form buildyourowndrone site FAQ:

The DJI Naza Lite can be used on QuadCopters, HexaCopters and Y6 mulitcopter frames, at this time there is no support for TriCopters or OctoCopters. You should not use the Naza on frames with a diameter of greater than 65 Cm’s. The Naza M V2 GPS supports the same frames as the Naza M Lite with the addition of OctoCopters.
