15. Cut a piece of 1/4" [6.4mm] foam rubber to fi t under
the ignition module. Place the module onto the fi rewall box.
On each side of the ignition module drill a 1/16" [1.6mm]
hole. Locate a 1/4" x 1/4" x 1/4" [6.4 x 6.4 x 6.4mm] hardwood
block and glue it to the fi rewall box under the hole you drilled.
Drill a 1/16" [1.6mm] hole through the hole you drilled and
into the block. Screw a hook into each off the holes you
just drilled. Secure the ignition module with a couple of #64
rubber bands (not included).

16. Repeat step 15 for the ignition battery.

17. You need to decide where you wish to put the switch and
charge jack for the ignition module. Though it is a bit tedious
we found that there was room at the front of the fuselage.
We recommend that you use a heavy-duty switch such as
the Futaba heavy-duty charge switch (FUTM4385) and the
Ernst charge receptacle (ERNM3001). When determining a
location for the switch make sure you keep it as close to the
engine as possible to prevent any possible interference with
your radio system.
Install the Fuel Tank
For the installation of the fuel tank you will need approximately
60" [1524mm] of tygon fuel tubing (not included). Be sure you
have this before proceeding with the next set of instructions.
❏
1. Solder a fuel line barb onto one end of each of the
three tubes.
❏
2. Assemble the stopper, tubes and metal plates. Solder
another fuel line barb onto the ends of the short tubes. Bend
the brass vent/overfl ow tube upward so it will be at the top
of the tank.
