3. Once you have verified everything fits properly, mix up
some 30-minute epoxy and apply it to the exposed wood on
the root of the blade. Install the top and bottom reinforcements
as shown above. Double check your work to verify the
reinforcements are installed properly. Install and tighten the
two 2.6mm screws into the reinforcements as shown.
❏
4. Use a paper towel dampened with isopropyl alcohol to
remove the excess glue from the blade. Before the epoxy sets,
install the blades into the grips to clamp the reinforcements
down onto the blade. Once the epoxy has set, you can proceed
to the next step.
❏
5. Using the 4mm bolts and nylon lock nuts, install the
blades into the grips as shown.
BLADE BALANCING
Note: All main blades must be balanced before use. We
recommend using the Heli-Max Blade Balancer (HMXE4855).
❏
1. Apply the two colored stripe decals to the tips of your
main rotor blades (for use in blade tracking later on).
❏
2. Prepare the balancer for use by rotating the brass
adjustment dial until the bubble in the vial indicates level. Make
sure that the blade balancer does not move during this process.
❏
3. Place one blade onto the balancer with the leading
edge against the side with the level. Shift the blade on the
balancer until the bubble indicates level. The middle of the
black balancing tray is now at the C.G. of this blade. Mark
this position on the blade with a felt tip pen.
❏
4. Line up the ends of both blades. Transfer the mark you
made on the first blade to the second blade.
