Yogi, as someone who cut his teeth on HLGs, you are 100 percent on regarding the stability/control issues. Looking forward to seeing the next section you put out on this. Your reply verifies some of the other speculation I was having regarding a pressure tank approach to the launch system....I was thinking about using a 3/4-inch ball valve as the launch control mechanism. Mounting a pressure gauge on the air receiver wouldn't be too difficult, but the air inlet valve might be a bit trickier. Just a tire valve stem, or something more sophisticated? Is there any info around regarding an "optimal" tank pressure? I'm just guessing, but I don't think the model will stand more than a three atmosphere impulse. My first instinct for receiver dimensions is 4-in diameter by a foot long....overkill? Has anyone tried using a twin-tube launcher for twin-engined models (like the F7U)?
