Title: Flyzone Scale Seawind Amphibious seaplane
Post by: Oscar on November 09, 2015, 04:57:46 PM
Runs on 1800/2200mah 3S.
Comes with retracts, nav lights, flaps.

When retract is up, it will drop down the water rudder. (Retract down, water rudder will goes up)

Very nice... Will it unseat the Beaver as the Flyzone float plane of choice this summer?

Love the Seawind, but for now I'm going to continue trying to resurrect my discontinued Electrifly Seawind (39"ws). If the Flyzone retracts work well in the water and on land, I'll probably give the bigger size a try.
I looked at the Great Planes version hanging in A&Js but the reputation of this one was not good, AJs price tag was high and an electric conversion would be needed...so many great toys, so little time!
The Seawind has always been a favourite of mine...I love the lines. For a couple of months this summer, there was a full size one parked at Buttonville with a really great colour scheme. It's got Canadian registration and the paint scheme is better than Flyzone's. Photo below is FYB parked on the apron at Buttonville this summer... beautiful airplane!
As an interesting aside, a few years ago, my cousin was almost killed in a Seawind. He owned the aircraft and was taking off to take the aircraft to an auction to sell it. Engine failed on take off and the plane hit power lines as it descended and crashed onto a road, main gear punched up through the wings, puncturing the fuel tanks and spewing av gas all over the road as the aircraft slid along. Spark, poof, inferno! My cousin popped the canopy and was out, just in the nick of time!
Sadly the story had an unhappy ending...no insurance!

Saw this plane at the recent NEAT Fair. Beauty! Didn't see it fly, don't know if it did, but it's a beauty! Nice size with flaps AND retracts. It's definitely on my Xmas wish list.

Just spoke to Pinnacle.  The Flyzone Seawind (FLZA4054) will cost around $320 (may change due to exchange rate).  I wonder if we have enough people to perform group buy, maybe Pinnacle can give us a good deal.  The Flyzone Seawind is selling as Receiver ready.  In HH term, it's PNP basic. (no R/X, no charger, no battery).  Battery size the common 3S 2200mah. 

I found some videos from YouTube on this plane.

Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Michael on December 18, 2015, 02:52:39 PM
It appears you were flying downwind (with the wind).

Were you flying slowly?

Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Oscar on December 18, 2015, 03:00:15 PM
Just over 1/2 throttle. There was no wind that morning.  Lemon R/X full range with Satellite in DSMX.  Same R/x in B-17, Skymule.  Radio is Spektrum RX9. 
Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Michael on December 18, 2015, 03:08:41 PM
If there was no wind, then my concern about a downwind stall are wrong.

I don't know why you crashed.
Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Wingnutz on December 18, 2015, 04:46:05 PM
Oscar, FWIW, my two cents worth based on the zoomed  video and four years flying Electrifly's Seawind...
I think Michael was hasty dismissing his stall theory...to me, what I can see looks like a spin which starts with a stall of one wing...usually precipitated by flying too slowly...easy to do when the  downwind model speed you see is much higher than the airspeed the model experiences.  You said there was no wind, but at the model's altitude, there was probably more than on the ground...how much more? Significant enough to fool an experienced RC pilot like you? On a maiden flight, maybe.
My Seawinds (I've had two) are not relaxing models to fly...once they start to roll, they do not self correct and the roll will increase if not corrected with control inputs. I've never spun the model on purpose but suspect it would not self correct like many models do when control sticks are released.
Maybe it's the fact the motor's mass is so much higher than the CG that causes the model to be an enthusiastic roller but whatever the cause of the problem, my practise when flying my Seawind is to follow Michael's "How Not To Crash" lecture advice...keep the model in close where orientation is less of a problem...AND correct or control roll as soon as you encounter it.
Good luck with the rebuilt model!

Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Frank v B on December 18, 2015, 07:50:31 PM
Oscar.... sorry to hear/see.  Please send me a photo of the pieces so I can help you rebuild it or at least offer some advice.  If it is even remotely re-buildable and you do not feel up to it, I will do it for you.

One thing to add to the Michael/Nutz* explanation.  The prop is a tractor and is fitted to the tail.  That means elevator/rudder inputs will be OK while the prop is spinning but there is no prop wash over the wings at all.  This affects both lift and aileron control dramatically.  The problem is that since you keep distinct elevator and rudder control you forget that the wings/ailerons are becoming ineffective.

