helicopter main shaft.
Main Shaft
Z
c) Hang the helicopter by the tail
and use a plum line to find C.G.
on Z axle. You can use your own
methods to estimate the C.G. of
your helicopter.
*Step c) is not required in pod/boom without
camera mounted, and scale helicopter. Simply
enter value zero will be sufficient.
GPS normally mounted on tail boom, thus X
and Z could be zero, distance between GPS to
main shaft is X.
