big stik 60 on floats?
Here are the specs from the GP website:
Big Stik 60 ARF
Stock Number: GPMA1221
Wingspan: 73.5 in (1865mm)
Wing Area: 943 sq in (60.8 dm2)
Weight: 7.5-8 lb (3.4-3.6 kg)
Wing Loading: 18.3-19.5 oz/sq ft (56-60 g/dm2)
Fuselage Length: 54 in (1370mm)
Engine Required: 2-stroke .60-.91 cu in (10-15cc) or 4-stroke .70-.91 cu in (11.5-15cc)
Radio Required: 4-5 channel w/5 standard servos
With a 54" fuselage, add 4" for the motor and you get 58"
Use 75-80% of that for float length and you get 43.5-46.4, or 45" nominal floats.
Add another set of the same landing gear GP uses for the mains.
They probably have mounting blocks for both taildragger and nosedragger. If not, glue in another mounting block where you need it.
Put the step of the floats under the balance point of the airplane.
The floats should be parallel, with no toe-in. Angle the nose of the floats down a little. With the floats level, the wing should be at approx 3 degrees positive incidence. Both floats should have the same incidence.
Balance the airplane with the floats installed. If the plane was balanced with wheels, then rebalancing with floats is done by adding weight to the floats where needed. This way, it will still be balanced when you remove the floats and reinstall the wheels.
A water rudder helps crosswind taxi, but is not MANDATORY. Prop blast over the air rudder will turn the airplane as long as the motor is running. If the motor is not running, it doesn't matter.
