I have a problem, or so I think I do. Relatively new to the hobby have been flying for about two or so months so any help would be great. I have a Mini Titan with a GY401 and a futaba 9650 on the tail. My question is my tail holds fine if I am just hovering haven't really been able to check in FFF but when I increase collective to do a fast climb out my tail blows out and begins to spin counter clock wise I am guessing soem adjustment should solve this problem just not sure what adjustment to make. By the way travel on the servo is good no binding anywhere on the tail and my gain is about 75% any help would be great thanks....

HI,
What make of TX are you using? In terms of Gyro mode there is a differance between JR and Futaba.
In JR, over 50% is Heading Hold, below is normal (or RATE) mode. BUT, on Futaba you have a full range of 0 - 100 in both heading hold and in rate mode, there is an extra section on the display that tells you which mode you are in.
Norm is normal or RATE mode, and AVCS is their identification that you are in Heading Hold mode.
If you are in the normal mode the tail can swing when you apply power unless you add some mixing, but in HH mode the tail should remain steady. I would suggest if you have a Futaba TX you check this.
Hope this helps,

Hi,
Thats based on the JR system and has the same menus as the JR3810, I think. The below 50% RATE mode, over 50% heading hold mode method applies here.
Check you have the limit pot on the gyro as high as you can get it without binding at max control throw with the gyro set below 50%, as here the servo will act normally. Remember to reset it before flying.
Also your rudder travel adjust should be around 100% each way. If you have had to set it very low, move the ball on the tail servo in a hole and try again.
Also, have you set your gyro gain by flight testing? or is this just your starting point. It may need to go higher as long as the tail dosen't wag you are OK.
Hope this helps.
