Sad to hear about your Naza issues I have 2 lite installed in two different quads and they both fly great, even mounted with a mini quad (not mounted with GPS), the second one do have the GPS and I love how it fly's. The third one is a V2 and is mounted on a big quad and I love how it fly it is very reliable. Any how as Snarls mention the wii controller seems to be working for a lot of people great but you do need to get into the learning curve and have to adjust so it fly's 100%.That said, NAZE32 seems to work also and the interface seems to be a little more user friendly and simple enough to make your way. Now there are two options available the funfly and acro, both seem to work great but depending on what you are looking for. mention something under $99.99. Multiwii Pro with GPS and you will have to learn more on how to set it up 100% into your needs. Hobby King is also selling now the knock off the HKPilot32 Autonomous Vehicle 32Bit Control (PX4 open-hardware). all included 147.28, need to add your GPS thou.
I would check more about why your Naza lite (if you still have it) is not working right, like setting up all your ESC to the same throttle pulse, make sure that all the prop directions are right, your engine layout is also correct. Your GPS/compass is also free of magnetic interference (not close to ESC or video transmitter specially 5.8 ghs. GPS and 5.8 dont like to play along when they are too close)
Also your MCU is dead center (some people do mount MCU out of the center but I have not try it).
Remove the red wire from your ESC. (better to have them remove than burn something up)
Your channel lay out is also correct, Aileron Elevator Throttle Rudder.
Hope this helps and good luck!
