Alan just did a video that demonstrates how to transfer your electronics from a Blade 200QX frame to our Phoenix Flight Gear Frames.
He demonstrates the method done without cutting the stock body.
The other method is just about the same except you cutout the mounting section of the stock 200QX body and mount that to the frame and mount the electronics to it just like the stock configuration.
Here is a link to all the PFG 200QX frames- http://www.rc-drones.com/BLADE_c_140.html
