have a pair of them in my sukhoi wings, was fine for first few flights, yesterday I turned on the plane and it was 'pulsing' is it bad? I didnt fly as it didnt seem right... Thoughts? Warrantee or anything? They are a few months old now.

Hi JohnVH,

Depending on your description of "pulsing" it may be simply the ball bearinged servos seeking center. If you feel that this is more than just normal movement for a ball bearinged servo, then yes, I would definitely recommend sending them into the service center for warranty.

I hope you find this information helpful. You can also reach our Futaba support technical team at 217-398-8970, or via fax at 217-398-7721.

Are the servos on extensions? This happened to me last month so I replaced the servo and the new one bounced too. Then I started looking into it and was told to replace the extension with one that has gold plated connectors. It worked and subsequent tests of the old extension results in more bouncing servos.

Thank you Krysta, IMO it is pulsing more than a normal one should, it moves alot.

Damon, it is on a Y, I will remove it and plug it directly to an RX and see if that cures it before sending in
