Capone, Yes I actually should have stated to unplug the batt...My bad...Lol... There is a difference ! Good ya asked...Unplug the battery then make your adjustments. Then plug in your battery with TX already on, and see which way the nose is turning looking at it from the tail...If the nose goes left, turn the prop adjustment to the right...Only a little..The nose goes right, turn the pot to the left...Just don't forget to unplug the batt each time your adjusting...
