IMHO this is a major breakthrough in cutting the work required
to install a liquid cooled engine. This has far reaching
implications for the acceptance of the rotary.

A rad installation like this could take as little as two hours.
The stock oil cooler could be added along side the rad.

The the interior of the cowl is opened up with far more room to
work on the engine and accommodate mufflers under the engine.

All you need add to this illustration is side plates.

The angle of the rad can be adjusted up and down to decrease
or increase the cooling effect.

Will work for pusher and tractor.


This is a brilliant idea on whoever thought it up.
Good thinking outside of the box. Literally :)
Brilliant! brilliant! Brilliant!

IMHO this will become the cooling system of choice.

  This would also appear to do away with the need for cowl flaps - can use
cowl flap lever to adjust radiator angle.  Perhaps just have a rod connected
to the front of the radiator, poking up through the floor board, so when you
push the throttle in you can also "step on it" (the rod)  further lowering
the radiator for more cooling {:>).

Certainly looks interesting and simple, who will be the first to try it ??

Ed Anderson

Good idea Ed. 

BTW I am really jazzed on this rad location. This removes many of the
objections to liquid cooling systems. Simple cheap and easy to make and install.
Again: The rad IS the scoop, the duct and the diffuser.
