While this model utilizes standard parachute recovery, but I would like to eventually get the model to glide recover, kicking out the motor with either a streamer or parachute for recovery. I've seen this technique used on the Estes Space Shuttle and SR-X models.
The balsa fins (wings) are laminated with 110# cardstock for strength. Carbon fiber tape could also be used to strengthen the fins further, especially the longer ones. TTW is used wherever possible.
A version with wing-tips will need to wait for RS9 to model properly.

P.S. Please note, textures on Main Body Tube and V-Tail fins should have "Rotate around R-Axis" selected. Rocksim does not seem to be saving this setting in design file correctly. Attached images are correct.
