I bought a Hirobo Sceadu Evolution 50 last year from a friend and love every bit of it. However, when I looked at the Swash plate (its blue, I think this means its an aluminum upgrade) when I apply FULL aileron AND elevator, the swashplate binds. All the linkages are exact, and all the ball links are in good working order. Full aileron doesn't cause it to bind, and Full elevator doesn't cause it to bind. Only when the two are used together does it bind. The collective has no impact on any of this (doesn't make it worse or better). Any ideas?

If you have the ccpm version you can just adjust your swash mix in the TX to lower it a bit so it doesn't bind. That's the easy fix/ You can always play a bit with your endpoint adjustments on both of them if you want to do it this way.

Another thing they sell is the round discs you can put on your right stick for your Tx which does exactly this, not allow you to overdrive your servos. Your swash is round but the travel of your stick is actually rectangular. Not proportional to the swash. That disk takes care of that.

Hope this helps.

Its called a cyclic ring and thats the way to go. Otherwise you will loose a little bit of throw which depending how you fly may not even be a big deal.

I have the "manual-mixing-way" and I think I'll just lower the end points from the radio I don't think I'll be using those insane amounts of cyclic anytime soon. Doesn't a stalled digital servo take around 1 amp of power?

Thanks for the help guys!

This is RC helis' version of the old joke:

Doctor, Doctor ... it hurst when I do this!!!

Well then ... don't do that ...

So ... don't put your cyclic stick in the corner ... problem solved.

This is not unique to your heli. Almost all heli mechanics will bind if you put the stick in the corners. It's common but unwelcome. The cyclic "rings" that barracudahockey mentioned attaches to the TX around the cyclic stick and retricts you from putting the stick in the corners.

That's because the TX stick is made to work for airplanes. Note that its range of motion is a square. You can move the ailerons full blast and that's entirely separate from the elevator, which can simultaneously be moved full blast. But on a heli we don't have two separate gadgets connected to that stick, we have only one thing, the swash. It can tilt just so far in any direction. Its range of motion is bounded by a circle rather than a square. If you have the endpoints set to max for aileron only and elevator only, then you have a situation like this... the circular limit of the swash is INSIDE of the square of the TX control. This means that when you move the TX stick into a corner you're outside the range of the circle and binding happens. The "cyclic ring" keeps the TX stick within the circle. Alternatively, you can reduce the aileron/elevator to about 70% of max, which put the square of the TX stick INSIDE of the circular limit of the swash. In that case the corners don't exceed the limit of the swash, but you don't have max control otherwise. That's no big loss unless you want all you can get out of it.
