By request, this is a quick review of the DJI Naza Lite flight controller with GPS.
Pros:
it works
simple to set up
from a well-known manufacturer
can be unofficially upgraded to a Naza M
Cons:
precision isn't as good as more expensive units
pretty basic feature-set
Conclusion:
It does what it says on the box and is one of the cheaper brand-name options for those wanting to build their own non-racing multirotor craft.
