It can be done but it will take a lot of modifications. All of the servos would have to be moved into the rear portion of the fuselage using a hatch for access, a mini servo for throttle up as far as you can get it would clear the center section but you still have the 2 wing hold down bars in the way. Not worth it in my opinion, and this bird sure doesnt need any more weight but it has been done successfully if you really want to do it.
