Looks good man! Are you going to be putting more cooling vents than the one at the bottom? The openings where the real plane's exhausts are, are pretty large, and them in conjunction with the louvre at the bottom...as well as baffling, might just be enough to get air moving through and removing heat...I would hope it is, as adding more vents is going to start taking away from the 'appearance'.
I am following dilligently as I am searching for ways to get this engine in without to much hacking. By the looks of it, moving the engine back around 1.25" might just negate the need to have the valve areas cut out....its marginal..
Great work, and i am SOOOO keen to see this plane fly with that 'lump' in it.
