Hey Guys,

Ain't been able to get out with the R90 this week!! the weather here in the UK has been......well.........for want of a better phrase!....CRAP!!!!!

Those dampers look very interesting, design looks very similiar to the CX Dampers with the solid dampers for 3D and the O ring dampers for the hover damping.

Jeff, how are you finding these dampers compared to the CX and red TT dampers? I've fitted the Red TT dampers in my QUK head and the heli oscillates in the hover, the heli is brand spanking and has only had 2 tanks through it so far, i'm hoping that it goes away once the engnes gets broken in and the head speed increases.

So far i'm liking the feel the R90 with the red dampers, even with the low head speed it's twitchy!! It's gona be a wicked beast once that head speed gets up there!!

Just out of interest, are those dampers available yet and who is producing them?

Cheers!

Well. I have tried them all.

The Red ones need to be well lubed and are ok, and allow the spindle to auto center left to right. sounds like you need to really grease yours up, and maybe pull out a shim.

I found the cx dampeners last year to be real nice for the first few flights, but then they changed as they wore in a little.

These new ones shown here (made by infinavation.com) have been proving to be a real nice, do everything well, dampener. They center left to right, they dont have any wabble at low head speeds because of the design and placement of the o rings, even in a drawn out auto that slow the blades way down they dont wabble. At rpm, They are real crisp feeling when called upon, and the new orange ones are a self lubercating material so the spindle stays tight, yet free. I have about 4-5 cases on these dampeners and they are working real well. I believe that several more dealers are currently being added. and they are available now thru the website.

Thanks Jeff,

Sound advice! If memory serves i added one shim either side when installing, will check when i get back in from work as it could have been two shims

Dampers were greased up well when installed but if the problem persists then i'll re-grease them when i remove a shim.

Sounds like it could be a shim problem as the dampers were greased well.

What shims are you guys running with the Red's?

Cheers!

Hmm i got an e-mail from Carbonextreme that the CX dampers normally last for one season with regular flying.

Now what should i do,order a new set of CX dampers,try the red dampers inside out,or wait till the new ones mentioned before are coming out???

Hmmmm..!!

I checked last nite and i have the standard spacer ring and one shim on each side!! So judging by Steven's setup my setup should not have no wobble

Me thinks a regrease may be in order!
Strange because they were well greased!!

Cheers!

It maybe that they have not been lubed up enough or the installation has rubbed off the grease as the red dampers were a Tw@t to get into the hub!

Hey Raptor30:

I normally try to replace my dampers pretty regularly anyway and usually replace every season, normally during the winter months when a few of the machines have been put to one side.

Unsure of how the larger dampers of the R90 are going to were but in my other machines like the fury or the mille which have O ring dampers i replace them every season.

Going to try these reds for a while and see how they feel while the enigne is in it's break in and maybe have a regrease of them if the wobble don't improve but i'm considering a set of the CX dampers.

Cheers!

Hey,

I was out yesterday evening with the R90, had a good evenings flying! And it's sorted!

Well, sort of!

The first couple of tanks were same as before with the model having this wobble but over the next couple of tanks the wobble practically vanished.

The head is doing roughly 1540 with the tacho.

I think it's just going to get better and better!....I hope!

Only thing now is i have the gremlins in the Auto hub! Little buggers!

Cheers!

There's really no reason you "have" to run an abnormally slow head speed during break-in. You are actually forcing the motor to work harder. Crank it up, and be done with it.

I got a set of these new dampners from East Coast Extreme Helis a few weeks ago and have put about 30 flights on them so far and I really like the way they feel. I was running the Red dampners turned inside out wit 1 thick and 2 thin shims prior to using these and they have made my cyclic much more crisp but still no wobble at lower head speeds.

Try it....you will like it .

Hey Led,

Thanks for that, will look into a set of either CX Dampers or those East Coast dampers later on, i like the red's at the moment! they seem to have got better as the machine has run in.

I'm liking the R90 aswell, i have been HAVING so much fun with it trying new manouvers with it and basically being released from the heavy repair bills of my Fury, you may note having is highlighted!!

Well having is very appropriate, i was having so much fun with it at the weekend i had a brain fart in a manouver and that was that!! Cheque please!!

Anyhow's, that's what i bought it for and it'll be flying again very shortly!!

A sponsor of Raptor parts and SAB blades would prove very usefull at this point!!

Cheers!

Hi RotorHead
you can get the red dampeners in the UK, I think Real raptors now have them in stock, I spoke to them last week, and they said they would be in this week

If you mean the TT reds then i already use these, but if you mean the East Coast red dampers then i'll look into some of them.

Well, I've had the Infinivation dampers on the EVOs now for almost two months:

No bent spindles in flight since the install!

Even at low head speed on an auto - no wobble. (had to get used to that - I used to judge my head speed by the wobble)

I don't have to lube them.

Stiff and crisp on the high speed manuevers, smooth as glass in a hover. ( I think its because they seat against the rubber when you put them in the head, instead of against the polymer "red stuff")

No pitching in FFF

Less expensive! $$$

Over 70 flights, no obvious wear. (The "red stuff" seems REALLY tough!). Had one dumb-thumb crash - no damage to the dampers (lost a set of v-blades, a spindle, and a mast though )

Only thing I forgot to find out is whether I can get "O" rings if these wear out. They seem to be Viton. (Of course, at this price, I may just slap a whole new damper set in if the O-rings ever wear out)

Now, I'm NOT a heavy-duty stick banger (not on purpose, anyway ), but for me, these have held up MUCH better than anything I've used so far. Not trying to foist my opinion, not trying to say they're better for YOU - just thought I'd give my observations so far.

Guess what? I just saved a ton of money on my Auto(rotation) insurance!
