Status: offline 		Hey guys, My seawind is up for sale on RCU. Only flown it 3 times. still in great shape. I've just lost interest in the plane and want to move onto something larger. If anyone is interested, I will be going to the Toledo Show in a few weeks. I would be happy to bring the plane there if I had an offer.

I repared it with Fiberglass and added a little extra fiberglass to that "V" area and haven't had a problem since.

Status: offline 		Hi all
Could i have some advice please

I flew my Seawind in the Summer with a Saito 125 until I noticed some cracks appearing from under the pod. I am now repairing it and fitting Robarts but have noticed a couple of other things. There is a couple of splits on top of the fin and when I flex the pod (looking inside the Fus) i notice that the wooden shoehorn support coming up from the pod is flexing. Should this be glued or is it designed to move. See picture, its the wooden part you can see through the stringer. Any help with these points would be appreciated.

The Saito 125 4 stroke has a lot of power and vibration. When revving engine on the ground tether plane by attaching the tether around the fin underneath the engine nacelle. If you hold the fuse at the nose while revving engine it puts all the stress on the fin and also the fuse at the bottom of the fin.

Status: offline 		Hey Asnook: I think the motor you're using is putting way too much stress on that pod which was weak to begin with. I'm betting you had to put a lot of weight up in the nose to offset the weight of the engine. I flew mine with a Magnum .91 4 stroke and had no problems. This plane has a pretty high wing loading factor to begin with and adding weight to it doesn't help it at all. Might want to dial down the power. I also flew mine with retacts.

Status: offline 		Norm, as well as anyone that can help. I have been studying your forum for sometime.
My question is: Does anyone have good photos of where these aircraft are coming apart? After the crash type damage....not to stirr painful memories.....but, it would help me to see where and how to reinforce.
I would like to reinforce as necessary with Kevlar. Does anyone have thoughts on my thoughts?
Also, the discussion about the skeg? Somewhere on the bottom? I read the discussions on the matter, but i am just a duh kinda guy and I just can't picture it. I could really use some photos on that as well. Maybe include the cut off rudder to. Thank you for your time. Allen Wilcox. In Vermont, winter is nearing an end....Yeah!

Status: offline 		Allen, re-inforcing the tail boom with kevlar is a very good idea. Maybe your plane will last longer. I would try to place a peice of kevlar along the hinge line in the rudder. What GP used there was just ordinary balsa wood. That point usually breaks first. The plane needs a internal frame work from the engine to the fuselage somehow to make that area more rigid.
From my past experience, the more mods you do, the worse it gets. The plane is already super tail heavy just adding more weight to the tail will kill it. If I were to get another one, I wouldn't do much to it and just fly it very gently. When you land it make sure that you land very softly so it wont bounce - The engine pod is very flexible and will crack or break if it is landed hard. Hard high G acrobatics will do the same thing to it too. Believe me, I found out the hard, expensive way. Some guys are going electric and that is a very good idea for this plane. The least amount of weight up in that engine pod the better. Good luck with that seawind, have lots of patience. They are the prettiest planes in the air in my opinion although they are very tricky to land and take off.

Status: offline 		Hi Seawind Buddies,

I enjoy flying my Seawind, it is great in the air and causes heads to turn. Everything on my Seawind is exactly as Great Planes instruct with one exception: I have velcro attached polystyrene tip floats a la Seamaster. This makes take off uneventful following the technique suggested by earlier posts (spool up the throttle holding up until on step) I don't think the floats look out of place, although clearly not scale. See photo. Landings are still somewhat of an arrival, with bounce which will obviously take its toll on the frame evenually. Now my question: please can someone talk me down? I have flaps.

Status: offline 		The key is that the angle of attack of the fuselage bottom has to be perfect. The step and the tip of the tail must touch the water at the same time. That only happens at one speed, so the speed of touchdown is the critical parameter. Too fast and the step touches first and you bounce. Too slow and the tail touches first and you bounce. Just the right speed and you grease it. Don't feel bad, nobody does it right every time.

edit: this is a nitroplanes seawind here, but it looks just exactly like a great planes seawind and the trouble i had was the vertical stabilizer pushed down into the body of the plane.
