Repairing the Gear Unit
24
To replace the fuse: 1. Turn off all switches. 2. Remove the battery
pack from the airplane. Be careful. The area inside of the battery box
may be hot from the battery pack releasing energy during fl ight.
3. Using sturdy tweezers or needle nose pliers, remove the fuse
(located in the front of the battery compartment). 4. Gently, but fi rmly,
press the replacement fuse (included with your Air Strike
®
) into place.
5. Additional fuses are available from your local hobby store or
directly from Megatech.
If the propeller on your aircraft is wobbling or vibrating excessively
(as in
Figure 23
) or you notice a loud grinding noise coming from the
gearbox, it usually means that the gear shaft is bent and needs to be
replaced (an extra is included with your Air Strike
®
).
Follow
Figure 24
and disassemble the front of the aircraft and
replace the gear shaft.
Installing a New Propeller
When it is time to replace the propeller, be very careful to install the
new propeller in the proper direction. If, after replacing the
propeller, your Air Strike
®
seems as though there is not enough
power to fl y, you’ve probably just installed your propeller backwards.
When looking at the propeller hub (center), you’ll note that one side
has a hexagon shape, and the other side has a perfectly round hole.
The side with the hexagon
goes against the spinner
backplate (toward the tail
of the aircraft).The side
with the round hole faces in
front of the aircraft. You
tighten the prop nut against
this side of the propeller.
