E-Flite Opterra 1.2m landing gear version 3

prusaprinters

<p>This is my 3rd version of landing gear for the E-flite Opterra. Version 1 and 2 used double sided tape to attach to the unmodified keel of the plane. On a semi-hard landing I managed to break the plastic keel instead of having the tape come loose.</p> <p>This version completely replaces the existing keel with a 3d printed one.</p> <p>This is a big print. It requires a 300x300 printer to fit diagonally as it prints all as one piece.</p> <p>It has a little winglet on it just to blend in the rear wheel arms that help give some support to the landing gear wires.</p> <p>I use RC Canopy glue to attach it where the existing keel used to be.</p> <h3>To install:</h3> <ol> <li><p>Gently pull the original black plastic keel off.</p> <ul> <li>The glue used is a white caulk like substance so it does not actually take much force.</li> </ul> </li> <li><p>Dry fit new keel onto plane.</p> </li> <li><p>Mark where the servo goes.</p> </li> <li><p>Cut a hole in the foam of the keel just deep enough for the servo to sit flat in the keel.</p> <ul> <li>If done right only a tiny bit of the back of the servo will poke through (see pic). The piece of foam you cut out is more of a wedge shape when viewed from the side.</li> </ul> </li> <li><p>once you are satisfied with the fit. use a flexible, low-bond strength glue to attach the gear to the plane (you want the glue to break in a crash so it is repairable.)</p> <ul> <li>I used Sig Canopy Glue.</li> </ul> </li> </ol> <p>I used 3/32 wire for the gear. It should be tall enough to have at least 1 inch - 3cm of prop clearance when sitting on the wheels.</p> <h3>Print Settings</h3> <p><strong>Printer:</strong></p> <p>Tenlog D3 Pro</p> <p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div> <p><strong>Supports:</strong></p> <p>No</p> <p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>.20</p></div> <p><strong>Infill:</strong></p> <p>20</p> <p><strong>Filament:</strong></p> Inland PLA+ </p></p> Category: R/C Vehicles
