what setting can i start with my 4-1 for the gain and perportinal?

I would start with the gain adjustment first. Turn it clock wise to full, and then adjust down until the tail stops wagging. Adjust the Proporational using a fully charged battery with the rudder trim in the netural postion, until you get the tail from wanting to spin left or right during hover. Make adjustments to get the helicopter flyable and then very small adjustments to fine tune it in. If you have the manual follow it close. Good Luck!

im still learning to hover, my heli likes to go right when it gets light on the feet.
its a blade cp btw, and i had it for less then a week. cant hover at all, tryin to follow radds flight school.
