Guys, I have a DL50 new in the box for a Extra 330L that is just like the PAU version (not available anymore) but I got it from AKM a couple years ago. Plane is still unfinished too. I am getting the bug to finish it, and am wondering now if the new DLE55 is better enough over the DL50 to warrant getting it, and selling the DL50, or should I just stick with the DL50. This is what happens when I buy something and don't finish it right away...things get out of date. Your input from guys who know both engines from personal experience is appreciated. THANKS. Jon
