Hi HyperHelis, welcome to the forum! You're going to want a Naze32 Full instead of the Naze32 Acro which Flitetest sells to add a GPS. The full board costs about twice as much as the acro one (~$50). Even then, gps functions on the Naze are still a work in progress and will be mediocre at best. If you really want full on gps I would look at larger controllers like the Pixhawk or Naza, etc. Of course those controllers might be too large for the versacopter. Something smaller might be a Sparky V2.
