this thing not only flies awesome, its also tough as hell. not a single breakage yet and i really don't treat her well. I like fast flying or going through obstacles and reguarly crash it full speed into things. the 9958 is tough too, but not as much.

I did watch to the end and saw all the high speed crashes. Yes, the V911 is super tough ... I've crashed plenty of times and have never broken anything. Only thing that does happen is the swash plate starts to separate some as discussed earlier, and the tail motor can wiggle out of it's holder some. Just been pushing them back in for now. Key is to not crash.

For sure take things apart 1st, this will give you a better idea where you might need to apply the glue and you will reduce the risk of getting glue in the wrong places... speaking from experience.

Thanks for the tips!

Is this a fully stock heli?

Hard to tell if it is stock, probably is since there's no mention about mods.

Here's a nice video showing the V911 turned loose indoors (V911 flight is the 2nd heli shown, about the 2:59 mark)

Well, the loose swash plate is definitely an issue on my chopper. But the non-working servo action is what's making it unflyable.

It's weird: If I hold the controller in one hand and chopper in the other and watch the chopper as I move the control stick, sometimes straight forward works, sometimes it doesn't. And sometimes straight backward works, sometimes it doesn't. If I turn the control stick in a circle, everything seems to work.

Ugh. I didn't want to have to return this.

Easy mod to get better precision:

The highlighted collar is meant to be situated so that the screw lines up with a hole in the shaft... but the hole is drilled too high and allows the shaft to move up and down when the servos push up and down on the swashplate. I've found it's enough to snug the screw up against the shaft at a lower position even though there is no hole there.

Now you're making me wonder if there's a loose pot in your transmitter.. if circles consistently work that's weird and hard to explain.

My V911 has almost no axial play in the main shaft. If I pull up and down on the main shaft in the axial direction, I can feel just a hair (maybe 0.003") of freeplay.

As a response to you idea in post # 1365.

After looking closely at the collar with the 4 balls, and how it sits inside the inner race of the swap plate bearing, it looks like it would be easier to glue it in place when it's assembled. If you look at the bottom side of the swash plate bearing, you can see the lip of the collar protruding slightly beyond the inner bearing race.

I'm thinking that if you pulled the collar out of the race about 1/2 way, then put a very THIN layer of glue on the inner race diameter, then push the collar back in to fully seat, you would have a nice thin layer of glue around the interface between the collar OD and the race ID. There might be a hair of excess glue that pushes out on the bottom side lip, but if used sparingly it shouldn't get anywhere near the ball bearings in the bearing.

You are basically making the bottom piece (the piece that fits inside the bearing) a little larger, to insure a tighter fit.

The real question is, why is this occuring on the v911? This was an issue with the mSR. E-Flite even includes a "calibration" tool that helps to reseat the swashplate. Kind of a lame solution IMHO.

The Solo Pro never has this problem. So why does the v911 swashplate, which is a clone of the Solo Pro, subjected to this problem? Odd.

I am going to compliment the person doing the recording instead. Well done anticipating and following your helicopter without too much camera shake or unnecessary operator induced motion.

Usually, you can take out this play by pushing the main gear up and collar down. So basically push them towards each other. But leave a tiny, tiny, tiny bit of play so that the shaft can rotate freely. Like the poster above said. 0.003mm of play. LOL

its quite hard to focus on this tiny thing when it zips through the air.

Wow, nice photos Mulder! Did you have Skully near-bye taking the candid shots?
What camera did you use, and what focal setting? nice DOF... didn't know you could snap those in action! I only have a Fuji HS10 Digicam, I doubt if it's as capable as your camera.

Exactly. My 2 had much too much play when the screw was seated in its intended hole: about 3mm

The loose swashplate isn't a problem on mine. 40 flights and as many crashes and I only had to snug it up once. Even then it wasn't all the way separated.
