I have an unbuilt Dragon Lady ARC which I picked up on the internet a few months ago. The kit comes with a glass cowl and wheel pants - guess yours was removed from the box before you purchased it. The ARF cowl should fit - as far as I know the planes are the same, but Global Hobby can confirm that. We have 3 guys in our club that fly the ARC version, and all are sweet flyers.
Here's a good construction article - http://www.bumpygreen.co.uk/Reviews/...Dragonlady.php
