Thanks,
I'll go fly my new Syma S110G while the batteries recharge for the V911. I've printed out the directions for trimming... we will see if I can tame this beast.

Ken, first I'd try and make sure you have it set for the lower of the two rates on the transmitter. This is hard to tell, but it's the top left silver button next to the antenna (they call it the rudder conversion changing button). You can tell you're in the lower rates when the rudder indicator on the transmitter LCD (they call it the diversion tips) only shows 3 bars versus the higher rate of 4 bars. It's a subtle difference, but it'll let you know.

Next, I'd take off from your hand. I find that easier at first when learning to fly a new helicopter. Just give it some throttle until it feels like it'll gently lift away and let it go. Then I'd first try and trim the rudder so that the helicopter doesn't spin. Then I'd trim the elevator to keep it from going backwards. Finally I'd trim the aileron to keep it going from side to side. Don't be afraid to even fly it for 5 seconds and then see what direction it's moving the tail in and trim in the opposite direction, then try again.

This may sound a little basic, if so I apologize. I'd also check that all the head parts of the copter are loose enough to move freely and all the linkages are still connected. Good luck.

Ken,

Do this. Your goal is to trim rudder FIRST. If your heli nose turn CCW before take off, shut down throttle and then click right rudder trim button couple times. Increase throttle again to check heli nose direction. Repeat above if necessary.

Emphasis on putting throttle trim all the way down before binding or youre in for a surprise. Mine flew full throttle from the livingroom to the kitchen, hitting my wife haha.
What's your setup like on your turnigy 9x, would you mind sharing with me? Thanks.

Thanks for your suggestions and no, I'm to ignorant in the ways of 4-channel to be insulted. I appreciated your tips and hopefully I can get the hang of this. My main fear is that I'm trying to learn to fly a crippled/defective bird.
I was finally able to keep it in the air for more then 5 seconds with your tips (hand take off). I think I've been able to trim the rudder OK, I can usually just sit it on a hard surface, give it some throttle and see if it spins right or left and make adjustments there. Some times I got the shuttering effect the last couple of attempts, not. I shot some video. The strange thing (at least to me) is that when viewing the Heli head on, it might be hovering sort of stable for a few seconds but the entire body of the Heli is leaning to the right!!! Is that normal. It's been that way since the 1st flight. I've only had coaxials before so I thought maybe this is normal but now I'm starting to question this. If you see my video later, check it out when you are viewing it head on.
Again, thanks

cpuken, since you said you're not easily insulted, I'm going to chime in. I find that using thumb and fore-finger to move the sticks (vs using thumb only) makes a big difference in maintaining a hover, and making minute maneuvers.

Ken, yeah, it's normal for the heli to look like it's leaning in the air. I don't quite understand why manufacturer's don't offset their bodies so it at least looks like it doesn't lean in the air, even if then it'd look silly on the ground.

I recommend reading the Solo Pro faq, the solo pro and the v911 are similar enough that a lot of the technical details are the same, and this faq is very well put together.

Ken's V911 Training Video - Episode1


OK, this was the most air time I've yet managed. It was relatively stable compared to previous flight attempts but either it or me needs more work.
For the most part I'm only adjusting the throttle until the very end of the video when I adjust the rudder. This Flight did not display the frequent shuttering I've been experiencing in prior flight attempts. Feedback and suggestions welcome.
Ken

It appears that you have some TBE (Toilet Bowl Effect) going on. There are different causes and different ways to solve. The best advice I can give you is to make sure your flybar is freely moving, which may entail taking it off (edited to add and putting it back on again, trying to make sure that it moves freely. Or just loosening the screw that holds it a tiny bit.

I'm sure others have some better advice. You may want to read these pages and see if any of this helps:

Ah, so the batteries stick out the back on these? It looks like it's takin' a poop. I prefer the forward mount batteries like in the sp but I guess this kind of mount enables better piros.

Maybe email Ringo-MyRCMart regarding the V911 parts to clarify?

sgnelson,
Thanks for the tips, I'll check that out for sure.

Only getting about 3 minutes flight time with each battery


I'm finally able to keep the bad boy in the air now... just trying to hoover, even with the TBE that i can hopefully sort out soon. For now I'm just happy to keep it airborne.
These are some quick flights because I'm getting about 3 minutes off each battery before full throttle won't even keep it off the floor. Heck, my Syma S110G can double that flight time. Since I have two batteries it's not a total lost but 3 min flights make it a little more difficult to trouble shoot the other crap I'm dealing with.

I think I'll quit for the night, be satisfied with my minor victory (keeping it airborne for 3 minutes)
Been pretty much flying it with the left hand only... just to keep my 4-channel education as simple as possible.

3 minutes is very short. The heli this one is based largely on can get 6 minutes from a mere 120 mAh battery. This one uses a 150 mAh, right? Almost sounds like something is binding, causing more resistance on the motor, so you burn energy faster than intended. I know the 911 is heavier than the Solo Pro, but even the Bravo SX which is about 33g with battery can still get 5 minutes with a 150 mAh lipo.
