Excelleron 90 and OS 1.08

[Eddie Batchelor]

I had a NIB OS108 that I thought about using on my Explorer/Excelleron.
After looking at the weight & power output specs, I sold it.
Now after you compensate for the extra 7 ounces on the nose with a bunch
more weight on the tail, how well is it gonna fly ?? - good question.
specs copied off towers site:

Weight: 750g (26.5 oz)    31.4 oz w/muffler
          Max Output: 3.0 BHP at 16,000 RPM

Os91
Weight: 550g (19.42oz)    24.3 oz w/muffler
          Horsepower:        2.8 BHP at 15,000 RPM
          Suggested Prop Sizes: 13X8, 13X10, 14X6, 14X8, 14X10, 15X6, 15X8,
