I noticed today right before I was about to start the motor that my Seesaw was broken. I havne't crashed it or had any hard landings.

Has anyone else had this issue?

They are pretty flimsy. I have broken several in crashes, but not without crashing. You may have a bind somewhere, possibly

I checked for binds and found none. Heli is flying great. I just happened to notice before I started. I've broken one in a crash as well.

I'll replace it and if it happens again, go with the aluminum one I guess.

LOL...that is even more odd than the seesaw breaking. What happened?

The breaking of the flybar in flight isn't as odd as you might think, I had one break a year ago....Breaking Flybar

Is that a 6s 5000 in your pocket,
or are you just happy to see me?

ive looked into this pretty extensively, for the evo no. for the std. sceadu there was one but i wouldnt buy it. i think it would be a worthwhile upgrade, mine bend just looking at them =\

i was thinking about that too, honestly i dont know. in the std. sceadu, the bearings are damn small as it is; so im not sure if that would be a possibility.

Don't know for sure. It hadn't been in a crash or anything like that but was probably a year old and I don't know how many cases of fuel. It was my third flight of the day and second flight of doing mostly just snakes. Then I shot an auto and as the head was spooling down it started shaking bad on the blacktop and settled down. Then I saw half the flybar was gone. A friend of mine said he saw something fly off and flutter to the ground at the start of the auto but didn't think much of it since it landed ok. He thought it must have just been a bird flying around. I'm guessing the failure was mostly due to the amount of time on that part and it finally had enough. I plan to arbitrarily replace them once a year.

Thanks for the heads up on that.

I don't know that it will do me much good right now though. I doubt I will get even close to a year before having to replace it [from a crash]

I admire you for being able to go that long on parts. What other parts did you find during that time that wore out?

Thanks, I try to fly within my abilities and build everything up from the basics.

These are what I have found:

The usual clunk line, dampeners, etc.

Ball links, I replace the metal link balls on the tail often when the season is in full swing.

Even if you don't crash it you should check all the bearings along the clutch shaft, rotor shaft, and all in the tail rotor a few times a year.

Notice if the clutch takes higher throttle to engage and replace the liner. I replace the clutch shoe also.

Had a one-way fail but my other sceadu with more time on it is still going strong. I epoxy them in to their housing with 5-minute epoxy.

It has been relatively maintenance free. I think the things listed are common among all models. I screw with it less than I have other models. You can't plan for everything. I had an RX fail which circumvented my preventative maintenance. So you can't really win against these things.

4mm Fly-Bar Evo-50

I know some people have done this. I just checked you would need 2 x 4mm X 7mm bearings, found several on Boca's site. 4mm fly-bar will go through the stock see-saw, but it rubs, need to drill a tiny bit for clerance. Drill the two aluminum fly-bar control inserts and a 4mm should slide right in. Need to find or make a 4mm fly-bar the length you want and paddles.
