Help!
Old Seamaster question

I have an old Seamaster (I think a Ken Willard design) that I got from a friend who put it into a tree. I have fixed all the damage and now in the process of putting it back together and getting it covered. My question is, what should be the incidence be between the wing and tail? Should both be zero? The way it sits right now or the way it was originally built, if the wing is at +2 1/2 degrees the tail is close to zero. Seeing that it is still in pieces I can fix the incidence now before gluing the tail back on. Most all of my other planes the wing and tail are at zero. I did set up a Cub on floats and I know that there is about a +2 degrees between the wing and the floats. My guess would be that the wing & tail should be zero just like my other planes, but not sure.
Thanks, Jeff

Heya Jeff,
I don't have experience with that model directly but may offer a little advice.

Most seaplane models I've come across seem to have a little positive on the wing, 2.5 deg sounds about right.
It seems to help lift off the water easier without having to rotate all the way through to the AOA needed for take off. The converse is that it does have a sweet spot on the throttle, above which it will balloon when in flight unless you add a bit of down elevator.

I'd be inclined to leave it as is.

Any idea who made this kit? From the plans that pookielips1954 gave a link to it doesn't seem to be that plane. It was built not an ARF, has a 60" wing span and had a 60 size glow motor in it when my friend got it. He converted it to electric and I plan on keeping it that way.
Thanks, Jeff

The original kit yours was built from was made by Ace RC from Higginsville, MO.
The ARF was made (very well) by Thunder Tiger, now sadly out of production.
There is now a new lighter built clone called a Neptune, made by a different outfit, that looks very similar.
