Love planes, trains, and automobiles.


Please tell us a bit about your UAV interest

Been flying model planes for 40 years. Started with line control, moved onto R/C, and started experimenting with telemetry about 5 years ago. My sons and I have flown competitively and won a purse or two. UAV could make us even faster.

"I really am of a mixed on this.  On the one hand, the amount of current that the ESC must supply to run the servos, APM, Rx, and Xbee is trivial compared to the motor's draw.  (This points to quality, not quantity.)  But the fact that longer servo l…"

"I realized something that I should have picked up sooner:  When you install an APM in a model plane that calls for, say, a 30 amp ESC, you may need to increase the size of the ESC.  I was recently getting some strange bugs (servos moving erratically…"
