Guys, what is the cheapest yet reliable retracts for this warbird? I just got a Modeltech P-47 due to low cost and high flyablilty of it, and still cannot get the Hellcat out of my head! It has always been my favorite WWII bird. And will the OS 120 pumped be plenty of power or just adequate? You guys have beautiful Hellcats in this thread!!! Thanks. Jon
