I knew about this months ago but was asked not to bring it up yet on my blog. I had a few phone conversations with Charlie Sovoie about Quest when I drew up the new MONSTRA kit instructions for Aerotech.
As black powder engines have gone up in price, competitively priced 18mm composite propellant engine can now be produced. These engines will probably be in the B, C and D ranges.
I would expect the official announcement to be made at the upcoming NARCON.
