tool: D150: 


tool: D62:  Options


tool: D50:  -c {channel}   Specify one channel from 1-8.


tool: D100:                 Otherwise all channels will be driven equally


tool: D147:  -f {hz}        Specify pulse frequency, otherwise 50hz is used

tool: D27:                 DO NOT use power option with ESCs


tool: D112:  -p {position}  Drive servos to a position between -1.5 & 1.5


tool: D22:  -e {throttle}  Drive ESCs at normalized throttle from 0-1


tool: D57:  -u {width_us}  Send pulse width in microseconds (us)


tool: D15:  -s {limit}     Sweep servo back/forth between +- limit


tool: D13:                 Limit can be between 0 & 1.5
