Maiden Flight of my new FPV49v4

This is my FPV49v4 with a KFm4 airfoil, designed by FPVTrond on YouTube. The video is quite crappy because it's from an onboard 720p camera. I'll try to get a 1080p soon. It was a short LOS flight because my legs began to shake but then I was pleasantly surprised by the graceful glide slope.

I did the maiden flight with a 3S 5000mah 45C battery. I had to add some lead to the nose to balance out the cg, based on what the "flying wing cg calculator" displayed.
I did order two 4S 5000mah 60C batteries to run in the wing for a couple of reasons:
1. I needed the nose weight anyway, so why not go a bit bigger on the battery and remove some "dead weight" lead
2. After dropping to a 9x5 or 9x6 prop, run the 4S packs for a bit more speed
3. Since the motor and esc can handle 4S, why not try 4S, lol
4. Can you imagine losing all the "dead weight" lead and running both 4S packs in parallel for a much longer flight? WOW!
Anyway....we'll be back with more on this plane!
