As far as collisions go, I get about 90% of my collisions from getting too close in a scissor with a con, not HO, and about 10% from accidentally hitting a set of buffs I've made a guns pass on.
Yama, we all get frustrated. I hate it when a con rams me and flies off. It happens. Good thing about this game is that planes are free, and we never die. You're a good guy and I've flown around ya, just play for fun, man.
Don't sweat the small stuff.... that's what drives people away.... focusing too much on the 2% that maybe needs work, and not looking at the 98% that, well, just freaking rocks about this game.
