@Stefan__Powell@DawnAerospace That's incredibly awesome. The 20N engine looks severely overexpanded, so I'm wondering if you tested it in an adjusted atmosphere as well?
@JohnStaats_WIR Just finished the last 100p of your book a few days ago after being shelfed for a few months. Thanks for the insights, amazing read! How's that board game coming along?
