Chris, can you post some details about your Quanum headset mods? Also, did you just get the headset or did you get the bundle that included the RX, TX, and camera? I'm wondering if the RX will work with the Eflite Nano QX FPV? I'd like to get the Nano for house flying this winter and get something bigger in the spring. I just can't justify the cost of the Fatshark headsets, yet.
I got just the goggle kit, and purchased a different TX/RX setup. Looking at their bundle, the receiver looks to be the same one I bought. Having 32 channels means it will talk to basically everything, including the Nano.
As for my mods, I just built an extension onto the foam box that sets the display about 30mm further away from my face. I found that even with a good magnifier lens it was straining my eyes to focus.
Speaking of lens, I robbed the lens out of a pair of these:http://www.amazon.com/Jewelers-Lighted- ... 005VR19ES/
I also have a set of these, and they come with several different lenses. Should also work and gives you more options:http://www.amazon.com/Housweety-Profess ... B005VIG6TA
I mounted the lens to the stock frame using a bit of hot glue.
