Senior Telemaster

Hi All,

Just got a kit for a Senior Telemaster to replace the plane I rekitted, and didn't get any info from the Tech Guy at Hobby Lobby, so I figured I'd go to the experts. Anyway, this will be the biggest plane I've had, so a few questions. I want to do bolt on wings, but that seems easy. I also want to use separate servos for the ailerons.

Do I need ailerons the full width of the wing, or can I shorten up to 18-24 inches? Will a standard Futaba servo be strong enough for the job, rudder & elevator too? I have an 8 chan Futaba TX/RX so I would like to add flaps, separate from ailerons. Rather do this than combine flaps & ailerons in the 'puter. Gives me more knobs to diddle.

I'll be powering this plane with an OS61 2 stroke from the last plane, and am wondering if a 12 inch prop sounds right? Maybe a 12x5 or so??? Looks like a 12 inch will clear the ground easily. Thinking that 11x5=55 and 12x5=60, so pretty close for power. Any other ideas???

Once again, Thanks for all the ideas or comments.

Shorter will work OK.

The plane will be flyable.

It will fly differently with more powerful servos.

Is the difference in response worth the difference in price? I think so, but YMMV.

Yes, it's fun to play with the extra control surfaces.

I've got a Hangar 9 UltraStick with flaps that can also do crow (droop ailerons, raise flaps--maximum drag).

I enjoy fooling around with the different flight modes.

I think of 12x6 as the standard .60-size prop.

So I'd move to 13x5 if you want more pull and lower top speed.

Let us know how it turns out!

******But, increase the chord by x2. Nothing worse than a lightly loaded flat bottom wing flying in the wind without sufficient authority to control the model.
******I agree with Marty that more servo power is better. Don't forget about using two more of the same type of servos to "double-up" on the rudder/elevator.
******Your engine will easily handle a 12x6-7 to a 13x5-6 without sweating it.
******Like, Marty, I'm interested in reading about your experiences. Just like talking models at the field.
