Yes just sand it down and make sure you balance it.....

Or just "START HERE" This should be 101 class for V911

Wow, I love flying this new bird! Was able to hover almost right away. Throttle and rudder on the same stick will take some getting used to but out of the box I flew twice through charges on the two lipos without a crash (ok, a couple of abrupt drops from low altitude onto the rug...). It's very fast, makes my 12'x22' living room seem really small.

What's in the BG BNF box?

After reading the entire GW9958 thread (478 pages), it became apparent that the verdict is in and the micro FP heli of choice is the v911. Seeing that Banggood has the BNF for less than $20 shipped, I figured that it would be a crime to not buy three of them (all three colors), so I did just that. I also see that the new version sports a new connector - unfortunately I assumed that they went with the pico/mSR/nanoCPx/9958/etc eflight style battery connector (which would have been the logical choice - I've got a buttload of them), but I was dismayed to discover after searching this thread that the new connector is actually the larger mCPX one - D'oh!

So here's my question:
What is included in the Bangood BNF v911? Charger? Batteries? Spare blades? (Obviously there's no Tx.)
Also, what's the best way to modify this new connector version to handle the pico connector?

Thanks in advance,
Jeff Roberson

Nuthin. Just the helicopter. Think of it as two helicopters, and one of every spare part.

Well my BNF red and white V911 arrived from banggood yesterday after sitting at the post office since 2/8. Ordered on 1/20 and arrived on 2/8 to NC. Not bad 15 working days exactly as advertised. I think the red/white has more punch than my H911 and also was true and trimmed right out of the styrofoam box. Unlike the H911 which i had to do quite a bit of mechanical trimming to out of the box. Also got some screw sets for just incase (and because i had lost the flybar screw on the H911 and been using a bread twisttie), heads, and flybars to start doing some paddle mods. Sweet thing about that Xtreme MSR set is it comes with 2 sets of paddles so you can do 2 flybars with one order.

Some of you seasoned guys might not know this (because you haven't ordered a new V911 in a while) but I had a Lightning bird that i sent back because the motor burned out within 10 flights. But it had what i assume was the old style tail motor with the same diameter shaft all the way into the can. But both the H911 and my new BNF have a stepped tail motor shaft. So you can only seat the tail rotor to the step and it can't go all the way to the can. Pretty sweet. Now when the tail burns out i wonder if you will get the old style motor or if they are only making the new ones now....???

Tail Motor

I have three v911's. My original red/wht one and a Y911 and most recently, a W911. The W911 is by far the most quiet! However, after about 5 flights, no crashes,the tail motor died. I make sure to bring the heli in before the motor has a chance to get too warm. I also have the motors below the tail boom with the tail rotor reverse to help keep it cool. Anyway, just a FYI.

I've read that running the motors in reverse will shorten their life since the tiny finger brushes are oriented for spinning in 1 direction. You may have more air going over the motor, but may also be making the motor run hotter by running it in reverse. I really don't know for sure one way or the other, but something to consider.

The black/orange V911 I got a little while after Christmas didn't come with the stepped motor shaft. I have a BNF on the way, though. Sounds like a nice little improvement!

I placed an order on 1/24 and I'm also in NC. Maybe it will arrive today! *fingers crossed*

Why did the PO hold your package for so long?

Yeah, something to think about. I have all three of my heli's set up this way. The motors are much cooler after flying then before the mod. So far only one has died so quickly. Maybe someone else will chime in.

While I haven't seen the 911's motor, I've taken a couple of failed 107 motors apart. While the brushes were partially destroyed, the cap that holds them is completely symmetrical. I saw nothing that suggested the motors are oriented for spinning in a certain direction. I don't plan on running them backwards, so I'm only discussing it out of curiosity but I'd love to see some evidence that they are "orientated" or not.

As I mentioned in previous posts, my H911 made her maiden flight last night. I understand the need for letting the motors cool between sessions. Given that, how long are other owners finding they last? Should I have a few on hand?

I have dissected the 7mmx20mm motors on my X4 trying to repair them and the brushes are definitely oriented for 1-way travel. I'll try to take a pic later tonight, but basically spinning in the correct direction has the armature pushing out toward the ends of the finger brushes while spinning backwards has the armature wanting to bind them up. Imagine a spinning log and putting your hand against it. In 1 direction your fingers will just flow over the log; in the other direction your fingers tend to want to bind up on themselves.

I didn't have time to go get it. My mailman is lazy and if it doesn't fit in the box he sits there and takes the time to fill out the "your package is at the PO" slip instead of walking his lazy to the front porch.

I feel like Chevy Chase in funny farm

Does anyone have a reliable source for the Bravo SX motor? I've looked and they are sold out most places. Myrcmart and ebay have some but I don't have experience with either one of the sellers.

I wrote my post before coffee. Now that I'm fully awake, I realize that you are correct. The brushes lay against the commutator which spins toward the ends of the "fingers". All things being equal, the motor would probably work just as spinning well in either direction but the impact of a crash while spinning would have greater potential to cause damage to the brushes, like buckling the fingers, if it were spinning the other way.

Have you ever achieved a successful repair? I've tries a couple of times but fabricating those tiny brushes out of what I had lying around has proven extremely difficult. I figure thought, with a few more motors replaced on my 3ch, I'd have at least a couple of good brushes in the broken parts bin.
