Hello Ron, i do intend to put baffles in the cowl to direct airflow,but im unsure what material to use, maybe some lithoplate? Fuselage will be covered in solertex as the rest of the model, pictures arn,t brilliant.Just in the process of doing a little detail in cockpit ,not too much though, a few instruments, pilot ect.Hopeing to complete and have a test flight before winter really sets in.Ive used heavy duty snakes for control surfaces,4-40 SIZE,what did you use? Cheers, Frank
