the temp gauge shows only the temp of one cylinder, you have just to select wich one

the key is, as with all radials in game in the moment, to keep the temp between 200and250. lower or higher is 'bad'
and , it has no automatic mixture, the higher you get, you have to lean the mixture manually step by step.
and you have trimm for all 3 axis.
its and interesting plane to fly, just not to fight in it
