Luke you know what I'm talking about...
a gallon of Morgan FAI fuel cost $10...$11
a gallon of 93 octane Gas Fuel cost $1.70 +-

Moki? have been there for long time....I sold all the big nitro engines: Mokies 1.8 and 2.1, OS BGX 2.1, Super Tigre 3200 some time ago.

Moki is the best nitro engine in it's class but still drinks lots of fuel to fly only 10 maybe 12 minutes, I can make my 2 Midwest Caps 16 or 17 lbs with any good and light 50cc Gas engine (ZDZ-50, BME-50, DA-50), can have better performance, fly more time and the most important thing, $1.70 a gallon on my next Shell gas station.
