One of the best aspects of this hobby is helping out other people, which has certainly been made easier thanks to the internet
The back plate (the bit with 'REAR' printed on) is not glued or screwed, it locates in place firmly to remove you slightly bend to pop it out. This plate made out of black ABS sheet, just finishes the back of the cockpit off and stops the tank and air tanks being on show.
Glad to have been of help
