Slow piroette speed
Help. I have a align 700 superior f3c. that PIROETTES slow, I tried increasing the rudder end points to max. Lowered the gain on the
spartan quarks gyro ( its flybared ) I can barely do a stall turn. I have many helis this is only one that does this. Gain 60% in rate mode, -33% heading hold. any advice

No much adjustment with this spartan...

Did you try with longer tail blades?

PD

What about the other setting on the pc software? By default?

There is a set endpoint procedure. Don't remember it exactly but something like max rudder stick and press the button. Have you done that? I think the manual explained it in fair detail.

It has either to do with your gain or end point adjustment / travel adjustment.

Increase your head hold gain.

is the ball link out at the last hole of your tail servo arm?
I use a 4 hole servo arm and i use the furthest hole out on the servo arm.
Is the tail servo arm 90 degrees on your tail servo?
What type of tail servo are you using?
Is the tail box arm 90 degrees to your tail control rod?
Did you ensure there is no binding at the tail box by first disconnecting the tail box arm?
When you mentioned that you maxed out the endpoints,do you actually see the tail slider reach the very end on the tail shaft?
I have never heard of increasing heading hold gain to obtain a faster pirouette.To obtain a faster pirouette,you must increase the tail blades deflection angle by increasing the endpoints/travel adjustment,how does increasing heading hold gain increase tail deflection to obtain a faster pirouette?

Did you follow the Quark manual?
Especially STEP 2 and 3 on page 13 and 14?

Steps 2 and 3 on pages 13 and 14 does not "require" a pc with the Spartan/Quark software,it is done independently on the gyro and transmitter to set maximum endpoints according to the - "MANUAL".
Where does it say on steps 2-3 to connect to PC to achieve maximum endpoints?
I used to have an Align Trex 600 flybarred nitro,equipped with a Spartan gyro in 2010 and i "NEVER" used a computer to set my endpoints.
Why make it more "COMPLICATED"?

With a properly set gyro, the piro rate is controlled by stick deflection from neutral.

The further you go from neutral, the faster the rate of rotation.

Question #22

How do I setup my gyro for eye blurring piros?

Answer

Whilst the gyro operates in AVCS mode the tail pitch is entirely controlled by the gyro. In this mode the pilot's rudder inputs become a command for the gyro telling it how fast to yaw; the gyro then controls the tail pitch as needed to maintain the commanded yaw rate. It is also possible to command the gyro to open the tail pitch fully which, depending on the mechanical capability of the helicopter, can result to spectacular yaw rates well over 3 turns per second. To achieve this you should set the rudder endpoints of your radio to a very high value effectively commanding the gyro to yaw faster than its sensor's measurement capability. For some radios you may also need to increase the gyro's rudder stick sensitivity via the PC, PDA or detachable LCD. You may also wish to set the deceleration adjustment to a slower setting to soften the stops from such fast yaw rates
