I love the expanding tails on your engines for "aditional thust" :P

Thanks, as you can hear, the later tail is tuned to the valve head. it runs nice and even. This baby rips...for a quarter of the fuel used compared to my valveless, it has about the same thrust. Working on alternative fuels for flight :)
