If you mount the N5c canopy without modifying the canopy mount holes you will notice there is a small amount of tension to allow for clearance of the main gear. If you do not like the look of the canopy while mounted like this you can trim 2mm of material from each hole to relieve the tension and the main gear will still clear the canopy as long as the trimming is done correctly.
