PA 40 lite

I was reading in another post about smaller aircraft. Well this is the direction I have chosen. Just recived a new PA 40 lite and after weighing both drive components I will save about 6 oz. Also sprung for the Mag head.I am going to build a new design of around 640 SQ. Should come in no more than 45 oz. With the .012 solid lines should have more response.

Also at this time I would like to Thank Randy Smith for the fast service and shipping.

One thing I wasn't very clear about (I'm not clear about a lot of things, I suppose. My critics are legion), How does the PA 40 Lite compare to the standard (regular, non-Lite) version of the PA 40? Does it run any different? Is there any difference other than weight? Size? Length? Other stuff?

As I have never had a regular PA 40 I couldn't say for sure. Maybe somone else has had both. All i can say for sure is the one I saw fly a the WC from Canada ran great! The same setup as you see in the photo. Muffler instead of pipe. Pulled like a bear.

Randy is the one to give you all of the details, but I can add what I know. The 40 Ultra Lite is a smaller case. It is a smaller stroke and larger bore than the older (the one we are more familiar with) 40 PA engine. For smaller airplanes, using smaller props at a higher rpm, it will provide more power (and less weight) than the "familiar" 40 (which Randy actually calls the "Lite", as opposed to the "Ultra Lite".) When turning larger props, however, the older version (bigger case) will provide more torque. So, for bigger props, use the large case. For smaller props, use the new small case engine which will then provide more power and less weight for the smaller planes.
