Electrical noise coming from the ESC is interfering with the gyro / tail servo function because someone took the ferrite ring off ?

The vibrations you are all seeing is due to the fact the head is unloaded but also mainly because of the problem. The head being unloaded just amplified it. Also he still had the tail blades fitted in the video

Stripped TT gears? Grub screw on the tail shaft backed out? Bolt on the tail slider arm backed out?Originally posted by Made2Fade View PostThe vibrations you are all seeing is due to the fact the head is unloaded but also mainly because of the problem.

It's Stuart, so I''m guessing maintenance rather than a failure Love ya really mate ha!

Give up? Come on Harry this is Stuart you should know... look at the clues... bearings... i took the tails blades off which led me to finding the problem

It would help if actually video'd the tail?? & used a camcorder not a calculator
Blade grips on backwards??Yes the big sigpic is coming backComment
-
No bolts holding the tail grips on? or thrust race washers on backwards small/large id mixed up? or no bearings at all? or a combination.........
Glad you guys sorted it.
