Stock tank, which looks like 16oz. Probably getting about 8 minutes, but not sure. If you ask me again in a week or so I'll have a better idea as I get this pump working properly and engine tuned right.

It's a perfect combo - easy to use/run/tune, lots of power, not too heavy. I only needed 1/8oz on the tail (servos mounted in rear). There's a VII thread in the pattern forum that will tell you everything you need to know. If you're serious about this plane, you will be disappointed (according to others) with a 90 two stroke or a 120 four stroke, so the most common setups are a 120AX and a YS 110.
