Bootleggin' again here. Yeah, 727gm, you're right. I've got a fair amount of time in piston Beeches and "3's". If you flew a Westwind like those... look out! Trouble lurks on the horizon for sure. They're different creatures. We used to line up, get the RPM matched up, then advance to takeoff power during the roll - on the left engine alone. As the tail would start to become light, THEN, we'd start in with the right engine, eventually sorta' matching them up at takeoff power. At our weights, it was the only way to get them off the ground without torquing into the dirt off the left side of the asphalt. The tail end was HEAVY. Yes, the gross on most of them was 11,230. We typically flew them between 11,000-14,000#, in the days prior to deregulation... but I'll never admit to that in person.
N38L(SNB-5>TC-45J/WW-III) *Never flew it.
N202GW(E18S/WW-III) *The favorite @ Great Western Airlines. We had N8794 (A C-45 'ATE'), N10VT, 12VT (Dee Howard), N11AB (Dee Howard & ATE... so we called it "Abortion"), N201GW, N202GW, N521GP, N342T (Hamilton).
N5653D(E18S/WW-III) *Flew it @ Stage
N909GP(E18S/WW-III) *Flew it @ Check-Air & Mountain Air Cargo (As well as N153GP)
N961GP(G18S/WW-III). *Flew it @ Stage
They're interesting beasts, for sure. We called them "Whirlwinds" or "NBF's". The latter acronym stood for: Needle-Nose Bug Fu--ers! Like anything, once you get used to their quirks, and learn to respect it for what it is, they're pretty cool. Scary at times (especially the early ones), but cool.
