On my Blade I am having issues with the tail motor. When I first start on a pack the Nose wants to turn right so I move the trim all the way to the left, after 30 seconds to a minute the tail is so weak I have to move the trim all the way to the right and hold the stick to the right about half way to keep the nose straight. Would a DD Tail help this or is something else I could do?
Because the tail is controlled by a motor it will do this with or without a DD tail setup. The DD tail setup is only for improving the stability of the tail. And yes it does do a wonderful job. The tail is more responsive and the gyro seems to work better at keeping the tail in one place. If you want a heli that will not have to have the tail adjusted every flight, I suggest getting a belt or shaft driven tail heli like the MX400, TREX, Shogun... and others like them.
