I swapped out to a Balsa Products 2212-13, APC 8-6 slow fly prop and also moved the CG back 1/8=3/16" behind the factory suggestion.

It gets off the grass better and is flying a little better with that prop and motor....and the motor only costs 15.95.


Where did you bought this motor ? I'm trying to find one from Great Hobbies because I am in Canada but they don't sell that brand. They do offer lot's of brand but since I know nothing in electric I don't know what substitution could be as good. I like the low cost motor as it could help me buy the outfit earlier. I have nothing in electric so I need to buy everything which increase the price of getting this plane.

Thank you,
Séb

Nice web site, thank you. What do you think of their ESC ? The recommended ESC with the Seawind EP is a 25 A but on this web site they only have 20 or 30A and seem to recommend the 20A for their Suppo 2212-13 motor. Is that right and what do you think of this kind of ESC and motor combination compare to the recommended combination made by Great Plane ? I could save a lot but I don't want to get cheap stuff.

Thanks,
Séb

Status: offline 		I have a dilema about my motor and batterie selection for my GP Seawind EP. I need advice about what is the best selection between theses two combo :

* Both from http://www.lightflightrc.com/

1) Suppo 2212-13 motor with 1320 Thunder Power 3s lipo batt.

OR

2) Suppo 2217-09 motor with 2100 Thunder Power 3s lipo batt.

So the first combo is really light but are ''maybe'' under powered ? While the second have lot's of power but it much more heavier, now will this extra weight cause problem ?

Here is the specs of the motors :

Suppo 2212-13 :
• 47g Mini Outrunner
• Kv: 1000, Rm: 0.090, io: 0.5A, Poles: 14
• Max watts: 145, Max amps: 12A for 60sec
• Shaft is 3.17mm
• Dimensions: 28mm x 30mm

Suppo 2217-09 :
• 70g Outrunner
• Kv: 950, Rm: 0.095, io: 0.9A, Poles: 14
• Max amps: 15A for 60sec
• Shaft is 4.0 mm
• Dimensions: 27.5mm x 30mm

* Specs of the original recommended GP motor are here : http://www.electrifly.com/powersystem/motors/motors-rimfire-28-30.html

And what is the weight of your motor ? If it balance perfectly with the 2100 TP and if your motor are not too much lighter than the bigger Suppo outrunner I may go with the second option. I am just a bit afraid of the complete flying weight.


* EDIT : I found your weight, it's the same 54gr. so my motor would be too heavy at 70gr.

Status: offline 		You're right. If the motor is 70g, I think you are going to need significant weight in the nose to balance. The location of the motor is behind the CG, so that is going to be a big factor.

Status: offline 		Thought I'd post some pics of the SeaWind at Lake Powell this last weekend. Bone stock per the plans running a 2100 battery which provides a easy 15 minutes of flying time running 1/2 to 3/4 throttle. I am making one mod after this first trip out. I'm adding some 2/56 bolts to the hatch to keep it secure. If you dink a landing the hatch flys off and you find your Seawind sitting in the lake with smoke coming out of the open hatch. Note to self, always keep a spare ESC in the box.

Status: offline 		Tried to maiden yesterday. Very calm conditions but the plane entered the ''skipping'' mode, then the canopy left the ship, resulting in a flooded Seawind... need more practice to master the take-off technique. I've also decided to use a screw to secure the canopy. Will try again later when conditions are less windy.

I think the same rule would apply to the way I take my catalina off... smooth increase in throttle and get her up quick!!

Status: offline 		Glad to report successful maiden yesterday. I practiced taxiing and take-off technique, once mastered it's very smooth. The plane glides beautifully and speed will lift it very quickly and gracefully.

A seaplane with a motor in this position is not responding like regular planes so it will take some time to get use to it. A few comments:

-This model is hot! Quite speedy and fast
-Ailerons were very responsive, had to use a lot of expo and reduce dual rate

On the overall I'm very satisfied with the Seawind EP! This one will be a keeper. Once you've sealed the wings and electronic equipment & secure the hatch no more water goes in. Also remember to put oil on the rods and maybe some lithium grease on the parts exposed to water.
