After test fitting your engine, cowl, muffler and spinner you are ready to finalize the attachment of the power module to the fuselage.

 

There are two general ways to go about this, removeable or non-removeable.

 

If you want to be able to remove the power module for maintenance etc in the future we suggest using four button head sheet metal screws (four #8 x 5/8 Robertson screws provided). Use screws that are just long enough to go through the firewalls but not protrude into the fuel tank area. Choose the screw down points carefully to pick good solid widely distributed areas. Drill pilot holes through both firewalls being careful not to nick or hole the fuel tank.

 

Wick Pacer ZAP CA into the holes in the fuselage to toughen them up.

 

Firmly attach the power module to the fuselage using the screws.

 

If you want to permanently attach the power module to the fuselage, use Pacer 30 Minute ZEPOXY. Apply plenty of ZEPOXY to both the power module firewall and the fixed firewall. Flush the firewalls together ensuring that everything is aligned properly. Hold in place with masking tape or screws for several hours.

 

Clean away excess expoxy before it cures.
