The 850 will have to be placed crossways all the way forward directly behind the motor mount for best CG. It flies great like this, though one could possibly use a slightly heavier battery if they would like it more nose heavy. If you can get it to run with 5g servos that would help trim a bit of weight too. The "Taillet" makes a massive difference in directional stability. the turns feel steadier and more "on rails" when I've added this to any delta(tailed or tailless) so far. It is a tiny trade off to the high alpha ability but not noticeable if you don't make it too large. The size I've added works great, but feel free to experiment if you wish.
