Page 15, step 2 of the manual should read "Drill a pilot hole through
each of the marks on the template. Remove the template and then
drill a 13/64" (5.2mm) clearance hole through the firewall on each
of the four pilot holes you drilled.
Check the servo tray and formers before flying. If needed, apply
CA glue to any loose joints.

COMMENTS
