Sounds to me like vibration interfering with the gyro. Are your blades balanced? Do you notice any bad vibes? Also, is the gyro mounted in special vibration dumpening foam?

hi. i dont see any bad vibs on it. I guess its got the usual vibs, they stop when head speed is good. blades are balanced, no tracking. I tried using some foam sticked on gyro but still the same.

gyro is piezo 310. i`ve been flying with it for 2 months whith no problem. The guy at the shop told be it was my brushed engine, but now i`ve put on a hacker b20 15l and have the same problem. thanx for those quick replies.

is your gyro close to your esc? some have reported interference if too close. try moving the gyro as far away from the esc as possible.

Mine does the same thing. do you have the tail servo and gyro mount? If not order that, and the diy tail pushrod kit. It really calms the tail down by getting rid of all that slop. The tail control on the shogun is crappy stock but the upgrades that are available really stiffen it up. I ordered mine from Mjp carbon.

gyro is taped on the side of heli ,above pith servo. It worked for two months and suddenly started to glitch. I guess its just broken. waiting for those up-grades. What gyro should I get? ,heading lock? is it usefull?

all i have ever used was a heading hold gyro and futaba its really a matter of pilots choice.
