Mine is flying better than before with a 1320 in the nose and no extra weight.....some are doing fine even further back..the factory CG is indeed over conservative for competent flyers.

What kind of watts are you guys getting on a 1320?

I may decide to purchase a new one.

Nice!
I get down to TX (Little Elm) frequently, but I don't ever recall it being that calm.

I testfly my Seawind yesterday. No wind at all. Started from grass without any problem. CG located as the manual say, 25 mm from LE.

Seawind fly great at normal to high speed. At low speed Seawind drop down the air "like a stone". I have 12 mm at full up elevator.

What can I change so I can fly Seawind slower? It would be great e. g. to land at slow speed.

I do hope you anderstand my english?

Your English is fine- much better than my non-existent Swedish.

My Seawind flies quickly, it is a very sleek shape. I could slow it a bit and fly it at a high angle of attack with the motor adjusting the rate of decent.

I noticed my prop tips are also "bent" and it is not all that close to the fuselage that the clearance was needed. I liked the look of the spinner s I have not ries a replacement prop.

Tomas, Your Seawind is too nose heavy. The factory recommended location is very conservative. Move your Center of Gravity farther back and the plane will fly much slower and will not drop the nose on landings. I set my CG on the CF wing spars. You should be able to move your flight battery pack back about 1" and get this CG location. The only down side to a more rearward CG is that the elevator will be more sensitive and too much down elevator during inverted flight may cause a snap.

It's finally done!

I just submitted the formal review for the Seawind to RCGroups. Review should be published this next week some time. Here's a peek at one of the pics from the review.

Now I have my Seawinds CG moved back to the CF wing spars (42 mm from LE). To check the CG I have made a "flexi-CG-thing" for the balancing stand. See pic...
I like the stand, I can use it to other models just making an other pair of "flexi-CG-thing".

That is a pretty clever little extension Tomas.
How do you like flying the Seawind with the new CG?

Not a bad idea..larger models will likely need that upright finger at the front removed to enable the use of the CG stand on them.

I have had the Seawind out every weekend since it was completed until this one...

It was WINDY yesterday (15+ with gusts to 25) but our club had a float fly at the local Veteran's Center and I was itching to maiden my Seawind. I picked it up a few weeks ago but haven't had a chance to fly it until now.

Flying the recommended Rimfire 28-30-950 motor with a CC Thunderbird 18 and ThunderPower 1320. Plopped it in the water, taxied around a little bit, let it weathervane into the wind and slowly accelerated... got up on step, hit the elevator, and it was airborne in no time, flew great!

The motor has tons of power for this plane. Didn't have any trouble taking off from the water, it kept pretty level on its own (I did take care to laterally balance it beforehand). Water rudder wasn't terribly effective but good enough... I found that the key was to get up enough speed and hold up elevator to keep the rudder in the water while taxiing. I didn't have dual rates set up, I was flying with the high settings, and it was a bit twitchy, so on the next flight I added a decent amount of expo, especially on the elevator, and the controls were much more comfortable. Inside of the plane stayed dry, no problems there either.

The wind and choppy water were absolute non-issues! It handled the wind with flying colors, I and everyone there was just amazed that it flew so well in such crummy conditions.

Loved it! Can't wait to get it on the water again! Can't say enough good things about it...
