near death T-Rex


The latest starboard cyclic servo failed after 5 minutes. It was the aft cyclic servo which we gimbal locked & overheated earlier. https://www.rcgroups.com/forums/showthread.php?t=906358 There's also a theory that the CC-BEC was damaged in a crash & is burning out the servos 1 by 1.

Well, the T-Rex 450 has been so problematic, plans R already being drawn up for yet another airframe in 2009. That would be 3 airframes consumed in operating 1 UAV. Still more efficient than mortgage stimulus packages, as hard as it is 4 a certain country to believe.

The next airframe would be a quadroter. That's right. Except for the motors, quadroters can be built out of cheaper parts. Quadroters R perceived to be safer. Quadroters have more space for electronics. The main concerns R flight time & damage to expensive motors instead of cheap landing gear. There would be head on crashes into motors, bent casings, bent shafts, broken props, & bank failures.

With all these crashes, now would be a good time 4 U 2 view the Nevada test site.

Jack,
There's a nice quadrotor with about 3Kg thrust that you can build using DT-750 motors (in the quadrotors forum), these cost $12 each and won't break the bank if you buy half a dozen of them (check also the thread about this motor here at RCG).
AFAIK quadrotors are very stable, can fly very slowly and carry a relatively heavy payload.
The Nevada atomic bomb test site pictures are a sad reminder of humanity's worst facets.
