After a slight accident my Blade CX2 became a bit shaky, and a little more difficult to control. The upper and lower blades are not damaged at all, and seem to be in perfect condition. The inner shaft seems to be unharmed too, although I would consider it very difficult to damage it before breaking off the blades first.

I suspect that the problem is caused by the stabilizer flybar, but that doesn’t seem to bend that easily, and I can’t really tell if it’s actually bend. But from what I can understand, just a slight bend on the flybar, could be causing this problem. Correct me if I’m wrong.

Everything else seems to be just fine, and the hit wasn’t that hard. What could be causing this shaky reaction on my Blade CX2?

Thanks

Yes, they can just fall off the coffee table and bend slightly enough to cause some vibration or what not.

Also, it can bind; make sure the ball links are on; the top one can come undone easily, and make sure it moves ABSOLUTELY freely;flick it and it should bounce up and down a couple of times.

I guess I should buy a few flybars just in case.

hey man i hope this helps. i also had a bad crash tonight and my blade was vibrating very badly. i took the entire heli apart to check the rotor shaft to see if one was bent cause it seemed to be so. but after rolling them on an absolutly flat surface they were both perectly straight. i then used a straight edge and found that the flybar was indeed just slightly bent. after re-assembling the lil bird and straightening the bent flybar i tested it and i found it to be absolutly shake free. i have to flybar a stock and a modded one that is only 4.5 mm in length. the shorter one is almost completely impossible to bend and give incredible response and control but is somewhat unstable if you dont know how to control it. and i mena unstable as in it isnt to likely to stay in a exact spot in a hover. then the stock flybar gives incredible stability but with a loss of control. i suggest getting a new flybar and using it as your main but when you get froggy then switch to the shorter one for more high flying fun. start out in small increments such as 1/2 inch when trimming your flybar to find the right feel that you like. good luck,chris

Some good points Chris;

I bought an adjustable flybar from a guy on E-Bay, I'm hoping that'll help Me with determining the right length.


RCar, You can straighten them yourself. If it is just slightlyt bent; say in the middle out from the hub; use your thumb as support on opposite side and gently bend it straight again; otherwise you will put a second curve at the rigid hub and you made it worse.

If it's bent right at the hub; meaning that it is straight but not with the hub; then don't use any support ant bend the whole thing until aligned and parallel with the other side and hub.

You might buy an extra; I've bent them so bad that I could never get them to fly perfectly again until I replaced them.

When they are bent rather badly; I have a polished piece of marble and hit them with a hammer as I roll it around with the weights off the edge. That gets them pretty straight and also kinda cold hardens the steel so that maybe it will be more springy and not bend the next time.

I personally dont recommend trying to straiten the shafts yourself, especially the outer shaft. You will never get it perfect. We have tried time and time again.....


The things that you need to check for after crashing are the fallowing..

first, the blades.
then check the flybar.
next check the shafts
then check the blade level, make sure they are perfect. You may need to adjust the flybar linkage to compensate and/or the servo linkages (rare) Your manual will show you how to check for this.

Hey crazychris,
Your modded flybar is "only 4.5mm"? That's kind of short (only about 1/4"). Are you sure you don't mean 4.5cm?

I have read a few posts and such about the shorter flybars, but i cant figure out if everyone is giving a measurement from one side of the flybar or the overall total length. Im interested to know.
