Is this behaviour normal for co-axials?

[gadgetgaz]

When flying the Mini Twister Scale and I let go of the cyclic controls it stops whatever it was doing and comes to a rest - almost. It's obvious that it is trying to come to a rest but what it actually does is stops and swings back again in the opposite direction it was flying for a few feet.

The same things happens if it is in a stable hover and then I move it sideways, say to the right, a few feet and let go of the cyclic it will stop moving to the right and then swing back left again - nearly ending up where it started from.

I know the flybar is meant to do something to stabilise the heli but it seems to way overcompensate.

Is this a normal response for a co-axial?

Yes, I think so. My Big Lama was like that.
Also gets a sideways wobble going if you try to go fast forward, or quickly stop from forward.
Think its just a co-ax thing!

No, I haven't seen this in any co-ax's I've flown. Try adjusting main blade tightness as I noticed this had an affect on flight, although no where near what you said.

Thanks for the input guys. Reading around the subject I guess what I am describing is the pendulum effect that seems to be common to flybar helis so it might not be a co-axial trait so much as a flybar trait.

LaurenceGough, I can't alter the blade tightness on this model because they are fixed and I have slackened the flybar mounting well off so there is no noticeable binding. The model sits still in the hover with very little input so the 'problem' is only noticeable after some cyclic control. I just have to counteract the involuntary movement with some opposite cyclic control.

Coax's are designed to be stable so they are easy to learn with, as was the old Blade msr - pendulum effect is a result of overcomphensation but also a product of the flybar system.
Nothing to worry about because it's helping to prepare you for the future.

co-axles were made to be steady and what ive seen in videos is that you can put the transmitter down with the sticks in the right place and it will stay there until the battery runs out
