Yes, I tapped at M10x1mm and spark plug is screwed on 10mm
Thread lock is sealed (Loctite 243)

Actually, you may have ignition troubles. I assume that by 7/100, you mean 0.070". If that is the case, your gap is just over 1/16" and at 16x would then require ignition and insulation to a 1" spark in atmospheric air.

If you meant 0.07mm, than damn, that's small!

In either case, you'll need a long barrel and a high propellant SOS to get the most out of that chamber.

Being so compact I would think it would be fine, especially if shielded in some padding. It would still not take kindly to being buried though, so a break-away tail is essential.

it is actually fairly easy to build a a directional antenna that can be used to locate transmitters

and no you don't need bluetooth and smartphones

yeah it might be but bluetooth for something so simple is an overkill

AFAIK it can be as simple as a loop antenna

don't ask me how to build a transmiter but I am sure duane or technician can post a schematic or at least mention where to find one

Look up "foxhunting" in regards to amateur radio, it's the sport of finding a radio transmitter, ranges of several miles.
