WL Toys V911 Control Rods

Hi All,

Decided to actually read the manual that came with my v911, and noticed that on page 4, it indicates that the servo arms have two holes (inner and outer) where the control rods attach. The outer holes are labeled "Nimble Flight", and the inner holes are labeled "Stable Flight". The default appears to be "Nimble Flight". Has anyone moved the rods to the inner holes, and was it worth it?

There's also the adjustable swash plate and the two flight modes on the transmitter. The transmitter always starts in mode 1 (stable), the button on the top left switches modes.

I have everything set for nimble flight and I love it, nose dives are a ton of fun. It all depends on what kind of flying you want to do. Indoor flight is a little tough for me but I'm still a newbie.

Leave it on the outer servo arms. Use low rates on the TX for indoor flight in a small area. I found that the inner holes made it too sluggish to respond and actually made it more likely for me to crash it as I couldn't pull out of trouble.

The top left "Mode" button changes the servo throw. With the heli sitting on the bench, push the aileron and pitch sticks (the two that move the servo arms) and note the arm throw and note the graphic representation on the LCD. In one mode, you get about half the throw than the other, full throw. The LCD provides a quick way to see if you are in full throw mode - move the sticks and see how far the bars fill in.

Call it Mode 1 or 2 (my TX always reads Mode 1) or junior and advanced or high or low rate... or whatever else Chinglish manuals may contain. One position reduces the servo throws to about half.

I tried the inner servo arm hole position with the intention of setting the copter to be an indoor mostly setup. I have another V911 somewhere in the post from China - intended to keep that in outer servo arm hole for outdoor flight. But: the inner hole position slows down pitch and aileron response but does not affect rudder. When switched to high rate the rudder was far too sensitive compared to the servo controls. So: put the control rods back into the outer holes.

It would be nice to have a TX with full throw controls for each of the heli functions... but that would be beyond the V911 price tag... and also the V922, it seems.

The tx for the Double Horse 9116 is compatible with the WL Toys line of products, especially the V911. You have to reverse the tx's elevator channel though. It's very easy and you can adjust throws etc to better control your V911. The tx is available for $7 at HobbyPartz.com, http://www.hobbypartz.com/67p-9116-26.html
DH QC isn't all that great but I didn't have any problem getting a 2nd one from HP when the rudder trims on the first one I got didn't work.

Just got mine yesterday. Do we need both ail & ele (page 10 & 11) to be horizontally level and the both servo at 90 deg (at least) at neutral position?.....

I just have my elevator REV. Try the controls on the deck after binding and you should be able to tell if the aileron needs reversing but I don't think it does.

Yeah! Just got my replacement bird today. Good thing since the tail motor in my original is having a bad day.

For those getting the double Horse 9116 TX if you have sticks that seem not to work, it's not hard to fix them. Just look for bad solder joints. Bummer than you have to fix it at all but still not a big deal.

No. The v911 doesn't actually sit level when set up properly. It leans a bit.

Start out with your servos at 90 degrees, and give it a fly. Correct drift by turning the rods to lengthen or shorten them. Once set up, it should hover pretty stable with no drift without needing trim.

Rainy Saturday so had another fiddle with the V911 trim.

The swash plate has two sets of arms - long and short. My copter came with the links set on the outer (longer) arms. According to the Blade 120 instructions (downloaded from their site), which the V911 seems to mimic, the longer arms are for a more "aggressive" setup. Since it's windy and wet outdoors, I set the links to the shorter arms and then noticed that the servos do not have equal throw about geometric centre... so reset the arms to the next notch down and spent time re-trimming the rod lengths.

Very nice! Indoor hands off hovering for very long periods (if I had turned off the ceiling fan, it may have lasted for minutes.. LAC (Like A Challenge) - fly under a ceiling fan.).

If anyone is learning to fly a V911 in tight spaces, I recommend putting the rotor head links onto the inner / shorter swash plate arms and fly on the lower sensitivity TX setting - very nice flying in the living room. (However: I do not recommend trying the inner servo arm holes... that needs someway to reduce the tail motor rudder reaction to balance the with the reduced servo throw.)

An aside: periodic applications of sewing machine oil to all the moving parts has reduced the noise and is making the V911 a sweeter machine. Drops of oil on the tail motor shaft have finally quietened it and brought it's running temperature down to sensible levels. Seems the motor shafts were tight on my V911 causing noise and frictional heat.
