Modify compartment to hold LiPo batteries. Takeaway: Moment & Balance now stable for 3 LiPo batteries ahead of Landing Gear Section. As this is a pusher prop plane, load balancing and structural factors weigh into where and how 15 oz. batteries are placed. To make it flexible, two batteries, then three can be housed here. Two carbon fiber rods (not shown here) added to the rebuild of the fiberglass battery cover (also not shown here).
