Model Forum / Radio Controlled / Helicopters / July 2006BladeCX "orbiting" problem?
Have a Blade CX that, once it is in the air, seems to "orbit" a centerpoint. That is, after liftoff it circles an imaginary line radiating straight up from the launch point in a circle about 3-5 feet in diameter. Flybar, blades and axles all seem straight with no vibration. Restarting the 4-in-1 doesn't seem to have any effect. Any suggestions? Something in there is bent or out of alignment. No way of telling except pulling it apart and checking all the components. Check your shafts by rolling them on glass or using a straight edge. What looks straight not always is. > Have a Blade CX that, once it is in the air, seems to "orbit" a > centerpoint.

Have you tried adjusting (by lengthening or shortening) the connector from the flybar and the upper rotor. I found that adjusting that diminished it quite a bit for me. If you read the manual, it'll tell you that you want the tips of the blade to be in the same plane with each other or as close as you can get them. This can be easily seen by have a light back ground and watching the tips as it is flying. > Have you tried adjusting (by lengthening or shortening) the connector from > the flybar and the upper rotor. Yes, although that had no obvious affect on the orbiting issue. I found that adjusting that diminished it > quite a bit for me.

My next attempt to fix this is to disassemble/reassemble the entire thing. Might get lucky! Try changing the mount on the flybar to the other blade > Have a Blade CX that, once it is in the air, seems to "orbit > Have a Blade CX that, once it is in the air, seems to "orbit" a > centerpoint.

I had broken the tip of mine and replaced it with a new one with a (blue) metal tip. The weighted flybar had a little bit of drag (a tiny little bit) when it rocked back and forth in the metal tip. I didn't think it was a big deal but then I developed the same problem you have. It drove me crazy checking for bent pieces. I replaced the shaft with another one with the original plastic top and it moves smoothly again and I'm back to hovering properly. Steve |
