I'll use a Robart large tank for the mains and doors, and two medium tanks (not sure the brand but about the size of a medium Robart). One for the Brakes & Airbrake, and the other for the canopy. I believe the large can will fit in the rear compartment, kind of to the side of the turbine. The two smaller tanks can fit underneath the fuel tanks. The Xicoy would be nice, but I'm using what I have.
