This is just a start! To share your tank & engine information, email me at email@example.com .
RCS 1.40 gas single, use 8-12oz tank.
BME 2.7, 44cc gas engine, use 16oz tank. (This applies to most 40-45cc gassers.)

I fly a Radiocraft Extra 330 with a BME 102 and use a 24oz. tank. With good throttle control I easily get 15 min. flights at 4300ft. Mike, SA list
I use a 32oz tank to give a 14.5 min flight with the BME 100 engine. I have 1/4 of the tank left after the flight. ( In case I botch a couple landings or someone crashes on the runway, I won't run out.) Don, SA list
I'm getting 15 minute flight times with a DA100 and a Mejzlick 28x10. The
tank is a 32 oz. Du-Bro. My Flying style is IMAC which means Smooth throttle transitions
and low to high throttle positions. NOT an on off switch. That leaves about 1/4
to 1/3 of fuel left in the tank. If I fly for 10 minutes pattern and 5 minutes
hard core 3D torque rolling and lots of vertical full throttle climbs, that 1/3
left in the
tank drops to about 1/8th. Jeremy, SA list
Originally had a 24 oz with my DA100. That provided two sportsman sequences and a deadstick on downwind. With the NATS only a day away, we found a 32 oz. to put in. Now that it's broken in, a 24 oz would be fine I'm sure, but I needed the extra during break in. With the 32 oz, I got 20 min. today with a lot of wind and high power settings! Baron, SA list
DA 100: Sullivan 32 Oz. I can fly the advanced sequence 3 times with
fuel to spare. Francis, SA list
