This is one of those on again off again projects that I've been working on for some time. It's loosely based on the Gnome type N nine cylinder. I originally intended to actually use it on a radio controlled quarter scale Nieuport 28, so I thought it would be wise to actually build two engines at the same time, just in case. Besides, most of the work in parts like this is in set-up so an extra set is actually very little extra work. So far I've completed the crankshaft, front and rear crankcase covers, cams, most of the parts associated with spark timing and the cylinder liners. I also got a good start on the finned part of the cylinders and I made a somewhat lame first attempt at casting the crankcase. I still need to make the master and slave connecting rods, pistons, re-design and build the valve train assembly (I don't care for the original design), and recast the crankcase. I also need to make some spark plugs at some point.
