Just saw this update on Big Radials Facebook!
" A little sneak peak into how the sausage is made today and a big step forward on dialing in the flight model and engines: 40,000’ @ ~0.8Mach.
Just like this JetStar, we’re racing towards a release shortly and will be doing a TON of updates post release to make this a beautiful vintage jet to fly. We really hope you enjoy it and remember #FlyTheDamnPlane"
