hi,

I got almost the same problemes.
both my stratusses, does sometimes do a nick movement (tail moves 20 cm up and down), with out i move the sticks.

i have cleaned all ti servo plugs, switch to 2.4ghz, and the problem is still there.
I could fly more flight with out any problemes, and suddenly it's there again.

I do hoewever not have to land the heli, to stop the probloem.....

IIf I, on the bench, give almost full backwards elevator, the swash (and servo monitor) shakes

I have now tried another 14mz, and have not seen the problem for 25 flighs....
I have send my 14mz to Robbe

Same problem, except it was my ailerons on two different 40% planes and a jet. the worse part about it is that i could only get it to glitch during flight and it caused me to change every servo in the wings of a biplane, sent it in an got fasst and haven't had trouble since.

Hi

I talked to Robbe Service department, before I send it.
He told he was sure that it was the potmeters that is broken:arggg:

My 14mz is 2 years old.....been used for REFLEX for about 6 month, otherwise only for my real helicopters

Two years ago, a had an 1.5 year old )z, were the potmeters also failed.
Robbe told me that the potmeters in the 14 is another type as in the 9Z

I have ask Robbe, what I can do wrong...:confused::o
