    Sig Sealane CG and control throws?

    Hi All,
    I recently bought a Sealane at an estate sale. I need to find out the throws and CG location. Sig has the instruction book online but it refers to the plans for the throws and CG location.
    Thanks for any help you can give.
    Jim

    RE: Sig Sealane CG and control throws?

    Hi Jim
    I can try helping you, but first we need to know what kinda seaplane you have? I know it's a Sig, is it a flying boat type or a float plane?

    Looked down in the basement and determined that the plans must be up in the shed, will look later for you. Just an FYI, the SIG Sealane will need "chines" installed to aid in getting it up on "plane", without it is a real dog to get it off the water. Installed chines on mine this winter and hope to test them out soon.

    RE: Sig Sealane CG and control throws?

    Would have been back sooner, tackled by the wife for a couple of "honey do " things.

    Airlerons - 7/16" up/down

    Elevator - 1/2" up/down

    Rudder - 1-1/4" left/right

    Good luck.

    RE: Sig Sealane CG and control throws?

    Thank you Lamoilleriver. I appreciate the help. Do you know where the CG is supposed to be? I've read several posts that recomend adding the chines. I was going to try to fly it once then decide what I needed to do. I was planning to do something similar to my Lanier Mariner to make the belly wider and deflect the spray.
    Thanks again for the help,
    Jim

    Hi Wetbird,
    That was SeaLane not SeaPLane. But thanks for the response and the offer to help.

    Back up in the shed in the morning and I will take a peek at the plans again, pretty sure it is right on the main spar, but will get you an exact measurement.

    The CG is 3 - 1/4" from the leading edge, which is exactly the center of the spar.

    RE: Sig Sealane CG and control throws?

    I flew it last weekend. It flew great. It needed quite a bit of down trim. I need to recheck the CG. I may have got it foreword a little too far. Hanging upside down on the CG machine with the engine pod down, it takes a lot of weight just to get it to rock a little.
    On the water, the lake was fairly smooth but not glassy. With the 46FX and a 3 blade prop (10-7) it climbed right up on step and jumped off the water. Once it was trimmed it flew great with no bad habits. Landing was a piece of cake. It did not want to bury the nose in the water like many sea planes I've seen. I held full up elevator until it got up on step, relaxed the elevator to pick up speed, then a little up to fly it off. I'm not ready to modify the bottom yet until I try it on choppier water. The kit is 103 bucks from Sig. Seems like a good deal. I'd build one.
    Jim
