Tail wag that i can't get rid off.

Butch B · 12-23-2010, 02:16 AM

I can't seem to get rid of a vibration that is upsetting my spartan gyro and causing a tail wag. It doesn't seem to matter what gain i run, it's still the same.Any ideas?

which Spartan?
which servo?
Picture of mounting might be helpful. From my experience I've had some that want the metal plate, others that don't. If everything else is good, I would experiment with mounting & tape.

A little more detail would help. Fresh build? Experienced heli? Was working fine? Never flown? Engine broke in? Which servo? Servo ball from center? Fast tail wag, slow tail wag? Radio set up right?

It is a spartan quark gyro with a outrage 9088 servo. It is top mounted, but have tried different locations with the same results.It is mounted as per spartan instructions with the steel plate. I am also running a dx8 with an ar7100r recevier.The helicopter has flown for about 10 months, it had been running well but started have tail problems about 1 month ago, but then had a crash so rebuilt. Replaced all the bearings,main shaft etc etc. but still have this problem.

how long ago did you switch to the dx8. Would it happen to be about the same time the tail issues began a month ago?

It probably would be.

I am running a spartan on mine with no metal plate, using the Zeal tape and a velcro strap. Tail is solid..

Are you aware that the dx8 uses different gyro gain settings.

I have a spartan on mine with standard tape DS650 with no tail problems.
Have you checked the boom supports??? they can make the tail wag
