Hi Jon, I have a new UL Power cowling, unwanted, and it looks nice. But don't get excited, I'm building a CruZer in South Australia! I was originally going for a UL i350, but switched to a Viking 130. I shipped a full plane kit and the UL cowl & engine mount as one to save on freight. As an exercise, I could take it's re-packaged dimensions off to the post office(or similar) and just enquire as to what it would cost to ship. It would be interesting. As it is, I may have to re-model the front bit of my Viking cowl, so your thread will be worth following. My email jheatheraus at
