemaster, which I built in 2017 [more pics 006]. Overpowered with an OS 70 Surpass.

This is my Senior Telemaster from RCM plans [more pics 007, 008]. It flies extremely well on an OS 91 FS.

Sr. Telemaster [more pics 009-012]. Rebuilt by me in the late '70s. Powered by a K&B .61 with a special muffler of my own design, it is a superb flyer. With the flaps extended it will fly very slowly. Running a 12" x 4' Top Flite prop the climb is spirited, to say the very least. I covered the model in red Super Monokote with the white cross of Switzerland on the tail winch allowed me to use HB-PDP as the license number. PDP stands for "Perry Directional Porting" which was a power enhancing modification for cross scavenged two stroke engines. I'm afraid that PDP is lost in history.

Hello, Outerzone. My first Senior Telemaster, a Hobby Lobby kit, was powered by a Fox Eagle IV 74. Unfortunately, it seemed like something was missing. It was not what you'd call a great flying machine. So I gave it away for free, engine and all. However, since I thought that something was inherently wrong with the build which caused my ho - hum response, several years late I decided that it was time to give the Senior Telemaster another try. Of course, that meant a few design changes to correct the "problems".
Major mods included boosting the power to an OS FSR 1.08 engine, incorporating a two piece clipped wing which was shortened by 2 bays per side to a span of about 82.5 inches, adding functional lift struts, replacing the landing rear with a stouter, taller, wider unit, using 1/4 scale Du-Bro inflatable Cub tires, stiffening the rear fuselage section and replacing the vertical tail and rudder with those of Cessna 180 shape.
The flaperons were totally unnecessary as the plane could fly backwards in a mild wind without them. Take off roll was almost zero. Flight was slow, as intended, but solid with unstoppable climb and pulling power due to the improved engine performance.
Even with the clipped wing, rolls, split-S, inverted flight and spins, whether on land or floats, were all done with great ease and confidence. Best of all, IMO the appearance was much improved by the simple cosmetic changes. A couple of pix here of the plane in the air, extracted from a video [pics 013-015].
Here is some online video of it on floats: https://www.youtube.com/watch?v=fy-p5IwZikc. The spin and high G force recovery prove the integrity of the wing mods.
Cheers,

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.
