I am a complete beginner pilot with about 30 flights (since x-mas) on a CX. I am getting pretty comfortable with it, but have some questions. I'm concerned that it "too" stable for how I'm trying to fly it now. I have the common problem of trying fast inputs and having the flybar contact the blades. I also notice that while it is great for indoor flying, it isn't very fast. I can handle it OK in a slight breeze (1-3mph) but it can barely keep up with the air movement. Also while it initially leans (bad terminology I'm sure) and reacts quickly to elevator or aileron input, it quickly "corrects" and "resists" that input. Put another way, I push the stick forward and it dips in and heads forward and then the flybar forces the upper blade to counter-act and the helicopter levels out.

Questions:
1. I'm sure it is, but is this normal? Would a non-coaxial aircraft not perform this way? In other words, would constant forward elevator eventially cause the nose to point to the ground?

2. How much can I adjust the flybar to change this characteristic? I've gone as far as removing the copper portion of the weights (leaving only the rubber sleave) and it makes a big difference. Was this a stupid thing to do?

3. Do I just need to upgrade to a different kind of plane? Would a CP be any better -- or too hard to fly for a beginner?

Thanks in advance for your input.

I have had a CX and a CX2 for some time now, and have yet to encounter that. Sounds like your putting way too much input into the controls. Just try to make smaller movements, and you will be fine. Even outside with NO wind, it will behave ok, as long as you are smooth with it.

It's not meant to be thrown around, just hovering and mild forward flight.

If you want to get into forward flight, try a CP, but they are pretty tough from what I hear.

Good things come to those who wait, and PRACTICE!

Instead of removing the flybar weights move the servo pushrods out one or two holes farther out on the servo arm. That will make the heli more responsive without making it unstable.

Thanks

Moving the control arms further out on the servo arms helped quite a bit. Haven't been able to test outside but seems much better indoors. I am only angry that I didn't think of this myself

hey couple more pieces of info for you, dotn remove teh weights on the flybar, jsut shorten it, i did it to my stock flybar on my table. just make sure its perfectly even and balanced. also found the aluminum swash has a bit more throw to it, so that'll help to. I Oh and for outdoors, LOOSE THE STOCK TAIL BODY, get one of the carbon shafts. i fly mine up to 6 mph winds without to much problems ( now this doesnt include hover,cause that just aint happening) also you can try, which i am workign on now is soldering the brass wieghts on and removing the rubber. dont take off to much weight though, heli becomes a major handful.
