Hello Folks, I just maidened a Hangar 9 Tango yesterday. She flew great with an Evo .46. Plenty of power for hovering, knife edge loops, etc… The power off full rudder flat spins were gorgeous.

Anyway, I bought this plane in preparation for a Lake Powell Boating trip next month.

have always wanted to fly a float plane in Powell.
I purchased a set of floats from ebay: (Item # 320383842198). They seem about right:
24 ounces
33 inches long
17 inches from tip of float to step
4 inches high at step
3.75 inches wide at step
15-1/2 inches wide stance (center to center of floats) when assembled

With the Tango:
Wing Span: 48.5 in (123.19 cm) Overall Length: 49.5 in (125.73 cm) Wing Area: 747 sq in (48.19 sq dm) Flying Weight: 5.5 lb Engine Size: .46 2-stroke; 4 to 5 in back from leading edge at the wing root Wing Loading: 17.4 oz per sq ft Prop Size: 12x4

The Tango has about 7 inches of tail feathers on it so at 80% from prop to elevator hinge, 33 inches is perfect. She’ll end up a bit more or less then 7 pounds with floats so 3.75” is a touch wide but I assume okay. Do you all think those are good match for this plane?

My question is this, at what incidence should I install the floats? The Tango is a fun fly so she has a super fat wing (3”) that is perfectly symmetrical, she also has huge ailerons that are inline with the wing’s center line. A plane like this will not take off unless you increase your angle of attack substantially unlike a flat bottom trainer that will take off at speed. Should I do more then the usual 3 degrees of incidence for the floats? On the other hand I have a huge elevator that can pull down on the tail.

One more question as a fun fly she has rear mounted/exposed servos for elevator/rudder. What in the hey do I do for those? I guess I could make a quick water shield/blister to cover the servos. Can’t I just cover them with Vaseline and call it good? They are just the standard non digital servos.
