Not all the kits seem to suffer from this issue. If yours is having issues, there are a few things you can try.
On my first E5 kit, I Dremel off part of the canopy. One side came out better than the other.
Good side.
Not so good side.
On my other E5 kit, I just used the 700E QuickUK magnetic mount long studs. It gave me sufficient clearance between the canopy and the main gear. As a bonus, the canopy is now much easier to insert and remove.
A third option would be to just add a few M3 washers on the front canopy mount studs to shim the canopy laterally.
