Steve Colman Posted October 27, 2008 Share Posted October 27, 2008 After a week i've just about got the knack of controlling my Esky Robins but I now have a problem.After a particularly hard impact with a non moveable object the heli now has a problem with excess vibration which is particularly apparent at the tail. It is perfectly stable and controllable but appears to be shaking itself apart. The fly bar has a very slight curve but which is only noticable when rolled along a flat surface. I also ran the motors slowly without the fly bar and the vibration is still there so I think said fly bar is not the problem. And, a visual check of the rotor shaft doesn't show anything obvious.Anyone have any ideas please?Steve. Quote Link to comment Share on other sites More sharing options...
simon barr Posted October 27, 2008 Share Posted October 27, 2008 Can't help you there, Steve, but I have just flown my Blade from the dining room through to the sitting room whilst the wife was trying to watch Corrie... Quote Link to comment Share on other sites More sharing options...
Alan B Posted October 28, 2008 Share Posted October 28, 2008 Hi SteveNormally vibration as you suggest is normally down to a slightly bent main shaft. Not normally apparent to the eye on the copter. Take it out an roll it across a piece of glass. Check the pitch of the blades also when running the motor. Hold it down on the floor and run the motor and see if the blades are running level with each other.Al Quote Link to comment Share on other sites More sharing options...
Simon Robinson Posted October 28, 2008 Share Posted October 28, 2008 Steve,This a problem for anyone with a helicopter as it can be a number of things! Even If the shaft does not look bent the slightest damage to it will effect it. It only needs a slight movement to up set you heli. Is the tail twitching from side to side? I have a Blade CX2 and if the tail twitcties you normally have to adjust the "Gain" pot to correct this problem. Hope this helps.....

Steve Colman Posted October 28, 2008 Author Share Posted October 28, 2008 Thanks guys,I have now sorted the problem; it was only the top blades out of alignment and unbalanced ( pretty basic huh ). Two new replacements and everything is in order again. Quote Link to comment Share on other sites More sharing options...
Owen Hailey Posted October 28, 2008 Share Posted October 28, 2008 hi SteveThis is a common thing that happens to the cx helis the blades are a bit prone to getting bent and if you put a strip of glass reinforced sticky tape over the leading edge of the blade it makes them less prone to damage and stiffens them up and also improves lift I have made a set last over six months by doing this as they will not brake so easy.Robins 22 the best Owen.
