Well having had this for a couple of days now, I can definitely say it's nice (better be for $250). The IOC channel interception scheme works as they intended and does NOT interfere with resetting home point. If you toggle S2 5 times, the gear ignores it as it should.
The servos included are
Hitec HS-65MGs, which are a high quality metal gear servo with high torque. These retail for about $30 each, so at least they're not using cheap micro servos.
The hinges are what appear to be machined A/C grade aluminum (not the cheap Chinese stuff). The gear can be a bit wobbly without power applied, and could potentially cause a tip-over if you're not careful prior to powering up. It won't tip over EASILY, but it CAN if pushed too far. Once power is applied to the battery, it's quite solid and I would have no qualms about landing on it. The hardware has the added advantage of extending the legs about 1/2 inch, which as any P2V+ owner will tell you, is a welcome addition.
The CF "ledge" that houses the mechanism also doubles as a nice place to drill a couple of holes for Phantom-side antenna mods. As you can see in my pics, I've got 2.4 and 5.8 Ghz LHCPs installed in them. Also, contrary to the instruction video, you do not ned to drill holes in the side of your phantom in order to install the servo leads. They're plenty long enough to cleanly go through the openings in the hinges and up through the leg mount holes into the body along with (in my case) the antenna leads.
I can't vouch for the functionality of the compass mount (which I didn't need), because I use an external GPS/Compass puck mounted above the shell. However I don't see any reason why the provided mount (which places the compass in a fixed position above the hardware shelf) wouldn't work unless there's EM issues being closer to the electronics.
Overall, well engineered and clever product that works well and I have not noticed any appreciable loss of flight time, although based on the fact that it IS extra weight, there must certainly be
some penalty. I bet if these guys could get the price $100 lower it might catch on, at least with the "gotta have it" crowd.
