Just got the pull pull system in for the tailwheel and the tubing to connect the air cylinder Once I get that in I can sheet the bottom of the fuselage. I can then mount the engine and build the front of the fuselage, I already have the aluminum stand offs to mount the RCV engine 1 1/2 inches from the firewall to get the engine prop thrust plate 6 1//4 inches from the firewall so I can build the fuselage around the engine. I have the factory backing mounting plate so I am going to rethread it to match the standoffs then mount the plate on the back of the firewall then screw the screws through it and through the firewall and then screw the standoffs onto the screws on the front side of the firewall.

Cold outside so just worked a little on it shop is cold. assembled the motormount for the RCV using 1 1/2 in standoffs so I will have 6 i/4 inches between rthe firewall and the thrust plate. Used the plate supplied with the engine for the backing plate and had to drill the engine and the plate to accept the 10x32 screws the standoffs require.

It isnt a rotary design it is actually a standard 4 stroke design with a rotary valve. The piston and crankshaft are horozontal and drive a standard crankshaft that drives the rotary valve which doubles as the cylinder the piston operates in the cylinder and the rotery valve also doubles as the properller shaft and because the crank pinion gear to the cylinder has a 2 to 1 rario the prop operates at 1/2 the speed of the crank so you can turn a bigger prop. neat uh. here is a link to RCV http://www.rcvengines.com/rcv_modelhome.htm
