Its been some time since I gave any public updates to you people (contributors have got weeklies) on the status of the FreePilot project. Now as the project nears completion, I am posting photos and the current status for you people to comment on , advise, criticize , etc. I have run into some issues, most of which have been solved, but still need some help on the others.
- All body work finished except canopy.
- Everything bench tested.
- Some ESC issues (summarized below)
- XBee joystick control perfected.
- Latest ArduPlane 2.5 (with modifications) loaded.
- Battery and voltage sensor connected to APM on-bench.
- Airelons tested to breaking point (still works perfectly)
- Custom control rods attached (flexible plastic)
- On the inside, spruce spars in original design replaced with fiberglass.
- Everything else to get it flying.
To Do and Issues:
- Make the canopy (almost finished)
- Fix ESC heating issues: The 20A JDrones ESC is overheating on bench, without the motor running and just APM drawing from the BEC. My battery is a 11.1v 25C 2200mAh Turnigy pack, which should be suited for the ESC, but it still heats up, even after adding a beefy heat-sink on top. The MOSFETs on the bottom cannot be touched after a minute. I think I need a beefier ESC.

APM, GPS and Xbee recessed in the body

Let me know what you guys think, whether it will it fly or not, etc.
