I had the chance to completely tear apart a CZAW aircraft. I am a scratch builder and I know the parts really well. I looked over every inch of the CZAW plane and it was identical. It even still had stickers with the same part numbers ZAC parts come with. The only differences that I know about is gear channel, 6B5-7 is taller than the US version. There are also 6 stiffeners on the gear channel to support the gear. I have the composite gear and the taller channel. The front spar looked identical to mine and everything else measured out the same. I did not measure the skins though. There also was an extra rib in the leading edge of the wing. As for the quality of the plane. Exceptional Quality! I was very impressed with the quality of the plane, as well as the little details. I have seen and worked on a few QBK here in the states and I have seen them when they come out of the crate. The plane that I disassembled would put any of them to shame when it comes to the quality of construction. The owner became concerned with his safety after an incident and parted it out and then ran over it with a bull dozer. I understand that he offered it to ZAC for testing and they declined. I did not see any difference in the CZAW plane and the one I am building from plans. I was really looking for the smoking gun in the difference and found very little. My gear channel is so much stiffer than the stock ones, it is unreal. Those stiffeners really do the trick. I keep looking at my rear spar attachment and wonder. I looked at the CZAW one really close and it was identical in every way. The plane had 360 hrs on it and there was no sign of damage. I did not take the wings apart, other than to remove the tanks, which I must say were a work of art themselves. They have top mounted senders that were recessed in the tank, so that they will fit under the skins. Very nice work. So, the only difference I did not check on was the skin thickness used. Other than that, I found no real difference.

You don't need to modify an aircraft at all to lower the maximum gross weight. You just lower the max weight on the certificate. It's done all the time with LSA or with experimentals that the builder wants to fly using the LSA rules. Do you think the all of these LSA's on the market just happen to have a max gross of exactly 1320 lbs, the maximum allowable? They lower it when they need to to meet the rules. Don't assume that the lower gross weight airframe necessarily has less structure. (Although it could since it's all about G's.)
| Quote: | From what I understand and have read is that the European XL uses the much lighter composite landing gear to reduce airframe weight to achieve a reasonable useful load under the lower gross weight limit. Others from Europe have posted that the aircraft is identical other than that. (Britain has an elevator trim spring connected to the flaps as a required mod too)
Also, I believe, the Netherlands allows registration under the Microlight rules or the homebuilt rules. Not sure if they have the same weight limit.

The CZAW airplanes imported to the US are probably nearly identical to the US kits, but the planes they built for the European market might not be.

Simply lowering the max weight on the certificate also lowers the
useful load because the empty weight remains the same.

Sorry to say but you are wrong. My friend Carlos have an CZAW XL parked next to my kit and is exactly like the one I am builing. Skins, dimmensions, materials. etc. and I can assure you that the workmanship quality is superb.
What has been told about the weights is also incorrect. You can declare a lower weight in order to get the EU LSA certificate, but if you a cought........

I have to agree with you Alberto. I thought the quality of the plane and the construction was excellent. I have not seen a QBK in the US that was built as good.

I agree there are serious questions here. How could you remove the weight of
a Cont.O-200 in order to carry 2 people at that weight. Dousn't seem
possible...
