I have not done that particular aircraft. I have made my first scratch built canopys and found it was not all that tough for my project. The pictures and text may give you some ideas for yours. do a search here on RCU for "1/5 scale BT-13 build". The canopy and windscreen should start around page 3 or 4. I found I could form the windscreen separate from the canopys and could do it in the oven without vacuum forming.
