Bixler Hatch Cover With optional FRSky Antenna Holder.

Here is a Bixler hatch mount for the rear fuselage. Cut a wedge shape hole on the top side large enough to hold the wedge. Cram all your electronics in then use a ziptie to secure it to the fuse. I printed it in ABS with low infill, I recommend 10-20% in order to keep it light weight. Available in 3 options...
1) Blank (If you just want the cover)
2) With a Hole in the center (useful for passing wires to the outside)
3) With a hole and FRSky Antenna Holder (shown in the picture).
