Yeah! I know what you mean, trees are cool unless you get stuck in the top of one. Fortunately I've never had the pleasure. However I do have a bird threat. The dragon fly's and bumble bees that charge the aircraft from the trees, soon learn the hard way that them rotor blades kill. POOF bug cloud...
I think it's only a matter time before I hit a bird or a bird runs into me. One time a whole squadron of small rice birds came out from behind the mango tree. They all saw the chopper at the last second and the 60 or so birds divided into two, just like a school of fish when a shark goes through it. I was all, whoa!!
Then there's the guy up the road with pigeons. When he releases them, they do sometimes circle low right through my air space. I love birds, I'd hate to hit one or two or three... Not only that, the aircraft probably would get gross and damaged some how. A pigeon or a mynah bird is a big contact for a 450 I'm sure. Li'll rice birds, watch out!!.. Heck I got NAV lights, what more do they want; an IFF beacon, LOL!!
See you in the yard buddy!
