After a rather damaging Raptor 140 crash (see http://ardupilot.com/forum/viewtopic.php?f=77&t=4879), I built the the 140b, which is essentially the 140, with some improvements:
-Carries 10Ah instead of 8.8Ah, and will eventually carry 15Ah. Should allow for 75km flights at 80kph!
-Improved electronics placement that allows for additional batteries to be carried directly over the CG point.
-Improved weight distribution allows for 90% less reflex on the elevons, reducing drag.
-80% precipitation sealed, an improvement over the 140's 50% sealed (batteries, motor and ESC are still exposed)
-Uses the 140 Kit I sell on my site and follows the build videos 100% (you have to use what you sell IMO!)
It's maiden flight went flawlessly, it should be just as good and even better than the original Raptor 140.
See you next week!
