The leaning is a product of the helis size and weight and the vibration is common though not really normal. You could have a flybar or blades that arent perfectly balanced. If its a slight vibration then I wouldnt worry but eventually it could start wobbling in flight. When you see that... you need to swap out blades or flybars to correct the problem. I had a flybar that mysteriously wasn't balanced anymore so I shaved a little meat off the opposite side to help even it out again... worked like a charm.

Very nice! I'm going to search back through this monster thread for more info (already read every page, just need to parse the LED/resistor stuff) - I know that I read over a lot from those electrical engineer-types that made my brain sore, but seeing that LED pic makes me think that it's worth it

Check it out! He says it's tight but that can be easily managed.
Ah ha!!! Well, he says that it's tight. I don't know how easily that will be managed though. Why is it tight? Is how the flybar fits into the head tight? Fix that with some filing. Is the bolt that goes through that tight? Maybe fix that by carefully increasing the hole size with a drill bit? Are the swashballs tight? Not sure what to do there other than try using the Helios links and hope they're not too loose for the blade linkage arms.

Thanks for the link. I missed that when I unsubscribed from the Helios 100 thread. No FlySky compatbility == no purchase for me.

D'oh. Thanks!!!

The lean is normal. As long as you can fly it okay with the vibration, you're probably fine though it might be to your benefit to try all of the above suggestions. Vibrations usually get worse over time as the rotating parts will start to wear unevenly.

I've received today my "Yellow" V911 from banggood. PCB ver. 24/06/2012 JLDZ-101A
It had some minor issues:
- banggood sticker ( i hate sticker)
- flybar slightly deformed due a lack in the packaging, probably the parcel got a knock.
- some rusty screw and arms
- I had to secure some small plastic piece of the tail boom and the wire of tail motor where touching the servo arm. I used som matte black nail polish, cheaper than glue and easier to apply/remove.

All in all i like how it perform, it is my third v911 and all fly different. This is very stable and it does more precise tight turn.
It bind very easy with the stock TX, no need to rebind after battery swap.

I agree. That sticker is really annoying--especially when trying to remove it!

hmmm.....maybe I was mistaking dislike for different? I'll put them back on and give it another whirl.

Pretty sure the Helios has a 300maAh 3.7v batteries. Significantly larger. Plus the Helios looks hot.


EDIT: Just went back ad looked. It's a 180mAh. IDK why I thought I read 300 somewhere.

I mostly fly the paddled v911s at a park with plenty of room for them to run. Also even more fun just windsurfing in front of me. Full disclosure: even though perfectly balanced, I hated flying the paddles indoors even with d/r pretty low on my 9x. No room to recover even slight aerobatics...

@JayDoc : how long is your paddled flybar? I'll measure mine and post that info later.

interesting. Someone else mentioned liking paddles indoors. To each their own. Maybe I don't like them indoors but will outdoors. I never tried the paddles outdoors, but will. Too hot and too many mesquitos (West Nile virus) right now. However I would not like two flight profiles, indoor/outdoor, so I'll have to pick one.

I'll have to find an exact measurement when I get home, but I cut the stock bar right at the point where it starts to 'bell'.

Once the bar ends are sanded, I push to the stopping point of the large hole in the MSR paddles to check fit. Then pull out, smear w/a toothpick of CA, carefully watch for neutral pitch as I jam them back in. Balance on a pin, and add a touch of CA to the outside holes until perfectly level. I do add the tiny screws, but I don't think it matters after the CA...

I know my first paddle attempt was an outdoor only flyer! There has been some West Nile reports around here too. But I rarely get bitten by mosquitoes. The only times I ever do and its still rare, is when there are no animals or people anywhere near me, if there are others around they get bit and I don't.

Thanks. I'd be curious because I think a longer flybar makes it more stable (at least that's what happens with the MCX series of coaxial helis...) and I'd expect that the folks who make their own around here will have different results depending on how long they make theirs.

I also cut mine off at the point where it starts to bell but I didn't sand mine before shoving it into the paddle (noob mistake--my first paddle)

Short flybar does make it less stable, more twitchy, and tippy in the sense that you can get the heli in an unrecoverable attitude (if short enough). If you have enough spares you can make several of different lengths and use according to your mood. With long flybars you can experiment with adding little paper sleeves along side the paddles, my theory is that will add stability w/o adding much weight, and perhaps delay the reaction of the flybar slightly. Anyway, it's easy enough to do, and reversible if you don't like it.
