Canopy frame started.

I made a small modification here. The rudder and elevator servos are located in the bay below the rear of the canopy frame. I extended the top bulkhead at the rear of the canopy about 1.5" aft to accommodate access to the servos. The next forward canopy frame bulkhead is in the proper position, so the sheeted part of the aft canopy frame will be longer by 1.5."
