I had to replace some parts in my Venture 30 head with some Ergo parts, and install thrust bearings to solve my tracking problem with that heli... tracking would go in and out from flight to flight. Seems OK now, but it cost me $50 or so for parts and shipping. If the Venture 50 head doesn't come with thrust bearings, you'd probably have the same tracking problem with that.

Anyone know if the Tiger 50 has thrust bearings in the head?
