RC beginner
most battery damage occurs from too fast charging. not overdischarge which is the popular theory. truth is the slower you charge the longer they last. check voltage with a meter and make sure they get up to 4.0-4.2v though. if motors are not running hot or no obvious mechanical issues then the problem is probably your battery. i added a better connector to mine so lower cost ($1) cells can be used and i can swap out with my s107s.

The "WLToys-Heli-V911-B" is the part number for the V911 at that store. If you look at the title it says:

WL V911 Micro Helicopter (Black & Orange) WLToys-Heli-V911-B
What is misleading is that there is no comma between the product name and part number. With all the changes, what is coming off the factory floor right now almost could be called the B model

Again this question.

I got a 0.8 mm (outer diameter) | 0.05 mm˛ cable, but this is too thick.

Which gauge size is the cable for the tail rotor?

I followed the thread religously after I oredered my 911 but lost interest after HK me around for so long. Now I have finally got it, it has multiple problems.
I cannot keep it airborn for more than 60 seconds as the batteries do not seem to charge or hold a charge. Not sure how to figure out what is wrong, charger or battery or even Heli.
TBE but it is hard to tell without getting flight time up.
My Heli on the last short flight started to lurch in the air and make a grinding noise.
What to do, where to start, is there a blog or sticky somewhere I can look at?
Any help greatly appreciated, I read everyones posts early on and thought I was buying a great Heli, I think it may still be but it is so frustrating. The Co Ax I bought at the same time was great to learn on and got repaired several times over the 2 days I flew it but I really want to get the 911 flying.
Is there a better battery charger, my skid does not come off so cannot do the skid change.
Check your battery contacts on both the charger as well as the heli. Take small pin and pry the contancts out a little so there's more tension on the leaf springs on both the charger and heli. Clean the battery contacts with rubbing alcohol (on heli, charger, and battery). You are charging with the USB charger and not the onboard charger in the transmitter right?

I don't like the idea at all.

Max out forward trim to increase forward speed.

Another idea is to add 1 to 2 grams of additional weight. That'll force you to increase throttle, which will increase forward speed. You'll want a drug dealers' scale if you don't already have one.

If it looks like this, you need a new motor.

On my Xieda 9958, the toilet bowl effect is easily seen upon lift off.

It's become almost a personal challenge to me, I would love to have Infidels 9958 for a while just to prove I could get the TBE out of it

Hi everybody,
I'm pretty new in the RC heli world so ...
I just received my v911 yesterday .
I noticed different things that made me wondering if everything is alright.

1) I don't have the 2nd screw on my PCB (the one on the pic), is it normal?

2) I find my v911 drifting to the left a lot, I can manage it with the "software trim" but I think it need A LOT of trimming. How can I fix that the "hardware" way? I try to unscrewed the black part on the servo's arm but after reflexion I don't think it is the good way to do it...

3) Is it normal that my V911 "whistle" like when you play a saw with a bow ???

Thank you very much

For mechanical trimming search my posts, couple of pages ago.
I never played saw with a bow, LOL !

Yes you can there are a couple of places that sell them. You will pay more for them then if you ordered from China/Hong Kong, but delivery will be faster

The one place that I have book marked is
