Tail Wagging:
I wonder why Horizon didn't use AS3X for this?

I couldn't move them but they run across the plastic? One on each side.
I also haven't noticed any trouble with the Gray fairing on the fuse in front of the motor. Mine won't budge so I don't think it will come off during flight.
Don't worry -- no cracks, those are in all of them. I'm on my second fuselage (learning curve ). On my first fuse, the method they were using to glue that fairing on was with hard glue and it cracked off easily. I lost mine on takeoff as it blew through the prop.

On my second fuse, I noticed they changed their method and are using that soft white caulk like glue and it holds much better. I pulled it off anyway and reglued it with clear silicon but it was definitely manufactured much better. I think they must be listening to this forum!

Thanks for the reply!

I flew the Icon today at the field, still too windy on the bay for a water takeoff and the tail wag was TERRIBLE! Every time I came out of a hard bank turn it wagged like a dog waiting for a treat!

I've ordered 3MM Carbon Rod that I'll run along the fuse to the tail on either side to stiffen it. If that doesn't take most of it out I'll buy the Gyro from HK.
I like the plane but the tail wag is unnerving to say the least.

Would I have still bought the plane if I had a chance to fly it first? .....
Probably not.

save yourself to $$ on the carbon rod... this issue is the lack of airflow over the tail when coming off the throttle, or more specifically, the lack of air flow. I have used a gopro facing the tail and there is very little play in the tail in relation to the fuse... acutally the wings move more than the tail... I posted the video awhile ago a few pages back about this... you do have a couple solutions though... you already mentioned a gyro, i have done this but you may want to look into getting a stronger servo for your rudder... I burned mine out after about 20 flights..., so after pulling my gyro and replacing my servo I have started doing what some of the guys on here have talked about... very briefly give a little bit of left or right rudder when you get that dutch roll effect.. and the plane straightens out real quick... it puts some pressure on the vertical stab and while you may have a small knife edge effect for a second... it settles the plane down.. especially during landing.

the real question is how this issue passed QC during testing... but thats a whole other can of worms!

regardless love this plane though... i would have still bought it ahead time if I had known.. but I live near alot of water and almost never use the landing gear...

When I find that vid I will repost it.

I disconnected the rudder servo from the receiver and tried to move it with my fingers and that sucker was locked up, would not move. I finally decided I've got nothing to lose so I forced the servo arm and it actually jumped a tooth on the gear. Still totally locked up.

Packed up and went home, when I got home I removed the servo from the airplane and tried it again. Totally frozen. So I took the cover off of it and looked for any trouble. I couldn't see any problems so I plugged it into the receiver without the cover on it and what do you know? It worked just fine.

I then put the cover and horn back on and it seems to be working fine now. I'm not planning on putting it back in the airplane, I'll use something else instead. Fairly frustrated that I didn't get to enjoy the nice day with it yesterday. I did go home, grab some other planes, and go to the club field. So, at least I got to fly.

I wanted to follow this up. I looked through my servos I had laying around and didn't find anything that was going to fit perfectly, so I talked myself into putting the stock servo back. I used hot glue and sealed all the way around it so there's no way water could get in, except through the output shaft hole, which is elevated. The Icon doesn't get more than a couple drops of water in it anyway, so I think I'll be fine. I have about 10 flights on it since the rudder servo was locked and it seems to be fine. I will report back if anything funky happens.

Thanks Ayeager ...
I flew the plane again today from land (blowing 20 knots across the bay here at the Jersey Shore) and the plane flew different (?). The wind was 6 to 8 with some 12 mph gusts and the wag was considerably less. Yesterday was calm at 3 to 4 mph. The planes seems to like the wind (what plane doesn't) and carved thru it nicely. I could see it wag once in a while but not as bad as yesterday.
I did use some rudder in the turns and they were pretty smooth.
Looks like I climbed on the soapbox too soon

When I mentioned adding carbon rods to the tail one recommendation from a club member was to run struts from the fuse to the underside of the stab.
I have the pads and clips to do this and it would definately stiffen the tail and keep it from flexing. I don't know about others but I can move the tail on my Icon a good 1/4" side to side with very little effort. I used silicone glue at the fuse/tail joint but it didn't help.

I cannot wait for a calm water day so I can fly it as it was intended. I live right on the bay here and bought this for that sole purpose as our club is a 40 minute drive. It's saltwater and I put foam in the air intake as suggested earlier and changed the canopy gasket to a ribbed type we use to seal boat hatches at work. I will get some corrosion inhibitor spray for the electronics as well to keep the inevitable to a minimum.

Thanks again for the replies, the planes a looker and grew on me big time after the flights this morning!

Looking forward to taking my A5 down to the Outer Banks of North Carolina soon and flying off the quiet saltwater Sound. Should be fun if I can keep the saltwater out! Good idea about the intake foam. I missed that one. What type? Any other suggestions?
Thanks

Protect your electronics from Salt... Salt is a real killer. If you can, put your receiver in a air/water tight package as well as your ESC. Seal your servos as well if you can.

I have been twinkering around with mine.
I want to add flaps to the wings, Any one have a "How-To". I'm ferly new to this hobby on the aspect of building and modifying.

1. What servo's to use Hitec HS-55,HS-65HB,HS-65MG?

At least a 65 I would say. 55's are not that strong. Also, be sure to find some way to seal them from moisture.

I cut a piece of foam found in Pelican Cases. I use those cases for my amplifier tubes.
The foam is very porous and will block the water from entering while allowing some air flow for cooling. Hope this helps.

PS: camera cases use a similar material.

So, i have around ~60 flights on my A5 and today i had a major problem. For some reason it took way too long to take off (60-80ft). Dead clam, no winds today. I have 7 batteries and it did the same for all of them. It flew perfect the last time i took it out.

The field i go to is a grass runway. I was barely able to make it off the ground before i hit the non-mowed area.

Could the motor be going bad already (prop is on correct way, and i use the landing gear)?
