我每次整木機都會遇到一個問題: Hinge好硬, 當行程去到盡時, Servo好大機會Dee Dee聲...

依家10g樓下嘅Servos, 大部份Torque都唔會好大, 所以如果Hinge硬, 會增加Servo嘅負擔...

以下係喺"On the Flightline"見到嘅Tips, 可以作為參考.

8 Tips to install CA hinges
When gluing CA hinges into the slots for a model's control surfaces, there are a few things to do to make the job neater and easier.

1. Use a sharp hobby blade and remove a thin sliver from above and below the horizontal slot to make a very shallow V. This helps clear covering material away from the slot and exposes some of the wood around the slot.


2. Use a small 1/6-inch drill and drill a hole in the center of each slot. This will help wich glue into the hinge cavity.


3. Mark the middle of the hinges with a pencil so you can install them equally into the control surface and the supporting surface.


4. Use thin CA, not medium or thick CA. Thin CA will wick more easily into the hinge slot.


5. Place the hinges into the movable surfaces first and apply two or three drops of adhesive to each side of the hinge. Wipe away excess glue with a paper towel.


6. Slide the hinges into the matching slots and center the control surface so it is in the proper position. Be sure there is clearance on either side of the surface so the hinge does not bind.


7. Apply two or three drops on the hinges to glue them into place. Use a paper towel to absorb any excess glue that may have wicked into the space between the hinges.


8. Don't use kicker or accelerator to speed glue time. Let the glue dry slowly for a strong bond.

另一問題, 究竟條狹縫要留幾闊?

最美觀當然係無縫, 氣流亦係最好, 但要整到暢順就唔係咁易...
所以通常我都會留一根大頭針嘅闊度, 唔太闊唔太窄, 啱哂我呢啲又要整又要懶嘅人...

亦睇過有外國師兄, 寧要最大行程, 放棄外觀...
佢哋留一條闊縫, 再用膠紙封番條縫, 做到最大彈性...

由於啲Hinge落CA黐實後都仲係頗硬(已經都只係落咗一滴CA咁大把), 所以我會用銼仔, 上下兩邊銼薄啲個Hinge, 為求更加暢順...
以Aileron為例, 我會磨到Aileron可以自己重量下降到50%最大行程...
不過要小心同要有耐性, 如太重手, Hinge就會變得太弱, 一撞就斷...
