Airborn 1600 build Fuselage bottom keel and hatch

I have been working with the stringers for the bottom side of the fuselage cowling.
After doing that part the fuselage has a bottom keel that runs about 3/4 the length of the fuse.
This also is the area where the landing gear exits and the bottom hatch is fitted into the fuselage.
The landing gear exit is relatively straight forward just a 5/32 gap between formers to allow the gear wire to exit and allow for pulling the gear out if needed. The hatch in the bottom is a bit more involved because of the flat bottom of the fuselage superstructure and then the angular keep shape over that. Also the fuselage bottom is on a curve at the point the hatch needs
to be place, then there is a hatch latch needed to release the hatch..
The hatch needs to be relatively long to allow to move the battery pack along it to allow for CG adjustments when motors are changed due to their difference in weight.
