I didn't fo-grap the fuel tank. It's just an old 3-ounce steel tank from my tank drawer, revented to fit the plane. I set it up with only two vents, feed to engine and muffler pressure. To fill it, I will have to disconnect both the feed and pressure lines, thereby warding off flooding during the refueling operation. The muffler pressure is used solely to prevent loss of fuel in the unusual Slob flight antic.
I built the tank into the plane. A no-no in the stunt world, I know. But due to the low airspeed, I don't expect any trouble. Worst case: I cut the silk and fix it.
The plane comes with pre-bent flap and flipper pushrods with no means of adjustment. I dealt with this by gluing in temporary blocks to hold the bellcrank level. Then the flap was centreed by jiggering the horn position. The elevator was blocked level with popsickle sticks. It was then positioned true by sliding it fore-and-aft a little.
Notes: a hardwood block was added make the bellcrank mount double-shear. Also, some triangle stock was added to align the tail fin. After installation of the top wing, the bellcrank blocks were pulled out.
