Reminds me of my model of the Mercedes inline 6 used in the Albatross from WW1. Rotary engines are very easy in wings I can do one in 10 minutes for the basic cylinders with cooling fins. I am thinking of working on my own line of fantasy Aircraft styled in sort of the WW1 way. I have plans on using a boxer style engine configuration with the cylinders sticking out the side.
