Engine Performance Page

Impressive eh? Well not really, its just a place for some real world data
from our personal experience with our engines.


The prop data posted here is made through highly unscientific means.
The days of testing varied in temperature, humidity and pressure, and at 4100'
Although checked with 2 different tachs, your mileage may vary.

Zenoah G-23 -  Bennett muffler                     3.5 lbs with muffler and prop
     G-23 after about 1 gal - 


Brison 2.4 - Bennet muffler                             3.25 lbs with muffler, ignition battery and no prop


My Overall impression for 4 strokes and sport flying, the plastic Scimitar props
and for gas, the wood Scimitar are hard to beat. They may not tach as high as APCs
but they seem to perform as well or better in some cases. You can get better props,
but not much cheaper, and they perform well.

I will add data as time and circumstances permit.
