A 6oz tank isn't going to give you better areobatic preformance. Go with the 8oz slant

Go with an 8 oz tank that will fit in the area designed for the tank. Do not forget to wrap the tank in foam to minimize/prevent foaming.

The size of your tank in dictated by two things, the size area you have to put it in and the size of the engine your running. A 6oz is great for a 25 to 40 size engine but anything bigger I would get the 8oz or even a 10oz. I run 10oz in my old trainers with OS 46fx and at half throttle it will fly for over 20 minutes.

An 8 ounce tank for a 40 to 46 size motor. Look at the Sullivan Flexi tank, this is softer plastic that can squeeze a little, making it easier to fit into the nose. If you drill a 3/4 or 7/8 inch hole in the firewall for the tank stopper to fit into, than it should be a Sullivan RST style flexi tank. Drat, it was so long ago i just don't remember the exact installation.
