Guys I have a G-38 Ralph converted in a ESM Corsair. I am thinking of putting a 14oz tank in because is space reasons. I only fly about 10 minutes and land and refuel. Will 14ozs be enough??

My 40cc engine consumes 1 1/2 ounces per minute. I don't know what the G38 uses but it looks like 14 ounces will not last 10 minutes. Dan.

From my experience, it looks like you are going to need 16oz and your needles better be set correctly

That Corsair will fly full throttle 90% of the time, so not a chance.

Been running a G-38 for almost 18 years and 1.5 oz per min is a good # at full bore, so 14 oz is not going to give you 10 min flightsbut if you fly a half throtle all bets or off

Well so much for that idea. I will just have to see if I can stuff a 16 or 18oz tank in there! You guys can sure be a buzz killer! LOL JK!!! But I would rather have the truth. It always is better in the long run. Thanks guys, back to searching!!

If it is easy to install a 14oz, try it and see. Try short flights at first.

Needle settings and flying style have a lot to do with fuel consumption

Tanks sizes generally jump from 16 oz to 20 oz

Yes I just saw that! They go from 16 to 20 so no 18oz. But the 16 is the same width as the 14, 2 and 11/16. and that is all that I need. Will have to try that and see how it works! May just have to keep then short for the first flights and see where I am at on reserve! I just love when things get fun. Heavier than expected plane and smaller than expected fuel tank...keeps life interesting. 5 minute flights for the first couple to see where I am at ought to tell me....

I just finished testing a G38 with a 14oz tank on my test stand, for a club member. 10 minutes would be hard to do. I got 10 minutes but I wasnt running full throttle the whole time. Sullivan makes a lot of different shaped tanks, might be something you would squeeze in.

Yes, Sullivan has the "Flex Tank" series that will conform to a few abnormalities in the tank compartment.

I have 2 Sullivan 16 oz tanks but they were bought awhile back so maybe they are not available any more they are the slant front type, if you can find the tank size you want in some ones stuff box buy it and rebuild it. Some of the old gesers in your club or aera would most likly help you out

If length isn't the problem, a water bottle will work. You have to figure out a stopper, but it will work. Do a search for "water bottle fuel tanks".

I was once told by Sullivan that they do not recommend the "flex" tanks for gasoline. has that changed? Brian

Maybe some of you can help me with this one. If you run your plane on the ground, at wide open throttle and say it runs for 10 min, engine working as hard as it can because the plane is not moving. Would the engine use less fuel in the air because the engine (in my mind) should be working less because the plane is free to move forward. Has anyone proved or disproved this thought.
