Could you clear up something for me. On the Xtreme skids, can the battery cage be removed? I thought I see a screw holding it together to the frame. It suggest you can unscrew to remove the battery cage from the skids. Thanks.

BTW, I got the white one also. Is your RX the blue, rev.02 version like mine is? Seems the black heli and spare RX are coming as rev.04.
Thanks, did you get the White-Red or the White-Blue? I not seen any pictures of the Blue yet, it's more striking/better looking in real life. Kudos to the Art/Design team @ WL Toys!

The RX is Green rev.04 on both my V911's, your White has the Blue rev.02 RX? huh.... I wonder why? If you have "both" are there operational differences between the RXs?

The Extreme Skids' battery box is indeed held to the skid by a top mounted screw, the box looks easily rotatable. The copper battery contacts are nice too.
It would be interesting to Mod it for the V911, but I've got a bag full of stock batteries to use up.... and my "ver.2 Velcro battery strap" works great for using my NE batteries in the V911 battery box.

Servo Problems

My 911 has a strange servo problem, without the motor running they work smooth, however with the motor going they are very twitchy moving in steps and hesitating.

This makes for challenging flying

any ideas???

I am curious how the white/blue version looks as well. Yes, my red/white version has the blue rev.02 board. We're building a v911 from parts and that will have the rev.04 board on it. I will see if they fly any different and report back when I can discern any differences between them.

@Tilly,
Did you always have this problem? Or did it started recently?

I had the same problem, I was looking for replacements for my mSR, it is just a matter of keep trying till you find the size you need

I think you would also find that different helis have different sizes needed

As a very untidy fix you could cut a small square from an elastic band, put a pin hole in the centre and that will slip over the rod, this won't win any beauty contests but it would do till you find the size of cable you need

My v911 doesn't need the o-ring. The mSR and NineEagles need the grommets because the plastic used in their canopy is optimized for weight. So it's very, very thin and flimsy. The grommets helps to 1. secure the canopy to the frame, and 2. to prevent micro cracks around the hole in the thin plastic.

On the v911, we don't have these issues. The plastic used is solid and holds on the frame perfectly secure. Why add additional hassle of putting o-rings. That a flawed design that E-Flite abandoned when they revise the mCX and created the mCX2.

It started a week or so back, also the gyro is acting like the gain is set too high. I have a new board on order shipped out of HK the 17th.

As mentioned earlier by the OP, a website by the name of taobao.com also sells the V911. I did some digging and they actually have a seller with pictures of the blue version of this heli. Link: http://item.taobao.com/item.htm?id=1..._4z6_773219696

Thanks for that helpful 1st post @FrugalisFlyer. Welcome to the board.

@Tilly:
It's possible one of the motor is going bad, drawing too much current for the RX to properly drive the servos.

Of the two motors, I would suspect the tail first. Try throttling up and pressing the rudder full LEFT. This should prevent the tail motor from running. Move the AIL/EVE around and see if the servo is still glitchy. If it is, then perhaps the main motor is the problem. Proceed to the next part for further testing...

Part2: Checking to see if Main Motor is the culprit
If you have an extra motor, you can try swapping out the motor. Or you can try to desolder the motor wire entirely. Then resume testing by throttling up and moving the servo around. See if the glitch goes away.

a few people asked for it so I exported my ER9X model settings for the v911.

either download and extract the attached zip file or get it straight from this link

the zip contains both model configs for v911 and 9958, you can import them individually.

v911 config summary:
* throttle safety switch - (Thr. cut switch)
* lift off assistant: mixer to prevent sliing left upon take off
* throttle activated timer
* 50% expo on RUD, AIL and ELE
* 3 preconfigured rates (RUD, AIL and ELE) on the 3-way switch (L-M-H)
* poti controls rates 0-100% (RUD, AIL and ELE) - (right poti)

Nicely done @Mulder_

I'll take a look at it when I get a chance. Thanks for sharing.

Edit to add:
I am trying to program in for those that did the BS170 tranistor mod for their backlight panel, the ability to have the backlight wake during stick movements. And goes to sleep after a set time once no stick movement is detected. I saw the example PatMackezie posted on the er9x thread. But something is incorrect at the moment.

True, the V911 really doesn't need the O-rings to keep the canopy on, but I've found that without them the canopy vibrates and just adds to the noise the V911 produces.

Thanks Daryoon,

I have motors coming also in the pack of spares I bought, just a thought but flight times are not affected at all....Off to check the tail motor now
