Drilled the upper engine mounts. This is an area that has changed considerably compared to my first XL. The new engine mounts are now configured to hinge the canopy and also serve as attachments to the BRS system (if one decides to purchase it as an option). The gear channel has also been strengthened considerably (new longer and thicker doublers along with the addition of the attachment plate). I will need to purchase AN6 bolts for the engine mounts. The old mounts came with the bolts welded on to it.
