I am assembling a Ziroli/Midwest kit of a He-162 that was manufactured about 1978. The engine is a K&B 7.5 DF engine from around 1979, and is new in the box with all the papers and accessories. The fan is an Axiflo RK-40. It is also brand new in the box with everything still sealed up.

Before I open up the Fan kit for construction, is it worth more as a collector? When I say kit, this thing is really a kit. You build everything from the shroud to the mounts. Also, Is the K&B DF engine worth anything more than usual?

I intend to finish the He-162, but wonder if I might get a newer powerplant without spending more money.
