Just seen Infinavation dampers for the Synergy on realraptor.co.uk website : http://www.realraptors.co.uk/zen-ca...roducts_id=1492

Has anyone tried these yet ? any opinions on how they fly ?

Ryan.

Just saw on the other site where Matt Botos was going to try them soon. I have them in my Raptor 50 and they work great.

Matt made a comment about being sure not to add too many shims with these.

Should be interesting.

I've had them on a raptor 90se & 50se, the main reason i got them was to prevent a boom strike, i don't think thats going to happen with the Synergy.

Well i know the boom is lower, but without a bit more damping something is gonna give on mine soon!!

Seriously.. it is.

Standard damping is not adequate at 1950 on 710's

Unless your hovering

It will be interesting in what the two stage dampening provides over the "standard upgraded" dampeners that we are all using..

I had them on my R90se and XeroG600ep and rated them very well for good old stick banging, and the added security of not wiping the 90 tail boom off

I am interested to here if anybody on here has tried them on the Synergy, as they seem to have appeared without anybody mentioning that they have been trying them out

Can I take it that you will be ordering a set then Droid ? or at least realraptors hard dampers ?

I now have a set on order, so it looks like I will be finding out the hard way what they are like

I will let you guys do the testing on this one. I installed 4 hard O rings with one think and one thin shim on either side of the head in my N9 and the thing osilates if you load it to hard. And it osilates BAD at any head speed below about 1700. I run it at about 1900-1950 and at that head speed it is a blast. But you can see the head osilating at times in hard manuvers. Plus it has that to stiff head thing at the end of an auto. So I think I am going to try removing the thin shim to see what happens. If that doesn't change it I will go one soft and one hard to see what that does. But from my prespective this head seems to be sensitive to real hard dampening. Which is odd, as it is basicly a copy of the MA head. And all of the Fury's I have had I had set up stiff as hell and they never did this. So something has got to be different that is causing this head to react the way it is when set up real hard. But it could be just me. We will see how the Infinovations go. If they get real good reports I might give them a shot. Who knows. So get on with the testing guys.

Build it, fly it, crash it. Repeat as often as needed.

Did you try one of each, one hard one soft?

Could call it Variable Damping or VD for short.

Not yet. I am going to remove shims and see if that helps. If it does not I am going to go one hard one soft and see how that does. I will be keeping my eye on the reports about the Infinivations. If they are performing well I might just have to get me some.

"Standard damping is not adequate at 1950 on 710's"

I would disagree. I flew mine for many gallons with the stock o-rings at 1940 with Curtis 710s and it flew great. Then I changed to Ron Lund's hard O-rings and suffered oscillation at the bottom of autos. I now have one hard O-ring in the inner position and one soft O-ring in the outer position and it still flies great, and only has a little oscillation at the bottom of the autos.

The stock o-rings fly fine, and the hard o-rings fly fine, with the auto oscillation issue.

After many years of chasing new stuff with dollars, I am trying to fly with fewer effort and fewer dollars for the same enjoyment.

I tried the hard o-rings because I have them. Does the Synergy need them, no. Is it worth trying them if you already have them, yes.

My opinion only, and I respect Droid immensely for having the concern for building properly to ferret out the issues he brought to light as I had those same issues and more.

The Infinavation dampers, until now, were to change helicopters with rubber donuts to o-rings. The Synergy already is an o-ring design. I would not expect a drastic change with the 2.5 mm cord o-rings in the Infinavation mod over the standard 3.5 mm cord o-rings.

With regard to the comment above that the Synergy is basically a MAS copy, not true. The head block is wider than a Fury or Predator, which is why it is more sensitive to the the hard o-rings. The compression resistance of the o-rings is not the parameter of concern, it is the applied moment to the head block. The head is wider on the Synergy, thus the applied moment is higher for a given o-ring hardness. That is why the Synergy flies fine on the soft o-rings, whereas the Fury and the Predator showed a definite improvement with hard o-rings.

As always John, interesting reading. I will give the hard/soft combo a shot and see what I think. Thanks for the information.

Do you think it would just benefit from more shims on the stock o rings? If the boom was in the same place as a r90 i would have taken it out a long time ago!!

BTW have you tried the hard o ring on the outside??

With hard o-rings, example 90 durometer fury dampeners, remove the "plastic" head axle sleeve. This ELIMINATES the wobble at the end of the auto and oscillations in Hard moneuvers...

I do not know. I am only using one thick shim. After flying with a clipped axle on other helicopters I have a thing about preloading the bearings, so I do not stuff the shims in.

Truthfully, I do not think the shims are all that important. The helicopter responds when the force through the rubber is a certain amount. What is the time difference in milliseconds for that force to be achieved with lots of shims versus not many shims? Not very much difference, I would imagine.

I defy anybody to overload this helicopter even with somewhat soft damping, as mine is with only one shim. Obviously since adding the hard o-rings causes oscillation, the stock o-rings with just the one thick shim are very close to ideal already.

I am guilty of this with hard o-rings, but I already had them. What is the flaw that you are trying to fix over stock? If there is no flaw then the whole process is simply experimentation, not necessity. I will admit that applies to me, but I already had 50 hard o-rings. (I buy in bulk)

One reason this helicopter tracks better than others is the plastic sleeve. Remove the sleeve and you allow the blade spindle to move off of alignment with the head which shows up as more non-pure inputs.

Me and all my friends flyng the synergy with fury 90 duro o-rings without the plastic sleeve from august, and tracks very well, the sleeve have the same function that have the central pin in Raptor and in R90 with infinavation dampeners with tuning kit you must remove the central pin...
