Javelin,
I have. I've cleared Rocket launchers for the RAF, external camera balls for the police, assorted spats, cameras, fairings, fins, external baggage carriers, doors, etc on assorted private aircraft, upgrading warbirds to public CofA, ballistic parachutes. This is what I do! I'm not saying it's quick or easy, I am saying it's possible, under the current regime, which incidentally is much easier than the one 5-10 years ago, but you could do it then as well.
If you've tried and failed, tell us the details and perhaps I can point out where things went wrong ?
