A few design questions

[Entropy455]

I counted 7.5 turns in 18 seconds, wich is equal to about 25 rpm.

I took a video of my Simplicity this weekend...it was less than 300 but no were NEAR 25.....Holy C)(*&$(* !

You have to admit though....that is just NOT normal though!.....

I got the record on Sabino that runs a 75 HP compound turning a 4 foot diameter 5 foot pitch prop

13 rpm

The prop helps alot...and it is a steam engine...so I'd say it has an unfair advantage over an IC engine...
