Having major problems with my tail, setup is as follows:

-"Mothed" Hummingbird FP
-Park 370 4100kv brushless w/ Thunderbird 18 ESC
-Feigao 12mm brushless w/ Thunderbird 9 ESC
-DX6 tx/rx
-Telebee heading hold gyro (also tried G90 w/ same results)

Per Castle Creations, the TB ESC's are auto-calibrating, so I have to give full left then right rudder to set endpoints.

The problem is as follows- unless I set the gyro at approx 60% gain, the tail spins even when the heli is stationary and at neutral. With it set at 60%, the tail prop is still when the heli is stationary, however- once in the air, the tail whips like mad in 120 deg+ arcs and is not controllable.

Per Castle Creations, I need to adjust my rudder endpoints so that the esc sees the low endpoint at neutral stick. Can this be done on the DX6, and would it even work?

A few guys on rcgroups have given several suggestions as follows:

-Cut down the tail blade more as it is over-authorative considering the motor is around 5000rpm/v
-Try a v-tail mixer with one lead to gyro and 2nd to the aux channel on the rx
-Set up a mix slaved to the throttle channel

I have no idea what to do. My LHS is no help- they sold me the stuff but don't seem to want to assist. This bird will fly great, it is exceptionally smooth and the power is there, but the tail isn't.

If worst comes to worst, can I at least go with the gyro in rate mode and revo mix? I apologize, I am a bit of a noob when it comes to the deep programming issues and idiosyncracies of full separates. This was to be my first foray into same, and it is becoming a test in patience...

For those interested, here is the link for my thread at RCGroups:

Thanks in advance for your help-

I would think you might be better served posting your inquiry on an electric micro heli specific forum.

You can find one on RCGroups. It is not very active relative to nitro helis but does have a good forums on the micro, mini and larger electrics.

I don't have a clue how to help but don't give up. Make a search on the internet and find someone else who sells the stuff that is willing to talk you through the set-up. It's likely to be something simple once you find out what to do.
