Aeroplane - rotary engine

with thanks to Richard Pearse, Waitohi, New Zealand, March 31, 1902

The rotary engine was one of those things that just worked! Once I knew the systematics I pulled out my bits and built it. Perhaps I was feeling inspired, but everything just fitted together as it should. The instructions for the engine don't use any piece that is currently unavailable, but if you want it to run smoothly you will need to use the old piston head pieces that were available in sets such as the original super car. Sure the new pistons are nice and compact, but they don't have the versatility of thee old chunky type. Have a look at bricklink.com if you're desperate for some.
The LDRAW CAD for the rotary engine comes in two parts. The shaft of the engine - which has the pistons etc attached, and the housing or cowling of the engine. It's a multi-part model so both files will need to be in the same directory for it to work in your LDRAW software.
I've also got PDFs of multi-step instructions for the engine with each step detailing the parts required.
