The inefficiency is derived from the long, shallow "combustion chamber"
formed by the rotor at its top dead center. Flame front progression is
slow to advance, resulting in slightly incomplete combustion, and
results in more heat going out the pipe, rather than being turned into
motion.

I would hope that I know this. I've built a rotary and had it running on
an airframe, alas not without problems (not with the rotary itself, but
part of a builders learning curve)

Did you end up dumping or keeping therotary?
