Hi all, I converted my Gaui X4 II to a belt drive tail. Not necessary I just prefer the belt. Hope you can follow the pictures.

First new parts needed, old ones removed.


The one major modified part is the tail drive pulley. It needs a hole drilled to place the pulley in the center of the tail boom. Use the X4 pulley.


Assemble using washers and spacers to remove up and down play


install drive pulley and belt at front end first, then pull through tail boom.


Now assemble tail rotor using one #8 S.A.E split lock washer. Bend washer flat and file to remove burr.


The tail push rod length did not change nor the gyro settings. The helicopter was noticeably quite in a hover. I haven't noticed any other differences.
Give it a try.
Michael


Forgot this picture, lock washer mod.

K.I.S.S.
