Even with a 3000 mah 4s, gps, receiver, & FPV camera mounted as far forward as possible I couldn't even get close to COG with this plane. This is simply a holder that I glue a fishing weights into. The holder then screws into the plywood above the FPV camera. This way I have the ballast as far forward as possible.

I have printed 3 with different weights mounted - 70, 55, & 40 grams. Depending on how it fly’s I can vary the COG by interchanging.

I am starting to get irritated by this plane. Lack of room is a real killer.
