Post-crash inspection procedure
1. Inspect the helicopter for signs of a rotor strike on the
boom, cracks in the main rotor hub, cracks or chips in
the main blades.
2. Inspect gears
C
,
D
and
E
for stripped or missing teeth,
as well as proper fi t onto fl at spots on drive shafts.
See Diagrams 2 and 3.
3. With the helicopter powered off, inspect the gear train
for stripped gears. Hold the main rotor head still with
one hand and GENTLY rotate the tail rotor with the other
hand using light pressure. The tail should not spin freely.
4. Make visual inspection of the tail shaft for runout by
slowly rotating the drive train by hand and watching for
visible signs of a bent tail output shaft.
5. Confi rm the top pin on the tail pitch slider is not broken
or bent, and is properly seated in the slot on the tail
pitch bellcrank.
6. Inspect the tail grips for excessive play or binding.
7. Inspect the tail blades for chips, cracks or elongated
mounting hole.
Repairing the tail assembly
1. Remove the front canopy and tail assembly.
2. Loosen the screws that clamp the boom in the rear
of the frame, the tail servo mount and the tail canopy
mount. Carefully inspect the tail boom for cracks.
Remove all the parts from the broken boom.
3. Remove the tail output shaft from the tail case and
remove the tail case from the rear boom section.
4. Inspect all the bevel gears carefully and ensure the tail
drive (torque) shaft is straight. Gears
C
,
D
and
E
should
have a fl at spot in the mounting hole and should
not spin on the torque shaft. Replace any damaged
components.
See Diagram 3.
5. Fully seat the new boom in the main frame.
6. Slide the tail servo up against the frame on the boom.
7. Insert the torque shaft into the boom with the longer fl at spot to the front. Install gear B while inserting the torque
shaft.
See Diagram 1.
8. Install gear
C
onto the rear torque shaft and slide the tail case onto the rear boom section. Ensure the tail case is
fully seated on the rear boom section.
9. Install gear
D
and spacer onto the tail output shaft as you press the tail output shaft through the tail case. Ensure the
fl at spot on the tail output shaft is aligned with the D-shaped hole in the gear.
See Diagrams 3 and 4.
Access to the mechanics
The Blade Red Bull BO-105 CB 130 X features a gear driv-
en tail system that requires disassembly of the fuselage for
maintenance. In order to access the front of the tail boom
assembly, the front body pieces must be removed fi rst.
1. Remove 12 screws from the right and left side of the
canopy assembly, and remove the canopy assembly.
2. Remove 9 screws from the right and left half of the tail
assembly. Remove the tail assembly.
