Well I was able to do one thing to my model that I haven't seen very many others do with thier models and that is making my air cooler flaps work on the cowels And I mean when the throttel is closed then the flaps are wide open for max aircool and at full throttel the flaps are closed all the way. At half throttle they are only opend half way. Now I have never seen any other models with working air cooler flaps and thats even a few of the big boys. I did read somewhere that someone was trying to make thiers work but off of a heat sencer probably be better if they just tryed to make them work first. And I have just done that. I also made a set of mechanical brakes for my B-25 and was told that I could never get them to evenly but I'm not worried about that cause if I run out of runway then I would want to have the plane turn one way or the other. Instead of going off into the ruff grass and breaking the landing gear or something else. Just my thought on the subject. You people keep up the work on the models of your choise and do the best you all can do.
