This canopy fits the CMPro P-51 Mustang 68 inch wing span.
The canopy measures : 14 inch long, 4 1/4 wide and 4 1/4 tall.
The plastic it is formed with is .030 PETG, the same material soda bottles are made with so you know how tough it is.
The thickness is the same as stock however the plastic will not yellow like the cheap plastic that is on your plane now.
If it was my model, I would attach the canopy with silicone rather than the ugly screws .
Silicone is compatible with glow fuel and makes a bond that can be pulled if needed.
