Have fun finding it and no you won't hear the "sonic boom". I had one last 6 flight of which 3 were the F10-8 with that 8 second burn. That is really cool. Don't spend that much time with the paint as it has a tendency to get beat up with streamer recovery anyways. It's a given if you don't get a visual on descent, you're going to lose it unless it lands on you. If you use a metallized reflective streamer, run some scotch tape on the edges and fanfold the streamer. The tape though it adds weight, will keep the streamer from fracturing and breaking. Had that happen a few times. The fanfolding gets the streamer to rattling and out in the country, unless you have a hearing impediment, I've had my "ears" direct my "eyes" to get that all-important visual fix.
I remember one flight with a two stage where the rattle caused me to turn my head 120 degrees to see the rocket coming in. Landed in standing corn and I had the foresight to have a beeper on the thing too. Walked in 8 rows towards the sound and picked it right up. Remember, one's ears can be an important recovery tool.
The only other advice is you could get lucky by flying at a large launch with many folks running around recovering rockets. You lose yours and someone finds it, most fliers are honest and will return them to the RSO/LSO.
If I stumble on a large rocket, I mark it with a waypoint on my handheld GPS. If it's small, I say screw it and take it back to the table. I returned a rocket with a tracker one time and the flier was flabbergasted the RSO paged
him to get his rocket. He flew it and was going to hunt for it later. Kurt
