I started looking at the work you have done on your canopy...that is an awesome job!! I had not planned on doing a functional canopy but yours looks so nice I believe that I will use your method and do the extra work. Thanks for sharing that with me. I agree with you on the cooling thing with the La7. Everything I have read about the full scale claimed that the cockpit was extremely hot for the pilot that flew it, even in extremely cold temperatures. The oil cooler helped keep the engine cooled down but like you, I think the cowl kept a lot of the heat in and probably was the cause of the overheated cockpit. Those poor guys!!
