The tail boom can only fit one way on the X400. The slot in the boom goes
into the main frames and stops the boom from rotating. The hole in the
other end of the boom locates on a small peg inside the gearbox and stops
rotation of the tail gear box. I used the long tail pushrod to pull the
tail belt through the boom. The boom is inserted into the main frames and
then the belt is twisted onto the main frames drive pulley. The pinch bolts
on the mainframe can then be tightened to clamp the boom in place.The belt
should be run loose such that when it is pushed it can nearly touch the
other side of the belt. The manual covers this in nice clear detail The
white pins should be CA'd onto the carbon pushrods. |
