This thing is probably not so easy too shoot... not so much because of speed, but because it's hard to get interesting angle, which would show their speed and ability to fly low and accurate. To be honest I have no idea how I would go shoot something like this, except that I would set remotes straight under "gates" where planes have to fly through... if allowed of course.
Otherwise some photos are nice, some are hmm... a bit less nice (no offense
). Another thing I don't really like is that they look extremly compressed or extremly croped. If it's first option then it's no big deal since original file is something completely different, if it's second option then...
