ok so i bought my HBK2 and it arrived today and it was flying fine. Then i went to fly for a third time and it had a weird vibration at about 30% throttle. After 30 the vibration would go away and its just very confusing. This was happening with the blades straight also. Any idea whats causing this?

Make sure that your belt is tight enough not to 'slip' and chatter on spool up. Also check that the locknuts on the feathering shaft(blade grips) are not too tight. There should be some end to end play in the shaft.

Like Bob said.

Should always do a complete inspection of anything that comes to toyu RTF.

More often than not, nothing is.

does your king have the stock motor or the 3100 esky installed, check that the motor is secured to frame, the vibration from anything loose will be tansferred thoughout the airframe, the weakest point will take the abuse and begin to fail, like stated before check belt tension, make sure the screws holding the tail boom are secure, also check the boom supports for loose screws
