Yes I will be one more person developing drones. :-)
I have uses for the drones, so it's a definite area of activity for me.

The DJI copters are pretty nice. Flight time is better than average, and flight controls are supposedly good ( but I have not flown one myself). The main drawbacks are that the signal strength limits the DJI unit to about 300 feet range. Also, some users have had "fly always" with the DJI's. Meaning the unit went up into the sky, and didn't automatically fly back when commanded to do so. So your $1000 drone is gone ... Just gone. Not all these problems were operator error, so there are some bugs in the system that they are still working out. Just the same the DJI's are pretty nice. :-)

Good luck,
Pete
