RE: Servos for Seagull Decathlon?
It's a great looking plane and about 90% complete out of the box.
I replaced the tailwheel with a sillivan unit.
The 425BB should be pushing about 60oz at 6V.
Keep in mind that I'm using the .75 because I'm flying in Pueblo at about 4200' elevation. I expect brisk performance--but it's not gonna be a hover monster at 8 pounds. Not even close.
The TH .75 is good for about 6.5 pounds if you want a hover monster that will rocket out and accelerate going up. This 8 pound airframe should fly very nice with my usuall Pro Zinger 13-5 prop and Omega 5% fuel. I may try a 13-6. I've run 25% through this engine before--and you can DEFINETLY see the difference in performance. But--I don't want to cook the engine or wear it out prematurely--so 5% is cheap and works well. Very dependable and reliable setup with 5% and some castor.
Decathlons aren't meant to hover anyway. It should fly with plenty of authority, and pull nice big loops, but I'm not expecting a Decathlon that will torque roll.[:-]
I do plan to fly it hard--so I'm going to put the 475BB on all the surfaces.
