BUILD THE FUSELAGE
❏
4. Make a 10" [254mm] long strap from the included
hook and loop material by overlapping the mating ends by
approximately 1" [25mm]. Insert the strap through the slots in
the fuel tank tray. Cut a piece of 1/4" [6mm] foam rubber (not
included) to line the fuel tank tray. Fit the neck of the fuel tank
through the hole in the fi rewall and tightly secure the tank in
place with the strap.

5. Attach a 6"-7" [152mm-178mm] piece of fuel tubing onto
each line coming from the tank.

6. If you are installing the O.S. FS81-a engine, you will need
to trim away the nose gear bearing on the top side of the engine
mount as shown. A rotary tool works well for this.

7. Using four 6-32 x 1" [25mm] machine screws, four #6 fl at
washers, four #6 lock washers, and thread locking compound,
attach the engine mount inverted to the fi rewall. Leave the
screws slightly loose. Test fi t your engine between the mount
halves. Slide the mount halves against the sides of the engine
and fi nish tightening the mount screws. Position the front of the
engine drive washer 4-7/8" [124mm] from the fi rewall.
