Hi T/B

Idon't know what the fuel consumption is on your engine, but both of my G-62 burn about 1 1/2 oz's per min at full throtle, so depending on how long you like to fly at a time would determine fuel needed ie: say 2 oz's per minuit and you like to stay in the air 10 min a 24 oz tank would only give one go around if you mist a landing.
I am using 16 oz tanks and that works for me at about 7/8 min in the air.
