Sounds like standard Hobby King procedure I stopped buying anything of real value from them after it took two months and lots of harassment of HK on my part before I received my bottom of the line Fat Shark goggles. One more thing when it comes to the Naza V2 make sure you ALWAYS turn on your radio before plugging in the power on your quad or the whole package just might fly off into the sunset like mine did. If you do mess up on plugging things in right then start over because the Naza I had did all the right flashing so I thought things were fine that is until it got a mind of it's own. I am staying with the Naza lite because it seems to be more forgiving and if you see my "Y" copter post, the Naza works perfect in that and in a Quad configuration. I also use a Futaba radio, that brand has never let me down because it is quality stuff my first Futaba radio worked fine for twenty years until I gave it to my son who left it in a wet storage area. I used to buy HK batteries too but found the higher end batteries are more dependable and perform consistently and I don't have to wait a month or two to receive them. You may find with the 10C discharge on your batteries even wired in parallel to make 2o may make your quad a little sluggish in it's operation, I have two 25C three cell batteries running in parallel making 50C and for me that seems to work well, I will follow this post because I think this is going to be an interesting read to see how things progress for you. Been in the RC hobby for over thirty years still listen to the experience of others and have done everything from boats to helicopters so I am speaking from experience on my part, love the hobby and will until the day they pack me off in a box.
