No sweat, Alex. We were a tad confused, that's all.. and that's nothing new, at least for me.. Your call if you want to move it.. not necessary. I just thought that might be a better place.. depending on what you mean, that is. I thought you meant viewing the aircraft path using an on-board camera to a ground receiver or something like that. I've seen that done and it was pretty impressive, and that was, oh, 10 years ago. The technology has improved tremendously since then, mineature devices that don't draw much power.. weight almost nothing.. can easily be put on an RC aircraft to either record on board or transmit the video to the ground for viewing or recording... or both.

But we're still a bit confused. I'm not sure what you mean about the home "arrow" altitude, and so on. Are you talking about on-board GPS or something like that? For the edification of those of us that may not be savy, if you wish, please explain.
