Got new drive shafts now the only problem that I have is when I throttle up, [color=#FF0000] I can hear the pitch change, but it sounds like something is popping as the blade pitch changes and then it jumps a little and it takes even more power to get lite on the skids.. Once it leaves the ground it very jumpy and hard to control. Any Help on this problem would be greatly appericated

Thanks
Tom
