Glide investigation: secure the tail and measure balance before another throw.

• Extended D01 keel rail from five to eight positions at 4 mm pitch: three new holes behind the old rear hole.
• Checked wing and saddle clearance at all eight positions. Retained wings and zero-degree tail geometry.
• Added a complete fit-selection print sequence and a separate bench balance stand.

Read the fit-first section before large airframe plates. Print each installed item once; alternatives and test copies are not additional installed parts. The supplied files preserve required orientations. Do not scale a tight socket or let automatic orientation change a support-free layout.

Print five retained pieces including the new keel, then exactly one saddle, one matching zero-degree tail and one tail pin: eight installed pieces. The stand and mating samples stay on the bench.
