Hey, good thing about our R/C planes is that the tank is almost always removable.

Stick the 10oz in there and go fly it. If you decide it's too small (which I'd bet against) you can put a bigger one in.

The most excellent thing about our hobby is that it ALWAYS provides us with strong reasons to buy our next model. If you discover that the 10oz is either too small or too large, what is your only alternative? To buy a "proper size" tank. And then what will you have sitting there??? A TANK THAT NEEDS ANOTHER MODEL AIRPLANE to keep you from wasting money on that now unused tank. TAA DAA !!!!!!

Ain't this an awesome hobby !!!!
