Zeque YS DZ 1.60/1.70 build

Regarding pushrod installation, my answer applies to all installations not only the Focus II.

Jon,

In order to measure, EASILY align and install my elevator pushrod solution, I cut (2) holes in the bottom of the fuselage. Each 1 1/2" hole was cut with a forstener bit after a slightly larger hole was cut through the covering. The pushrod was installed, measurements of the "center" of each hole at each bulkhead (2) in the case of the Focus II, and then the support material was cut and fit. The pieces were not installed UNTIL the stab and elevators were installed BUT the pushrod was put in the fuselage with the formers "loose" prior to the stab being installed. I also lubricate the rear pushrod capture with lithium grease.

To this point, the elevator is pushed into the rear capture point, the supports are free and the servo tray is floating in the fuselage as well. Connect the rear of the pushrod and adjust the clevis' to center the servo end of the pushrod in the fuselage. Move the servo tray and the various supports until the pushrod moves very freely. In my case, this took a minute because the foam support bulkheads were accurately cut and fit well. Tack glue the servo tray end if satisfied. I used Zap a Dap a Goo to attach my foam (stiff slippery stuff) formers.

The final product is very light, moves perfectly smoothly and optimizes equal elevator movement with little to no slop or "rotational" deviation- perfect for a Focus or built up construction. My skills and patience required me to cut access holes which were filled in with a couple circles of covering. Whatever method you chose, you must execute it for it to work properly, so chose a method consistent with your skills.

Ideally, the kit would have had the pushrod made and installed...or I should have just paid Troy (Mr. DEPS) Newman to do the DEPS before it was shipped. As I have previously stated, I will strain my tiny brain reviewing the options.
