Thanks, I don't want to screw up this one. It is very nice plane and it should fly well.

If it happens that I will have to use Saito, I will add Perry pump to keep it running always the same way. I hope it is a good idea. Also a header tank may add some reliability.

As for the surfaces.

Rudder (not counterbalanced part) - 30cm long, 15 cm chord.
Elevator (one half) -33 cm long, 10 cm chord,
Aileron - 60 cm long, 7 cm chord.

I run this thorugh servo calculator taking max speed = 80 mph and max deflection = 45 degree.
Here are the numbers:
80 mph - Rudder = 260 oz-inch, Elevator = 127 oz-inch, Aileron = 147 oz-inch
70 mph - Rudder = 199 oz-inch, Elevator = 97 oz-inch, Aileron = 112 oz-inch
60 mph - Rudder = 146 oz-inch, Elevator = 71 oz-inch, Aileron = 82 oz-inch

It is insane[X(]. I can't put a 5oz giant servo for rudder. It is a small plane.

I will ignore rudder then and use the strongest digital I can have: HS-5945MG (181 oz at 0.13s).
Elevator is not as critical so I can live with cheaper HS-5625 (131 oz at 0.14 s).
As for the ailrons I can use HS-5645 (168 ox at 0.18s) or use Tower deal for HS-5625 (4 servos for $186.97 - it's over 30 bucks saving). Or maybe my LHS can match Tower deal but mixing 5625 with 5645 (both cost the same).

This makes 305 bucks for all servos including HS-225MG for throttle.[X(]
