After completing the cutting and drilling of your power module firewall, review Pictures 14D and 15A in the Easy 3D Assembly and Operations Manual. 

 

Use Template B.  This template is used to position the T-beam engine mounts and subsequently drill the T-beam mounting holes in the power module firewall. This template is for the VMAX 46PRO, 52PRO and similar engines that mount on T-beams with approximately 1.53 in spacing (38mm) between the lug portion of the beams. If your engine mounting lugs require T-beam spacing that cannot work with 38mm spacing you can modify the template by cutting the template vertically along the center line and increasing or decreasing the distance between the resultant template halves to reflect the size of your engine.

 

The Template B sheet contains a expanded depiction of a typical T-beam mount and engine installation. Use scissors to cut out just the retangle bounded by the T-beam mounts as shown in Template B. Consult the pictures before cutting. You want to end up with Template B looking like the lighter (whiter) shaded paper shown in the pictures below.

 

Position the center point of Template B over the center line intersection point of Template A on the power module firewall. Rotate Template B 207 degrees counter clockwise from horizontal until the engine lug lines on Template B align with the corresponding diagonal lines (Z1 to Z1 and Z2 to Z2) shown on Template A attached earlier to the firewall. Ensure the center point of Template B remains centered over the fuel tank outlet hole while the lug line remains aligned diagonally. Secure Template B in this position using adhesive from a glue stick.    

 

Use a scroll saw to cut the fuel tank outlet clearance hole in the plywood as shown on the template. 

 

Center punch the four holes marked B. Drill all three center punch locations with a 5/32 inch drill. You can use a 3/16" drill if you wish to provide a bit looser tolerance. After drilling the holes, turn the firewall over and counter sink these four holes from the back of the wirewall using a 27/64 in. drill. Counter sink the holes to a depth of the thickness of a washer (approx 1-1.5mm) at the perimeter of the counter sunk holes.  

 

If you wish to seal the power module firewall, now is the time to do it. This is not mandatory but makes for a neater more professional looking finish. Remove the templates and wipe away any adhesive residue. Blow off any dust. Coat all surfaces with Pacer Finishing Resin. Set aside to cure.
