912 Smoke system
I am looking for experience/ advice on where to fit smoke injectors for optimum temperature on Rotax 912Is?
The exhaust gas must be hot enough to vaporise the smoke oil, but not too hot to burn
The simple choices would appear to be in the exhaust pipe(s) before the muffler, or in the exhaust elbow after the muffler?
Does anybody have any real life experience of where to position the injectors?
