A little off from the OP's question, but the issues discussed are precisely why I chose to build a
Bearhawk Patrol instead of the Highlander or SuperStol... I'm a big guy, and my family members are larger as well. Pick any two of us, and put us in either of the Just Aircraft designs, and we're either at gross weight, or over - before adding any fuel at all. The Patrol was designed to handle two 300-lb people, full fuel, and up to 100 lbs of baggage, and remain well within the CG range. It's a tandem-seat design, with about 31 inches of elbow room. Very roomy and comfortable, and fantastic visibility.
The stated takeoff / landing distance is 250 ft with about 1700 FPM climb rate, but that's at gross weight with zero wind, and is a pretty conservative estimate for the 180-HP version, although probably pretty accurate at gross for the 150-HP powered examples. At OSH, I got to fly in their 180-HP demo plane, and with a 200-lb pilot and my 310-lbs in the back seat, we were off the ground in well under 150 feet (about 10 knots headwind), and had to level off at pattern altitude about halfway to the end of the runway. It's a rocket ship with 180 HP and constant-speed prop, for sure! The fact that it cruises at 140-150 mph (depending on engine and prop combo) and stalls at under 35 mph makes it the ideal airplane for my mission. It seems like everyone who has ever flown it wants one - including several guys that previously built (and still own) 4-place Bearhawks who are now building Patrols!
"QuickBuild" kits are available, but even with the QB kit, there is a lot of work to be done. It's not like the Van's design, where it's basically "insert tab A into slot B" - there is no "build manual" so there's a lot more effort involved with interpreting the plans and figuring out what to do next. But it's a lot of fun, and you wind up with a LOT of airplane. Their website is

My hangar-mate has a
CH-750 with the
Jab-3300, and absolutely loves it. He jokingly refers to our 7,002-ft long, 150-ft wide runway 18-36 (KTKI - McKinney, TX) as
"The World's Widest Runway 09-27"... He likes to fly to a friend's grass runway just up the road, and has flown it up to Mexico, MO to the Zenith factory, but at the ~90 mph cruise speed, and with the very light wing loading, it can be a beating if there is turbulence and/or headwinds. It's a great plane for "dawn patrol" and "hundred dollar hamburger" flights, though, and he really enjoys flying it.
