Today my friend and student hurt his nice new plane with his 2.4 9303 JR. According to Horizon if the cute little antenna isn't bent at 90 degrees or the antenna is pointed directly at the plane they can loose the signal?? Don't ask me, I don't have a clue but I have seen a number of the 2.4s loose signals for a couple of reasons. So far the only real plus I see is not having to use the pin board. 2.4 is not fool proof, just new.
