What, no pictures? Could a fellow like me get a full size set of plans for your creature? It sounds interesting.

In February, you mentioned you thought there were still several un-built Seamaster 120s around. Do you know of any specifically? Mine fly really nice and a couple of our club members are looking for one.

Thanks,

Tom

I didn' think about using a FS 91 in a Sea Dancer, but if I build another one, I think I'll take your suggestion. I have a Magnum 91 FS just sitting in a cupboard. Larry

Well,I don`t know what the others did with the Seamaster. My Seamaster,made yesterday is first and second flight,and I didn`t found any problem at all. It`s staight from the box, no changes at all. It weight`s 16 pound`s (8 kg) powered with a simple ASP 1.08 2 strokes, 14/7 prop. It`s easy to fly and land .No problem at all. Just follow the instructions. I read this articles before the flight and I become afraight. I`ll never do it again. Sorry but the airplane don`t need any changes. The tail works perfect.

How about some sort of twin engine variant of the Lanier Mariner with the engines in the wing rather than up in a pod? I suppose you would be limiting yourself to the intersection of two smaller markets (people that do both floats and twins) but it would be a really cool bird.

Dang -- this post has hung on for a while. Mac asked about a picture of RCM's Sea Dancer (plan 1214):

Looks a bit like the Sig Sealane I've about finished.
Does that help, fellers?

I just purchased a 120 seamaster kit and it is being shipped to me. I have been reading all the e-mails and I am reading about this yaw problem and one e-mail said it flew terrible. I am not a scratch builder. I like to work from plans and an instruction book. Is their any easy modification to fix the problem. One person wrote about attaching 2 vertical fins on the stabilizer. Any suggestions!

Hi Scott

I just purchased a 120 seamaster off RC universe from a person in MO. I have been reading all the e-mails regarding the Seamaster and this Yaw problem. And then I read another e-mail and the guy says he does not know what everybody is talking about his flies great with no modifications. Should I be concerned?

Tony

How is your seamaster flying?

Never had a yaw issue with the smaller one but definitely saw it in the big one a fellow flier had. It was very obvious. I had the notion that shimming the engine to thrust to the side of the yaw might help. I think his yawed to the right and I wonder if the torque of the big engine (ST3500) was twisting the pylon to the left or perhaps it just torque itself was causing it witout any pylon twist. Of course the ST3500 is almost double the size of a 1.20. Perhaps it wouldn't happen with the smaller engine.

I bought a SEAMASTER sea plane at a swap meet two weeks ago. It is supposed to use a 46 engine which I have installed. I think it was an ARF. It is construcred from balsa and ply and covered with monocoat. It has a high tail. Does anyone know who made this plane?

The Seamaster kit is made by Ace.

The yaw problem is not a big deal. A little differential aileron and/or some rudder mixing (30%) should take care of it.

What I saw was not a case of adverse or proverse yaw in turns. The airplane flew yawed in a straight line. Whether it is inherent in the design or construction error I can't say but there were basic alignment issues rather than control ones.

If anyone is interested I have the Ace Seamaster 120 in restoration phase and would be interested in selling it. If interested please e-mail me at [email protected]

Thanks,
