FMS 800mm Beaver Wing Strut Replacement (Left & Right)

FMS 800mm Beaver Wing Strut Replacement

I managed to break one of the wing struts on my FMS 800mm Beaver and decided to model a replacement instead of ordering new parts.

This is a complete one-piece replacement strut that fits either the left or right side of the aircraft.

The replacement closely matches the original part and has proven to be plenty strong for normal flying. Mine is printed in black PLA and actually looks quite good on the red and white Beaver.

Features

• Complete one-piece replacement

• Fits either left or right side

• Fast print (about 8 minutes)

• No raft or brim required

• Simple installation

Print Settings

• Printer: Prusa Mini+

• Material: HS-PLA (used for mine)

• PETG is recommended if the airplane may be exposed to high temperatures

• Layer Height: 0.20 mm

• Perimeters: 3

• Infill: (doesn't matter, there will be none)

• Supports: Required for both attachment ends

• Raft: No

• Brim: No

Installation

Print the replacement, remove the supports, and do any light cleanup needed around the fuselage attachment end for the best fit. Depending on your printer's tolerances, a little sanding or trimming may be helpful.

Notes

PLA has been completely adequate in normal operation. Like any PLA part, avoid leaving the airplane in a hot vehicle where the material could soften. PETG would be a better long-term choice if the model regularly sees high summer temperatures.

If this gets another Beaver back in the air, I'd love to know!

Design Notes

This part was reverse engineered from the original unbroken strut. Measurements were taken directly from the factory part, modeled in TinkerCAD, then refined through several print-and-test iterations until it matched the original fit. The final version installs like the stock part and fits either wing
