I am building a one tenth scale hydro from Gary Finlay plans. Just received all hardware and motor, etc., from Offshore Electrics on their recommendation, for this boat.
Have had no experience with flex drive, with no one in close proximity to ask.
Speed Master 21 Hydro Strut
OSE.187 cable complete
1/4 inch diameter brass tubing for stuffing tube
Question: Do you insert stuffing tube into strut, or leave it a short distance away? The bushing is very loose in the strut, and fits inside the stuffing tube. What retains the bushing and the strut?

Any offers of help is much appreciated.
