Hello
OK here goes....I have just finished building my 600N and just when I thought everything had gone to plan, I come across the following problem.
I am using 9255 on cyclics and 401/9254 on tail. After setting up head I moved to the tail/gyro etc but found when I turned on the tail servo was jittery and even seen to be creeping. (I should point out at the this stage the 9255 have always been very noisy!!).
At first I thought 9254 was faulty so I plugged in other servos (without going through Gyro and they were fine). So I thought it was gyro and set about elimating any chattering. As I am mounting gyro at front, it is righ on top of the two cyclic servos so I suddenly thought it might the the servos chattering that is making the 401 do wierd things.
So I then disconnected all cyclic linkages to check if they were correct length ie not pulling on servo and making them strain.One was a little tight so i corrected it but still noisy.
I then realised my head (Kasama) is quite tight but guess this is no problem for the powerful 9255's. I also noticed when building that no much how I lube it the tail slider is fairly tight.
Could any of these end up affecting the tail servo? It is fair to say it's better than it was but still have one very noisy chattering heli, which I hate!!
