Take a look at kmots’s thread Four Star 60 building. By a 54 year old beginner. Post #216 goes into detail about cutting and dying the canopy. Pale Rider posted a photo on 4 Star 40 building has commenced! thread post #81 (http://www.rcuniverse.com/forum/fb.asp?m=1946922) that shows the pieces that were trimmed from the canopy, post further down details the Rit dye method.

For my 4 Star (http://www.rcuniverse.com/forum/fb.asp?m=6888862) I cut out the canopy per stock configuration, then, holding the canopy along side the fuselage, I lowered the front of the canopy until the top of the canopy was inline with the angle of the turtle deck and cut the front of the canopy to fit around the front deck of the fuselage, then trimmed the sides to allow for about ¼” overhang. I applied hot air to the front of the canopy to form it around the front deck. Dyed the canopy with black Rit dye and attached the canopy with silicone and small screws.
