Yes to me there was quite abit of diferents , the xl seems to me to be alot more slippery though the air .No were as dragy as the slats , the xl handles wind gust alot better, in the old one it was quite scary when you got a sudden gust.The xl cruise is a bit better , not alot.Thats why i think if you want a fast plane look else were ,they are great for what they are designed for.The best thing with the xl was more leg room , im 6f 1inch so the leg room was great compared to the old one.A bit less vision over the dash in the xl but not to bad.Just great little plane Mark.
