Too high torque on tail when climbing fast ?

[xircom]

Hi, today got the first flight - fantastic. Only one issue bothers me quite a bit, on high headspeed, the heli turns quite a bit, in really fast climb over 90 deg) . Did I made construction mistake ... or ? I run 4S 3025/10 and 401/9254 on the tail. I felt like the stock-tail blades are kinda cheap plastic, I can bend by hand easily, otherwise the tail as such holds really well - almost 100% gain on 401 in HH mode. Maybe also I shall fix the normal mode first, there the heli turns continously a bit, in HH it doesn't. Thanks a lot !

How long tailservoarm are you using?
Im around 15mm on my Lepton.

I set up the tail in normal mode on the bench with the pushrod 90' to the servoarm and with the tailpitchslider in the middle of the tail, adjusts limit and the switch to AVCS and fly. :)

I put linkage ball 12,5 mm form the center of servo, Futaba round plastic shield on 9650, works really good.

actually I have got 10mm as per manual. and tail side, I used the hole (out of two) which is closer to the rotor, and when I measure the distance 90deg, then it's 20mm. Servo-arm and slider are just 90deg both midstick. Limits are adjusted, and it flies well in HH (AVCS) mode, just only when high power climb-up, then heli starts to turn (clockwise seen from top, if I remember right).
