Ive only had my P4 for 3 days so still learning the ropes, but I'm confused. Today whilst in P mode, I was flying around manually. About quarter a mile away, trees were the only obstacle between me and drone.
Yet, I lost signal? These things are meant to fly for miles so why have I lost signal after a quarter mile?

The RF is a very short wavelength, leaves on tress especially when wet would certainly cut out transmission as would your hand infront of the antenna.Yet, I lost signal? These things are meant to fly for miles so why have I lost signal after a quarter mile?
There is also the possibility of phasing due to signal reflections of buildings even the ground/angle of antenna(45o is best) or other atmospheric conditions. 2.4ghz is really only line of sight transmission for maximum reliability and signal. The receiver in the Phantom isn't that immune from outside interference either and a strong nearby RF source could overload it but at 2.4ghz that's not often unless close to a cell tower.
Try it in open space but remember, 1/4 mile is over 400 meters. You are only allowed 500 meters and line of sight at all times so you won't be flying miles.

Fair enough. Cheers for that.
And to be fair, it probably wasn't even 1/4 mile, just guessing, and I have no intention of flying miles away haha

Other drones? I've been 2k out with no problem, but this morning got weak signal warnings and it was +/- 100 yards out (over the sea, and I was on the beach, so nothing in the way)There is also the possibility of phasing due to signal reflections of buildings even the ground/angle of antenna(45o is best) or other atmospheric conditions. 2.4ghz is really only line of sight transmission for maximum reliability and signal.

Is that legal? Large gathering?https://www.youtube.com/watch?v=t7bqkMgw87Y
Awesome footage though!

Water can do funny things to 2.4ghz if you're low over it. That's why a few people have lost theirs flying over indoor swimming pools, 5.8ghz isn't an issue though.
Don't suppose there is anyway to upgrade a P4 to 5.8?Gassing Station | Photography & Video | Top of Page | What's New | My Stuff
