Bob, I just finished assembling mine as a winter bang around plane too. I have a YS 120 going in mine as I've seen one of these fly with a OS and Magnum 120 4S and it didn't have the pull through the top of manuvers. I've seen Tommy's fly with the YS110 and it was awesome so the 120 should do fine. I used all the stock hardware and including the hinges but I painted the inside canopy with Testors plastic model spray paint and it came out real slick. I don't like clear canopies.
