The Gemfan props are significantly lighter than BN.  They seem to fly smoother than the BN's, probably because the smaller lower torque 1306 motors like less torqy props.

The dry weight is approaching ~150g!

X5SC Quad > "Clean Up" Mods

"Clean Up" Mods

Resolder upgraded antenna wire, thru the hole, to be more robust.

Tape up the battery protrusion, so battery don't fall out.

AUW: 950mah battery, no guards

Mini Quad Build > Detailed "Lower Deck" Pics

The "Upper Deck" with FPV cam, OSD, and harness.  (VTX is not included.)

Total weight minus battery pack

Mini Quad Build > FPV MWOSD Build & Test Flight

Test flight with MWOSD on micro minimOSD.

All solder connections, for weight savings.

Upper "payload" deck weight.
In total, ~3-4g for OSD plus wiring.

Without OSD
(old scale)

With OSD installed
 (new scale)
(OSD + wiring = ~3g.)

X5SC Quad > Battery Upgrade Solution

Last time from:
http://extracurricularengineer.blogspot.com/2016/02/x5sc-quad-battery-upgrade.html

950mah battery too big to fit in X5SC.

Solution:

 Cut big hole in front of body

 Big battery is this big!

 Sticks out a bit in front.

Battery door now closes!

Spektrum DX7S > Backlight Mod

Tested okay

INCORRECT:
Clearance backlight panel to buttons.

Editted instructions for backlight install
(from https://youtu.be/KVazmkjIqPE)

1. Open case by peeling rubber covers and grips, to access six screws
2. Remove SD card, and sd card board
3. Negative source from battery board, on battery case side
4. Positive source from vibe motor.
5. On backlight kit connector:
1. Opposite from black wire is #1
2. #2 is positive
3. #3 is negative
6. Remove vibe motor
7. Remove LCD board
8. Trace LCD (edges) to LCD card reference
1. (Measure LCD height = 9.7mm, 1.5mm protrude from edge)
9. Remove LCD, and from brackets
10. Install foam tape on LCD card.  
11. Install backlight to LCD.  
1. Good spacing to buttons, opposite end clearance with mounting screws
2. Backlight wires opposite vibe motor
3. Black backlight wire is DOWN
12. Tape on LCD two edges, and backlight edges
13. Install LCD to backlight kit
1. Use mounting screw holes to center
2. Watch for protrusion.
14. Reinstall LCD broad, reconnect.
15. Reassemble all.

Mini Quad Build > Cleaned Up ESC Wiring

Cleaned up ESC wiring by directly solder motor wires to ESC, which involved cutting and exposing nice ESC shrink wrap.
Re-shrink wrapped only bottom half to keep ESC LED's uncovered.
Removed ESC mounting pad.

Total vehicle weight savings = ~1g
