I got a Saito 72 for my b-day. Haven't run it yet, but I expect it to swing a 14-6 prop.
What would be the target wing area for this beast? I believe in thick, blunt airfoils, moderate wing loadings, and flying 5.1 sec laps on full length lines. Traditional flapped layout.
I'm thinking around 740 squares.
Opinions?
Mike,
This is the plane I'm currently flying with, which I designed specifically for the Saito 72. Here are the specs:
Engine: Saito .72
Model weight: 65 oz.
Wing area: 685 square inches.
Line lenght: 68.6 feet (center to center)
Prop: Top Flite Power Point 14"x6" (stock) or Rev-Up 14"x6".
Glow plug: OS type "F"
Carb: Saito modified CL carburetor as per Bob Reeve's instructions.
Fuel: 10% nitro - 20% oil (70% synthetic-30% castor)
Fuel tank: 6 oz. plastic non uniflow. (with no muffler pressure).
Fuel consumption: 3.5 oz for a 6' 30" flight.
Ground rpm's: 8.4/8.5 K with the Top Flite prop and 8.8K with the Rev-Up prop.
Lap time: 5.1/5.2
The plane flies just GREAT and the engine not only gives me the kind of power I need to fly in pretty high wind conditions, but also
rock solid consistent runs in every single flight, even in hot humid days.
It works for me.
Claudio.
