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.
I keep hearing about this cone of silence. In practice, I don't think its a big deal at the range we fly, though I suppose reciever installation could make it more or less likely.
I've pointed the tip of my 2.4 antenna right at a 2.5m glider that was way WAY up and couldn't force it to loose control or drop a significant number of frames. Your mileage may vary of course, but I just don't think its a big issue.
