1/3 Scale Sopwith Pup Question

       Remove this ad - become a site supporter!
My 3 year Sopwith Pup project is near completion and I am beginning to wonder if I made an error in mounting the engine. I mounted a G62 vertically as there were no suggestions from Balsa USA which way it should go. After I mounted the cowl I noticed that the air outlet opening is at the bottom. Am I going to have a cooling problem? Will enough air circulate through the cowl to cool the engine in this position. I can invert the engine but it will cause a lot of work as fuel tank and servos have to be moved. Also I am hearing from some people that a gas engine like to be upside down? This does not make sense to me as IMAC guys spend as much time upside down as sideways??

Cliff the gas engine does not care how its mounted. If you invert the engine you will not have to move the tank as the carb has a needle and seat to control the fuel flow to the engine. You would have to change the throttle cable though. If you are putting a dummy radial in the nose it would be simple to make a baffle that would direct the air up and around the engine cylinder then down and out the bottom.
