While this is the 3rd "Build Log", I've done nothing more than grouse and show photos of the various components. And this one is no different! I started out with bare curiosity, how heavy is the bare wing?
According to this online calculator, the drive train should provide more than its weight in thrust, so hopefully I can throttle back to a lower speed for long cruises.
The servos for the elevons also brings up yet another interesting issue. The original placement (see where the multi tool is pointing) gives it probably the best leverage against the elevon, but the servo cable is simply not long enough to reach the receiver if it's mounted in the main electronics bay.
So either a) I run the servos closer to the center bay, or b) I get extension cables, which adds weight.
This also does not include several other items that I want to include down the road:
- FPV Camera
- Video Transmitter
- OSD (on screen display - basic stuff like battery levels, but can be more like heading or attitude indicators)
- Gopro/action cam
The Gopro itself is just over 80 grams, so that brings the aircraft very close to 600 grams all up weight (AUW)! Adding in the OSD/FPV gear will probably add another 100 grams, so maybe 700 grams in total? But we'll see.
