Airtech,

There is a thread on a different site that may have some insight. It seems that some kits have this issue and others do not.

Some cures include:

1. Squeeze the cheeks together when sliding the canopy in, this creates a small gap between the top of the cowl and the former.
2. Sand the top of the former causing the issue. CARE should be taken that too much is not removed.

Are you able to get the canopy on at all? Or is just a pain?
