DRILLING PROPELLER:
The most reliable, consistent and safe way to drill the prop-bolts hole in the propeller is the use
the GS R/C – DLA PROP HOLE DRILL GUIDE. Any other method is not recommended and can
produce results that are unpredictable and potentially dangerous.
1. Place the GS R/C-DLA Prop drill guide into the propeller’s center hole. Often, propellers
have the center or crankshaft hole pre-drilled to ten (10) mm diameter. If the prop’s
center hole is not ten (10) mm, it must be drilled to 10 mm. Use only a self-centering 10
mm drill bit to produce the center hole of the proper diameter.
a. Drill the first prop-bolt hole using a drill press.
b. Use a wood back up plate under the propeller to help prevent splintering the
backside of the prop-hub.
2. Place the alignment pin in the hole just drilled, passing it through the Drill-Guide and into
the prop. This secures the Drill-Guide.
3. Drill remaining holes.
DRILLING SPINNER BACK-PLATE:
Most spinner back-plates are not specific as to the angular position of the back-plate relative to
the spinner cone and thus the prop-hole locations in the back-plate are not critical. Some back-
plates are solid and some have multiple holes in them for lightening. In the case of the ones with
lightening holes, check to see if the existing holes will align with those required for the prop bolts.
Otherwise, use either the PROP-BOLT DRILL BIT GUIDE or the engines front prop washer to
mark the hole locations and drill with at least one to two (1 -2) millimeter clearance all around.
When mounting the spinner, be sure the spinner back-plate holes are not in contact with the prop
bolts.
ENGINE STARTING:
General:
Sometimes, when the engines have been dormant for a period of time, such as sitting in the
vendor’s warehouse, winter storage, etc., the carburetor gaskets can dry-out and be just a bit less
