A friend recently bought a Savannah and I have to say it is one of the nicest handling aircraft I have flown.
It has a Rotax 914 and I assume a factory air box. Very large and professionally built.
An issue we have is the air box temperature is quite hot, 20 degrees above ambient.
The baffles are working in fact I disconnected the hose coming from the muffler.
The cool air inlet has a scat hose running to just behind the prop.
There has to be some power loss by running air to the carbs at 40c.
Any suggestions.
