I've used canopy glue and E6000 with sucess, but in your case Mark i'd get someone else to do it

The thread that Jason started asking the same had some great ideas. One was using bits of balsa, cyano'd to the fuz to hold the canopy in place.

What Duncan meant to say is that he Used Jason's E6000 with success and never gave it him back!
Mark
The balsa blocks glued to the fibreglass to support the canopy perfectly in place works very well. I then used a thin tube pushed the canopy glue tip and slid it along between the canopy and frame while squeezing to glue it in.
