R5.1 · gear mounts fit without pads

R5.1 closes the gear-deck gap in the four printed mounts. Each bearing base is now 7 mm thick and seats directly against the existing plywood deck. No separate bearing pads are needed. Use the same M4×30 and M3×25 deck bolts with washers and locknuts; the base + deck + doubler stack is 7+6+6 = 19 mm. Check actual washer thickness and full locknut engagement. Keep the supplied print orientations and inspect the sliced layers with supports off before printing.

Use R5 mount instructions instead of earlier split-mount diagrams. Other airframe assembly instructions remain applicable. Print and dry-fit the mounts first.
