Yes, PicoPilot is not a breezy plug-n-play system, but once you get it installed and working correctly it is pretty reliable and robust.

The issues are IMHO not really flaws per se, but rather its non-hobbyist-friendly nature with regard to integration. It takes some effort to set up the model's control surfaces properly and to tweak the PP gains. Having "gone to school" with my first intallation/integration, it is going to be MUCH easier the second time around.

Sure, it would be nice (and UNAV would sell more units) if it were more PnP, but looking the the more advanced stuff they offer I get the feeling they're shooting more for the pro market.
