Somebody brought this cutaway engine to the Reno Air Races.
Just thought you might like to see what a air cooled, radial motor looks like from the inside.
The front of the motor is to the right, where the propellor connects.
The aft section, blue part, is the blower, 2 stages.
The black device on the top is the carburator.
If anyone knows more about these motors, please add whatever you'd like.
Here's the first of five photos, just push the "next image" button located in the upper right hand corner of the photo.
