 ===== Notes =====
   - Edges of frame pieces should be sanded to avoid wear in wiring
-  - Camera has been mounted with rubber O-rings due to lack of better mount
+  - <del>Camera has been mounted with rubber O-rings due to lack of better mount</del>
-  - Receiver antenna has been reinforced with cable tie + heat shrink
+  - Receiver antenna has been reinforced with a cable tie + heat shrink
   - Don't attempt to flash the ESC firmware, 1 of 4 is likely to fail if done via FC, however changing settings is ok
+  - The original camera wasn't too bad in adjusting to illumination changes but lacked dynamic range when flying towards a low sun
+  - Remove the microphone from the camera, you don't need it
+  - Replace nylon standoffs with aluminium standoffs for extra durability
+    * The provided M2 screws are however good and long enough
+  - Older Kingkong 1935 props have a much tighter center hole which may not always fit the motors and push the shaft out of the motor instead when the prop is inserted
+    * More recent Kingkong 1935 props fix this issue with a slightly larger center hole, those can be identified from the center hub which isn't any longer fully flat
+  - RunCam Micro Swift 2 will not fit with the default standoffs with the included mount
+    * With some plastic removal, it's possible to fit the camera using a custom mount while still using the default standoffs and having possibility to get some angle to the camera
+    * Only the height is a restricting factor
+  - FrSky XM replaced with FrSky XM+ due to [[https://www.youtube.com/watch?v=-iHfjfsTRsQ|random poor range issues]]
+===== Wiring =====
+{{:rc:files:l90:lantian_l90_wiring.png?direct&550|}}
+  * Don't mix V1 and V2 FC and ESC board, the connecting wires have different outputs
+    * V2 is much less messy to use and it doesn't require a separate battery wiring to FC
+  * The battery wires are on the bottom of the ESC board so be extra careful not to let plain wires touch the frame
+    * Use a piece of electric tape just to be on the safe side
