Assemble H0082-S in the tube:
Pre-assemble the two boom spacers H0082-S with the M3x20
socket set screw.
Insert into the boom tube completely done up.
Center the holes, then unscrew until there is contact with the walls
Lock everything with the adhesive.
Assemble H0040-S in the boom
Before assembling the two parts in the boom we suggest
tightening
the M2.5 screws into the two plastic parts to pre-
thread them. In this way when you will assemble the tail
servo it will be easier to tighten the screws into the plastic
parts. Check the tail servo can fit, if necessary carefully sand
the hole.
