Krener,
Some of the realistic reasons for going electric in the .46 to .90 size planes are, the ease of operation
no deadsticks , no mess. The ease of cleanup. Noise level. Linear throttle response.

Once you get into the 1.20 and larger engines the cost savings becomes more apparent. I run an
OS 1.60 in my 2m pattern plane, my 16 oz tank last for 12 minutes. I burn a case of fuel in a weekend
if I fly both days and I like to go to the field after work at least 1 day a week. Thats 5 gallons of fuel a
week. at $15-20 a gallon I will soon see the cost savings in a $400 lipo pack that will give me 300 flights.
I can't fly gas in pattern as right now no-one makes an engine that will meet the weight and sound
requirements for competition. So for me it's cases of fuel or electric.

in the smaller planes it seems more of a preference between nitro or electric, I will fly both.
