RE: GMS Engine problem
Been having the same problem with my GMS 61. Get the needle valve set and the engines does fine on the grond, but once in the air it dies on me after about 2 laps of the air field. I have it on a GP stuka, so it is a cowled engine, but tomorrow I am gonna try flying without the cowl to see if it is a overheating issue or not. Any other suggestions?
