This frame fit the requirement of stretch X, flight controller not part of the top plate stack, and replaceable arms. I'd like to experiment with getting the camera a little forward and lower and the VTX on the bottom of the top plate as it is on the x210 build. I'm not a huge fan of VTX antenna coming out of the top plate. The DTFc drilled out and soft mounted on o-rings seems to be doing well. I'll probably build another using a F4 board and some 4-in-1 ESC.
