E-Flight Blade mSR Wobble

This is my mSR showing how the control arms vibrate at slow speed and translate into a larger vibration during high speed rotation.

I was never able to fully stop the wobble. After posting the video, I picked up on what swiftay18 commented about and then offset the screws. However, the only thing real fix-action was to remove the MH grips. I liked the look of the metal parts but the weight and imbalance just was not worth it.

Alright, I've removed all the MH parts and the birds flies like normal again. I trouble shot the issue part-by-part and it's definitely the blade grips.

@streetspec1, you are correct about the hole diameter and I had already drilled it out the holes a little just to get the feathering spindle to enter. I've also replaced the main shaft but it's still shaking just like in this video.

I'm not sure how much it affects flying but it was there before the Microheli parts. However, since installing the new parts, the heli has developed TBE pretty bad.

Your main shaft is bent.

I have two MSR's and my backup MSR was doing the same. It disappeared after replacing the swash plate.

My Dad's MSR had the wobbles aswell to the point where it was unflyable. It would life for a few seconds with no controll over it and then crashes. It turns outh the ribs holding the the flybar/blades/swashplate togetther were not all the same since we replaced they with ramdom ones that we had left over. We replaced all the ribs with the propers sized ribs and it's flyable now.

To everyone sugesting its the inner shaft might be bent. It can't be. Its carbon Fiber. if it bends it will Break.

@raptormstr I think your main shaft is also bent.

Booooooooring

I have watched a few vids describing the exact same problem...my conclusion is it has have something to do with the main shaft....E-flite claims this carbon fiber version shaft will not bend,I disagree...Yes maybe it doesn't bend to the naked eye...I'd bet money if the shaft is evrso slightly of by even a half a millimeter,you'll get that problem....I'm trying to conquer a shake on mSR at the moment..Iknow u posted this a while ago,but what ended up being the problem...Thx for posting this.

that sucks, because mine never wobbles like that, unless after a good hit, then i push swash bearing back in and it's fine. as long as it flies good, doesn't matter. Happy flying! : )

@Wiiviewsowner no problem, but curious... did it work?

[whatsdare]

@Wiiviewsowner the swash can do that to the heli, all you need to do with a stock swash like this is, push the outer bearing housing firmly into the plastic swash plate, (all around.) usually fixes this. (until next crash.)
