Telemaster 40 (oz9384)
About this Plan
Telemaster 40. Radio control sport model for .29 to .40 power. Wingspan 73in, wing area 848 sq in. Discontinued kit plan from Hobby Lobby.
The original Telemaster (oz5043) design was from Alexander Engel in 1968. This here is a later later kit (circa 1980) for 40 power. Later versions used strip ailerons. This one also shows flaps and tricycle gear layout.

User commentsI built my Telemaster 40 from the Hobby Lobby kit, which was cut by Great Planes. As such, the wood quality was excellent, and parts fits equally so. I modified my example with bolt-on wings, and incorporated the flaps and tricycle landing gear in my build. Power was originally an OS Max H 40, which flew the model very well. The model will fly inverted, but is certainly not happy doing so, requiring almost full down-elevator deflection to hold inverted flight. Best to roll out of inverted to level flight, as the 40 engine does not have quite enough power to execute a half-loop to right-side-up unless you have plenty of altitude. I later installed a Super Tigre 60, which certainly hauls the model into the air quickly, but the Telemaster does not fly any better than with the 40, and in my opinion, exhibits undesirable flight characteristics, so I have pulled the 60 in favour of a modern-day 46 2-stroke. My model is presently mounted on snow skis, but I have not had the chance to fly off snow as yet. The flaps add a lot to the slow flight characteristics, and are lots of fun to play with. The model will virtually hover into a modest head-wind with full flaps deployed, and has truly awesome slow-flight abilities using flaps. The OS 40 would be a perfect power choice for this model, even if the ready-to-fly weight is at the maximum specified. An excellent trainer, and large enough to be easily visible in the air. Full power is required only for takeoff and clowning around; the model easily maintains level flight at less than 1/2 throttle. About 1/4 flap on takeoff makes for a very nice scale-like flight path. You can use full flaps on landing, but keep on just a bit of power at touchdown to smooth out the landing. Tricycle gear makes ground handling nice and easy. I usually fly off grass, but ground handling off tarmac is equally good, except it takes much longer to slow down! I am including some pictures of my two Telemasters - the other is a Senior Telemaster [more pics 003-005]. The "40" is covered in MonoKote, while the Senior is covered in film acquired from HobbyKing.

* 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.
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.