This plane should be treated as a jet (no wash over any tail surfaces) and needs to land hot.  This plane has a lot of volume and, I suspect, little weight so it would slow down quickly and dramatically.  Much like those of us who have dented the earth with the E-Flite Brio 10. If you ever came near the ground and throttled back or shut off the motor, it would lose speed so fast that it would flutter into the ground.  Trust me.  I did it twice!... just to make sure I was stupid! ;D

I had a similar scare with Malcolm's little flying boat that had a pusher prop on a pylon at the trailing edge of the wing.  Elevator inputs were always sensitive but aileron control was scary when throttling back.  I came in hot every time because it was a small plane. That probably saved it.... without me knowing it.

I learned something today.  Thanks Oscar.

Frank

Sorry to hear about your seawind, Oscar.  A time lapse video of the repair would make an it interesting!

You mentioned there were two pilots also appeared to have lost total control of their model and crashed at/near that spot earlier that morning. One of the crashed model was also a pusher and I'm not sure about the other one. So the tail wind stall theory as offered in the previous posts may not be that far off. Windless condition at ground level may have fooled more than one pilot that morning...

HI guys,

Anymore theories/updates on the crash of the Seawind? I picked one up this past Mon., and have installed rx, battery and bound it. Don't know when I'll get to fly it what with the snow and all. She is a beaut!
A fellow on you tube added Parlzone vortex generators to his Seawind wings. Don't know if they improve flight characteristics, but they look neat. The same fellow has the C of G 2.75" from the le.

Hi John

Yes, I spoke to Glenn (https://www.youtube.com/user/mnragnar) who has the Vortex generator installed.  He said it's night and day.  When I have my Seawind rebuild, I will put the vortex generator on too.  He also mention setup in crow so it can land in show distance.

My Seawind rebuild completed.   I added the vortex generator onto the wing, a new pilot  and a new decal  ;D

Crow? What is crow and how does one set up?

Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Oscar on February 08, 2016, 03:11:17 PM
Borrow from http://www.rc-airplane-world.com/rc-glider-wing-setups.html
"Crow : also called 'Butterfly', RC glider wing function is used when landing. When Crow is activated the flaps drop down and the ailerons move upwards. This gives a very effective combination of drag from the flaps and reduced lift from the ailerons, now acting as spoilers. The result is that a fast-flying glider can be slowed right down and, when landed well, can be brought in with very little forward airspeed.

It's common for crow braking to be operated by the throttle stick of the Tx, although having it on a switch or slider is perfectly acceptable. It's also usually necessary to mix some degree of elevator compensation with crow braking; a glider will likely pitch upwards, sometimes drastically, when crow is activated and having the elevators deflect downwards automatically is very helpful."

Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Oscar on February 08, 2016, 11:19:52 PM
Thanks Bruce, I think the pilot watched my crash video.  ;D

The fuselage is new as well the horizontal stabilizer and the canopy.  Others are from the old plane (gluing them back).  One of the challenge is putting the gears and the electronics back.  Unlike other fuselage, I found this plane has very limited space.  (Number of times I almost give up and thinking I might as well buy a new one instead)    :P

Title: Re: Flyzone Scale Seawind Amphibious seaplane
Post by: Bigstik on February 10, 2016, 03:00:22 PM
It's a beauty of a plane, but I find the non removable canopy an issue. There is so many wires to cram in behind the seat, that a removable canopy would be much easier. I'm thinking about it!

Photos of my cousin's 2013 crash of his full size  Seawind were snapped by bystanders as my cousin tried to make an emergency landing in Fort Nelson BC with the plane already on fire and the engine stopped. The full size airplane has a troubled history and Oscar, in terms of crashing Seawinds, you are not alone. Good luck with the re-maiden!

First float fly for me in 2016. Wind was calm. Beautiful sunset.  Perfect for first water flight.

First flight bumpy take off and landing. Thank you Bruce for helping me trimming the plane. On landing, unlike the Apprentice or the Tidewater, it bounce (like the HK skipper) and end up collide onto Gerry's Tide water. No damage for both plane. 

Second flight it didn't goes well. Bounce number of time and end up dive into the water. Thank you Rob for helping me retrieving my Seawind. Water filled the fuselage. 

Thank you for the advise from Rob, Glenn and Bill - lesson learnt. (Full up elevator while take off on Seawind)
