Mount the Prop and Spinner
❏
Put the spinner backplate onto the engine or motor
shaft. Place the prop over the spinner. Align the two spinner
mounting holes with the prop as shown. Install the motor prop
washer and nuts. Tighten the prop nuts. Install the spinner
using the two machine screws provided with the spinner. You
may need to enlarge the spinner cutouts for using different
props. This can be done with either a hobby knife or a rotary
tool. Be sure to balance the spinner once the holes have
been enlarged.
Apply the Decals
1. Use scissors or a sharp hobby knife to cut the decals from
the sheet.
2. Be certain the model is clean and free from oily fi ngerprints
and dust. Prepare a dishpan or small bucket with a mixture
of liquid dish soap and warm water–about one teaspoon of
soap per gallon of water. Submerse the decal in the soap and
water and peel off the paper backing.
Note:
Even though the
decals have a “sticky-back” and are not the water transfer
type, submersing them in soap and water allows accurate
positioning and reduces air bubbles underneath.
3. Position the decal on the model where desired. Holding the
decal down, use a paper towel to wipe most of the water away.
4. Use a piece of soft balsa or something similar to squeegee
remaining water from under the decal. Apply the rest of the
decals the same way.

Install and Connect the Motor Battery

1. Remove the propeller.
IMPORTANT:
Whenever setting up
or working on an electric-powered model, always remove the
propeller in case power is accidentally provided to the motor.

2. Before you can power the radio system and set up the
controls, the motor batteries will need to be charged. Never
charge the motor batteries while they are in the model. Always
remove the motor batteries from the model while charging.
IMPORTANT:
If using multiple battery packs that are connected
with an adapter, never charge the batteries together through
the adapter. Always charge each battery pack separately.
Charge the batteries, then read the following precautions on
how to connect multiple packs for fl ying the model:
