Also about the strut, and the diagram- I would agree with what Madanna has suggested about reaming or drilling the strut,( my method also) so that the brass 5/16 dia. tube goes all the way thru with a replaceable bearing tube inside. Per your diagram; It will work- but only for a short time. Driveline vibration is a big enemy. Even with constant diligence and lubrication. the (factory) bushing wears quickly- typically caused by even slightly out of balance propellers. The resulting vibration threatens the entire driveline to loss or damage. The replaceable tube bearings last a long time and inexpensive to replace- much cheaper than a new stuffing tube, broken/damaged flex cable, new strut, etc. The importance of a well balanced propellor becomes obvious. Two other options for securing the wandering flex cable tube- Near the front opening of the inner and outer tubes. Clamping collar device- similiar to the shaft saver collar, but made to fit the area on the outer tube. Another method; also at the front of the tubes, Add a small (3mm) hole thru only the outer tube. lightly solder one tube to the other thru the hole. Prevents movement, and easily un-soldered for...
