Friend of mine 6-8"tall went for a ride with me. Yes - it can be done :)

Build log for Waiex kit #81
Update December 2016. Well over 13,000 visits to this website! Wow and thanks everybody! It's my first update in 2 years, so here I go: I've got almost exactly 230 hours on the plane now, and lots of changes over the last two years. I absolutely LOVE flying this plane. Very fun to fly, economical (I only burn premium mogas and cruise at 4.8mpg/148mph), and get lots of attention wherever I go. I've been over 180mph at WOT.

1) I did change to the Bing carb and the infamous "burp" that the Jab3300 is known for when using an Aerocarb completely went away. I think I finally determined root cause of this issue for me. I believe it was actually caused by a combination of several things. The original MGL FlowScan fuel totalizer in the fuel line created a very restricted, and low pressure fuel flow path. Even though I had AN6 lines and a heavily insulated fuel delivery system I still got fuel vaporization burping. The orifice for the FlowScan was probably 1/8 at best. The combination of this with the higher cowling temps of the Jab3300 caused fuel vaporization - resulting in the burp. The Bing with the fuel pump and float bowl addressed this issue and didn't cost me anything since I still had them. MGL has since come out with a couple of better designed flow cubes that would probably take care of it. I do prefer the Bing though, no messing around with the fuel leaning process. I also have electric heat on it, so no painful warm air inlet design.
2) I installed electric flaps in February of 2016. Had surgery on my left wrist and wasn't strong enough to pull manual flaps after that. Electric flaps are FANTASTIC! Wish I would have put them on originally. One less thing to chase with your left hand.
3) Had to rebuild the top end of the Jab3300 at 178 hours. It was an early hydraulic lifter version and due to lack of oiling to the # 1 cylinder exhaust valve, took out the valve guide. It also ground down the tips of the exhaust valve pushrods on 4 of the cylinders. I updated to the newer full hydraulic system and everything seems to be okay after an additional 50 hours.
4) If you polish your plane, PAINT THE BOTTOM OF THE WINGS, FUSELAGE AND STABILATORS. Also, paint the bottom of all your control surfaces. Polishing the bottom of the plane is a worthless exercise and you will eventually get corrosion on it since it's not fun to crawl underneath and polish it- which means you won't do it...
5) Gear fairings and wheel pants account for 9mph additional speed on my plane (GPS verified). I always fly with pants and fairings on if possible.
6) If you have a standard gear, Jab3300 configured Waiex, just put differential brakes on it for safety reasons. See below comments regarding left side crosswinds.

Permanent Note:
Methods to take off with port side crosswinds in a standard gear, Jab3300
Waiex. When crosswinds approach 9mph at 90 degrees, the Waiex WILL point to the left side of the runway when you throttle up and take you out into the weeds. After 230 hours in my plane, below are methods I've learned to help mitigate this issue. That being said - I absolutely NEVER takeoff in 90 degree crosswinds over 11-12mph. Nada. It's a combination of the big Jab, standard gear, not much weight on the tail wheel, and lack of rudder authority at low speeds on the Waiex. Been through one flap already and should probably replace a buggered lower wing skin and leading edge as well. Only those with differential brakes appear to handle this very well. I've never met a customer built Waiex driver that will privately tell you anything different. Landing isn't an issue though. I've landed with 12-15mph direct crosswinds on both sides with not much of an issue.

Method 1) Setup the plane for a parabolic path takeoff. Point the nose at the right side of the runway about 400 feet from your initial point - and run it about 90% throttle. You will be pointed close to straight down the runway when there is enough speed to get the tail up and get some rudder authority.

Method 2) throttle up slooooowly (like 2500rpm) so that you have maximum tailwheel authority. You may still point to the left some, but not nearly as abruptly as a full throttle straight takeoff. When you can get the tail up, then WOT.

Method 3) Take a passenger. The extra tailwheel weight pretty much takes care of the issue.

Method 4) Put differential brakes in the plane. The vast majority of Waiex drivers end up doing this - and I'm doing it this winter myself.
