whats up with these dampers?

[eightythree]

seven 3D flights and these things are toast.. am i pushing this heli to hard or is this a complete flaw? they are completely twisted from the force of the blades and im getting vibrations. you can actually see how the force pushed the bushings to the side.

is this normal? are the red dampers any better for wear and tear? 7 flights for replacement is just ridiculous, i dont want to maintain this often.. if it just kept up as good as it flies! :arggg:

[nuttcaze]

I have the exact same problem. I'm gonna try the red ones, I heard they're suppose to be stiffer

[nuttcaze]

oh, 1 other constant problem I have, the tail keeps getting bent to one side, no matter how tight I tighten the tail, it still ends up cocked to one side, I'm starting to look at other helis for 3D, the ES600 doesn't seem up to the task for hard 3D, I'm not pushing the heli that hard so I can only imagine the problems I'm gonna have when I get really good at 3D

well i cant say im a great 3D flier, but this heli can 3D pretty well. im not really having much problems, only this damper thing.. i dont know why they didnt design the headblock to be closer to the grips... i was thinking of trying to find some sort of spacer and cut it down to make things more symmetrical rather than using the smaller diameter spacer.

Outrage rc is going to be releasing a 550 heli running on 6s 5000 packs. check out the video on helidirect's page. the pilot is hamering on the thing piroing the whole time! this may replace my esmart for a good 6s flier!

I have not have a problem yet with the stock dampeners and the red ones too. I lubed these with silicon grease(I got it from a dive shop) along with the feathering shaft. Also pay attention on how you reassemble the head after lubing. I have ordered the swift 620 dampeners just to see if they will work.

damyxz- dont you use an 11tooth pinion? where does that put your headspeed?

im flying it with 100 flat in idle up wit +/-12 degrees. im sure the headspeed is around 2200 rpm. maybe this is the cause. i was hammering it around doing a lot of tic tocs, sudden pitch changes, and large rainbows..

if i look at the heli from the top i can actually see how bad they have gotten twisted. the spindle is not at 90 degrees anymore!

before i start messin around with dampers.. do trex600 fit at all? ive got an extra set of extreme k&b dampers. if they have to be shaved down i dont mind at all.

[damyxz]

Yes I flew with 11T pinion, but I changed it to a 10T(I like the handling better still gets 2200RPM on 100%) and I get more flight time out of it. I also experienced the torquing of the shaft on 11T a little bit. That's why I'm trying out the swift 620 dampeners when it comes in. The trex 600 dampeners will not fit because the feathering shaft of the trex is larger in diameter than the E-smart. I have both and I have tried swapping feathering shafts...won't work. As for the cockeyed tailboom, I solved that problem by using the aluminum threaded inserts I got from stock main shaft bearing blocks from a trex 600 and some 3mm hex pan head bolts I found at a local ace hardware store. I set the boom block where it will mesh the tail drive gear and the main gear perfectly while maintaining boom alignment. Tighten the boom block bolts so it will not move. Also make sure the boom supports have the same length. I found a spray on dry lube from a gun shop and I use it on the main gear to reduce a lot of friction.

please report back when the swift dampers come in. i dont want to always change dampers out...

where did you find your 11 tooth pinion?

[damyxz]

I have posted the site where I got the pinion somewhere around here...I forgot the exact name of the site. The pinion I used is a 32 pitch 10T/11T 5mm bore pinion(same as a .8 module) I got it from an RC truck site.

[damyxz]

It's a no go on the swift dampeners....too short, unless you have another one that you can cut to length and add on to it.

[nuttcaze]

One thing I recently noticed is my semi-metal kit which uses the larger feathering shaft doesn't have the same damper issues that my plastic kit has, which uses the smaller feathering shaft. I'm gonna look into getting new bearings and another larger feathering shaft and see if the problems stops. Just had to order 4 sets of dampers. Need 2 and want 2 on hand.

Does the larger O.D. spindle require the larger bearings. I figure it does, but while I am oredering parts, I want to make sure I pick up everything I need. Is it true that all the parts needed to run 550 blades use an "a" after the original part number.

[damyxz]

According to an e-sky rep I talked to, all parts with an "a" designation after the part # sre for use with 550-600mm blades.

[Design Engnr]

Thanks for the confirmation. I am actually waiting on a response from Rare Bear. He is selling his kit and is looking up shipping cost right now. Hopefully I will have my heli by next week.
