Yeah, it’s a strange selection given the handling issues of the oxidizer.
It also has a reputation for hard starts -- yes, it's hypergolic, indeed
one of the first hypergolic combinations discovered, but it has enough
ignition delay to be a bit marginal.
If I were them, I'd worry a bit about whether successful results with one
batch of turpentine today would translate into success with another batch
tomorrow, given that the composition is not really standardized. I would
particularly worry about whether smooth starts today would become hard
starts tomorrow.
