About this Plan

Senior Telemaster. Radio control sport model. Wingspan 2400mm.

This is the original German version of the Senior Telemaster design from Alexander Engel KG circa 1970, complete with barn-door ailerons. For the later version, see RCM Senior Telemaster (oz5044) from 1975 using different construction methods including strip ailerons.

Later kitted by Hobby Lobby.

Quote: "Senior Telemaster has been developed especially for the fans of big model airplanes, and due to its high inherent stability and docile flight characteristics it facilitates proceeding directly from free-flight sport models to multi R/C flying. All controls and the throttle are provided for actuation. If for some reason the ailerons are not used, the dihedral should be increased from 65 to 130 mm (2-9/16 to 5-1/8 inches) to provide sufficient lateral stability.

Due to its high-lift wing airfoil, the Senior Telemaster is very well suited for special tasks like banner tow, leaflet and parachute dropping, aerial photography, etc., but it is suited for rather simple aerobatic patterns.

Building the Fuselage: Cut sheet 1 of the plan along the dashed line and glue the parts together so you have the complete fuselage views in one piece.

Now drill through the engine bearer bars 9 and glue a M3 (metric thread, about 1/8” diameter) nut under each drilled hole using epoxy. Drill the holes in the formers 12, 14, and 20, which are lead-throughs for the fuel tube, the throttle Bowden cable, and the tail wheel mount, and in former 14 make the cut-out for the tank.

Now assemble formers 15 to 20 and bind and glue the tail wheel mount to the back of former 20.

Assemble both fuselage sides from parts 1 to 6, and bevel the endings according to the top view drawing. Now drill the holes for the mounting dowels. Tack the right fuselage side flat upon the building board and glue on parts 7 to 15. Add parts 7, 9, 11, and 13 of the left fuselage side, insert the tank compartment cap 21 and glue on the left fuselage side.

Subsequently, raise the end of the right fuselage side by 52 mm (2.05”) and in this position, glue the ends of both fuselage halves together. Insert formers 16 to 20 and glue on the nine fuselage bottom pieces 22 and the landing gear rest 23.

When the glue has well settled, the fuselage may be taken off the building board. After this, the upper cap bars 24, the former bracings 25, and the lower cap bars 26 are glued in. Now the landing gear parts 28, 29, and 30 are bound together using binding wire, and glued with epoxy or soldered. Install the main wheels 31 on the main landing gear. Now glue the tail wheel strut 32 into the tail wheel mount and install the tail wheel 33.

Following this, cut (saw) the engine bearer plate 34 appropriate to your engine and drill eight holes, of which the four inner ones have to fit the engine and the four outer ones have to fit the engine bearer bars 9.

Now the fuselage is carefully trimmed (fettled) and all edges, except the wing and tail saddles and the landing gear rest, are well rounded..."

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.
