Sig SeaLane building tips and considerations

I a have just ordered a Sig Sealane, and will begin building shortly.
I will be installing an OS 40 LA (which was formerly pulling a LT-40
with authority), and I will install a Futaba 4 Channel with standard
servos.

I have never flown off of water before, and I have never built a
watertight craft before. I am seeking advice regarding the best type
of components to use, such as pinned vs. nylon hinges, and effective
construction and waterproofing techniques.

Also, anyone familiar with this particular craft may be able to
suggest a good prop size or type (9" or 10", 3 blades or two?). Any
tips on balance?

Thanks-

Re: Sig SeaLane building tips and considerations

One tip when flying off water is to have sufficient power. The Sealane is
designed for a .40 size engine but an OS 40LA would not be my choice. You
need ample power to break the surface friction of the water and I would
strongly suggest a more powerful 46 size engine. In the air, float planes
also have more drag due to those appendages hanging from the wing and the
external power pod. Standard hinges are all that are required. The hull
should obviously be waterproof and this is best achieved by ensuring that
all joints are tight and sealed. during construction and that your finishing
method ensures no water gets into the wood or inside the hull. I prefer
several coats of finishing resin and then paint for the hull. Try to mount
your radio switch where it is least exposed to spray. A two bladed 10-6 to
11-6 prop is adequate for a 40 to 46 size engine. When you're ready, pick
the right day (morning) with just a tiny ripple on the water.

That may be in the wings in the near future- as is a blackwidowav
camera setup- but for now, I must try to limp with a 40 LA. This
engine pulled my LT-40 nicely with a 9X6- my fingers are crossed. I
went ahead and ordered a 8x6 3 blader- but I think that I will pick up
a 10X6 per your suggestion.

Damn- I have already ordered monocote. Forgive my ignorance- what is
finishing resin? Does the paint need to be fuel proof? If so, what
paint is waterproof AND fuel proof?

Thanks for your advice- Barring death or hospitalization, this
project will go on the bench this week.

Thanks! ~Sisyphus

You can use MonoKote or any other covering material, UltraCote etc. Just be sure the seams over lap by at least 3/8 of an inche. It will water proof your Sealane. BTW, are you going to install the optional wheels for land flying or just fly off of water?
