Glow vs Gas Operation Cost Comparison for 60-120 app

[granspeed]

So I was researching for a new engine on my 60-90 plane and ended up making a generic operation cost calculation for the similar capacity engines and thought I might share with everyone just for Shi*t's and Giggles.

I compared the below listed engines on the attached file.

Benchmark Glow Engine

OS61FX
OS91FX
Saito FA115
Saito FA125

Comparison Gas Engine
Saito FG-20
Evolution 26GX
Zenoah G-20

Here was the result (based on running a 450cc tank $22/gal for Glow and $4/gal for Gas)
Saito FG20
vs OS61 never before 100 flights
vs OS91 never before 100 flights
vs FA115 after 97 flights
vs FA125 after 83 flights


Evolution GX 20
vs OS61 never before 100 flights
vs OS91 never before 100 flights
vs FA115 after 60 flights
vs FA125 after 46 flights

Zenoah G-20
vs OS61 after 94 flights
vs OS91 after 69 flights
vs FA115 after 9 flights
vs FA125 from the 1st flight

Some of the ultra low priced gas engines out there were not included like RCS SV engines. Those engines go below $200 so it may be worth doing more research!!

Considering the price of Glow Fuel, transition from glow to gas on smaller size plane might not be a bad idea after all... If they start making them lighter, it would seem to be the way to go.

Don't forget the cost of paper towels and glow plugs in your calculations for the glow planes.
