    I'll throw in my 2 cents worth since I have over 700 hours flying the 640. While both the 640 and the RV-10 are both all metal 4 place aircraft, they are really not in the same class. The RV-10 is bigger, faster, more difficult to build, and much more expensive to build and maintain. With that said, if you understand the 640's limitations and have realistic expectations, the 640 is a wonderful aircraft. It has great performance off the runway, is extremely stable and easy to fly(great for IFR), has decent performance numbers in cruise, and has been easy and inexpensive to maintain. The controls are a bit heavy at cruise speed, but very responsive and balanced. It has a great useful load, but does suffer from a cramped rear cabin area. If I could make one change to the plane, I wish they would have stretched the fuselage a bit to open up the rear cabin. As it is, I still fly with my 3 kids (ages 15, 11, and 11) fairly comfortably. At 6'5" you will need to have the front seat pretty far back which will effectively make it a 3 seater. Since I built from a quickbuilt kit, I can't comment on the difficulty of building from plans. While there were a few glitches with the kit, overall there was good support from the factory and the plans and documentation were very good in my opinion.

    Christian, My plane does have the change to the rear seat, moving it back about 4 inches. The way my plane is finished, 2 normal sized adults cannot fit comfortably in the rear seats. I do have pretty thick seats (2 1/2 inches of foam and 1/2 inch plywood) which does take away quite a bit of room when your talking about a space where a few inches could make a real difference. The thinnest seat foam you can comfortably get away with would probably be the easiest way maximize the available space. The nice plush seats look good and are comfortable but do waste space. An adult sitting in back will have their knees up against the seat back. This is aggravated by the elevated floor in the rear (which brings the knees up higher where the space is the least due to the rearward slant of the back of the front seat). You could try decreasing the angle between the front seat back and the lower seat cushion. A few degrees change might not be noticeable when sitting in the front, and that could add a few inches of knee space. Sliding the front seat too far forward will bring the average sized persons knees in contact with the bottom of the instrument panel so there is not a lot of leeway there. You could also decrease the angle of the rear seats back panel to give another inch or so of knee room, but the rear seating position is already pretty upright so that may end up a bit uncomfortable as well. Moving the whole rear seat back any further and, due to the slope of the rear canopy, your passengers will be hitting their heads on the roof. So as you can see I have thought about this, but thus far the limited space has not been enough of a liability to try and make any changes.
