No burden, I enjoyed the education. I remember burning a 1/4" scale P-40 when I was a kid. The polystyrene supported a flame, which surprised me and it melted into a quickly solidifying glob. That pilot suffered a terrible fate...LOL.
Now you have me wanting to experiment. Maybe I'll try to torch the clips shard, if I can find it.
