Great Planes Super Stearman 1.20 ARF - GPMA1350 - Manual (Page 25)

Our prototype model required the addition of nose weight.
This is not uncommon for short-coupled airplanes such as
the Stearman. We have included a location for you to easily
add the weight that most likely will be needed.
❏
1. Locate the plywood parts that make up the box. Glue the
box together as shown. The box will be exposed to engine
vibration so be sure you have good glue joints.
❏
2. Glue the two 1/8" x 1/4" x 3-1/4" [3 x 6 x 83mm] plywood
sticks together. Then glue them to the front of the box.
❏
3. Fit the box cover to the box. Drill a 1/16" [1.6mm] hole
at the locations shown. Install and then remove a #2 x 3/8"
[10mm] sheet metal screw into each hole. Remove the
cover, and then apply a couple of drops of thin CA into the
holes in the box to harden the threads.
❏
4. Refering to the photo on the following page, locate two 1/2"
x 11/16" x 2-1/2" [13 x 18 x 64mm] hardwood blocks. Position
one of the blocks on the bottom of the engine mount. The block
should be resting against the engine mount rail and the socket
head cap screw that holds the engine mount to the firewall. You
will see that the block cannot sit on the rail because one of the
engine mount bolts is extending through the rail. Mark the
location of this screw on the block. Where you have marked the
block, cut away enough of the wood to provide clearance for the
screw, allowing the block to rest against the rail. Repeat this for
the remaining block.
