Hi -
I want to get the longest time possible in the air. My trainer has an os 61 and I want to get a 15 to 20 minutes flight - how big of a tank should I put in it?
where can I find info of "burned fuel per minute" or something of that nature. YES, I KNOW that it depends on how fast/slow you're flying, etc etc, but I am just looking for ball park figures
thanks
Take a look at
http://jettengineering.com/ and punch up his fuel tanks, specifically the Bladder Tanks. He has 12 0z. bladder tanks available. I have not tried those yet, but I have some to try. Using 40 to 45 engines with 6 oz. tanks I easily go 12 minutes where that was always about 8 minutes before bladder tanks.
IMO, I think it is bacause the bladder tank allows for a more precise fuel setting without going overly lean. The only problem - just my problem - is that it seems that the bladder tank is not all that good for repeated touch and go practice near the end of the fuel supply like about the last several minutes. I think that may just be the mechanics of the system.
Other than that and the need to perform precise fueling procedures using a syringe, they provide the most precise fuel feed going!
