Click to ENLARGE DANGER: When you get the unit, Jack stacks 2 of the microswitches on the down mount. One has no wire connections. This is in case you want to use the free switch to wire as a per plans gear up warning when the throttle is retarded. That sounds funny. I took the switch off and used the 2 screws to re-mount the switch. I threw the panel gear switch to down and when the down microswitch was supposed to pop open, it stayed shut. THE REASON is when the switch is mounted directly to the the mounting flange, the switch arm CAN stay put due to friction from touching the flange. Luckily, I had my finger on the control switch and was looking at the microswitch so I caught it. I would recommend you do the same until everything is just right and tight. I added a spacer between the down swich and the mount. I almost had another CRASH with the up mount side. I slid the up micro switch to the furthest point down so I could creep up on the gear uppermost travel. WELL, the wheel on the microswitch did not release when it was supposed to because when the micro is on the lowest point, there is a radius machined into the retract unit. In fact, you can see it in the photo. The wheel caught on that. My quick finger caught that mishap before it happened too. Must be all those years of playing video games as a kid. Bottom
line, be VERY careful when making your initial adjustments because there's a
LARGE gear reduction and things can be ripped apart in a flash. I mounted the switch panel temporarily because I will be raising and lowering the nose several times during construction, as well as to impress visitors. :) Here is the wiring diagram you get when you use the auto extension system. What the heck IS all this!? --- It was intimidating at first, but as with everything else on this airplane, you stare at it long enough, and you figure it out. |
