I have one I purchased used. OS 60 in the nose and a 46 in the tail. All tail & aileron servos are mounted in the center of the main wing. No flaps (it doesn't need them to slow down). If you are going for a military scheme, spinners aren't necessary. The other servos are mounted in the middle next to the gear block. Only one servo manages both engines, one for steering and another for the lights.

On my model, the wing braces are necessary and functional. The person who built this plane did not make these strong enough. I would suggest a remote needle valve for the rear engine. This one tends to get hot and overheat in flight.
