the burner is just an aluminium can.
I'm trying ground up match heads with C23, when the alcohol is almost gone the side of the can gets hot enough to ignite the mtach /glue that is holding a simple piece of string.
I get 9 minutes from 60 ml of metho, that should put it fairly high.
If That doesn't work I'll use a .22 round with the projectile removed and replaced with a simple plug.
I have some electric matches, so maybe releasing on a set GPS height might be better.
