If i'd felt resistance of any degree, i would've run a tap through
the nut let go pretty much without any sign... if i'd put a threading tap into it, the nut still would've let go, then i would have had to make a scale antenna out of the tap sticking up out of the tail

just a word of caution on the blind nuts in the tail

are the "plates" something along the lines of additional planing strakes, to help get up on top of the water?

I am kinda tempted to perhaps add to the sides of the sponsons just to see if that'll aid in the "wing tip in the water lean", but i think to stop the leaning over, the size of the foam would end up with the plane looking like a strange bi-plane lol
i'll wait until after i've flown it a few times, to see what adverse effects sponson extensions has on flight performance

I suppose that Ebifuryaa fitted plates on front edges of the sidesfloats (sidesponson, side sponsons?) not to suffer from water.
This way is another one.

As mentioned Junger Be #10 in this thread, water goes up along fuselage surface (as represented “overflowing” in #10) before planing. This causes hard to move planing. To prevent this situation Junger Be attached sidestabs or plasticstrips; show #10 pictures.
I wonder plasticstrips are needed every float.

To Lancer31

Thanks a lot for your information and your opinions.

Using a wing-leveler, I agree with you that rate-gyro is the best, too. Nowadays rate-gyro’s weight is 30 gram or so. This means we can put smaller plane on. But none of our member wants to mount it, because of our principle; more simple and less cost. I think this judgment limits under 700 gram plane, as like smaller ICON-A5. Of course for bigger one is no problem. I’d like to mount rate-gyro for large ICON-A5. Thank you for your advice.
Also I’ve been enjoying R/C heli around two decades, electric and gas, from 450 class to .90 class (for F3C competition). So I think I know well which item is better for use. (Sorry a little bit proud )

BTW a handle name “seeker-shige or seeker” is also me, sorry too.
Those footages were edited by me. Please vote those footages good!.

Thank you.

Such a system could consist of a single rate-gyro, which can be switched on or off, to control the aileron servos, during takeoff & landing phases. The "magic" trick of a wing-leveler is that its gyro-axis is canted exactly 55 degrees up, with respect to the horizontal centerline of the fuselage. What that does is to respond to any gust-caused upset of the model, whether in the yaw or roll mode, and give aileron to correct it.

While it may well be necessary to add spray-rails to the bow edges, to help control how the water reacts with the hull, and maybe greater span/volume to the sponsons, a wing-leveler system has the advantage of being able to respond instantly to the problem! (Even faster than Shigetyann, and his good-flying racer friends, especially when it is 0 degrees C, at the pond)!
Nice! It will be interesting to see your results!

The problem I am seeing though is during low speed taxi, I can't seem to turn the Icon into the wind for take-off. And by wind, I mean even a 5mph wind! The wing will also dig into the water causing more of a problem in trying to turn or even accelerate to take-off speed. I assume this system will only work once the plane has started to move a bit? Or will the prop wash cause the wings to stabilize at very slow speed?

That rate gyro sounds like a cunning stunt (dont swap that around) will give it a go

Try going a bit faster , so youve got more airflow and water rudder response

Once the little bit of wind catches the wing and gets up under it, the opposing wing tip digs into the water and keeps me from going anywhere. If I try to speed up the Icon just spins around the wingtip thats in the water. I think wing sponsons would help?!

Try going faster when the wings are level , then you should have better control

Thanks, understood, it just takes awhile to get the wings level so speed can be increased. See ssatoru post also as he had similar problems. http://www.rcgroups.com/forums/showp...&postcount=145
