Hi Benny I'm replacing my canopy due to an inversion and subsequent broken canopy. I've had a bigger canopy blown locally and am using the existing canopy frame and fuselage as a jig for both location and shape. Note that the rear of the canopy and the top of the rear deck make a nice straight line and I think this is important to minimise turbulence .... I will be making the rear deck to conform to the new canopy (and am making it removable for access to the rear fuse ).
Contact me off list if you wish. I live in Frankston Vic .... Cheers Martin.
