Break-Away Landing Gear
Editors Note: This article is by request from Jessy M @ RC Universe. Good to hear from you!
E-flight electrics are high quality, however, for the less-then-perfect pilot, the landing gear of these planes can, and will at points, fail. A gear collapse has happened to us many times with our Extra 260 on a few rough landings, so we decided that this plane needed some stronger gear. The process was simple and can save you a lot of grief and body damage to the plane.
First, grab some SIG threaded hardwood blocks, nylon bolts (that fit the SIG threaded blocks), and 5 minute epoxy.
The process is simple
- Remove your aluminum gear and size up the hardwood blocks into the current “channel” that is set up for the brace to fit into. Note: Due to the blocks size, your gear will no longer be set down into the channel, rather it will sit flush with the body of the aircraft.
- Mark the placement of the blocks and the center hole in the channel. You might have to remove the stock metal threads installed by E-flight and drill a larger hole to accommodate the nylon bolts as the nylon bolts will be larger in diameter and length and will need to go through the wooden bottom of the body when they are threaded.
- Size your bolts diameter to the aluminum landing gear holes. Odds are you’ll have to drill larger holes in the aluminum gear to fit the nylon bolts.
- Epoxy your aligned blocks in place.
- Take your nylon bolts and where the head meets the shaft, cut 1/3 of the way through the bolt shaft. Why cut the bolt? Upon any impact, the bolt will “sheer off”. Due to the lightness of many park fliers sometimes a nylon bolt is just as strong as a metal bolt. Here we keep the strength but help it along in case of a really rough landing. Trust us, this works great and has saved us lots of time and $$.
- Attach your gear to the aircraft using the pre-cut nylon bolts and fly-on!
This tip works great for all kinds of park fliers with landing gear mounted in a similar fashion. When it comes to the lite-ply & balsa aircraft, doing a few modifications up front saves time and expense. And while metal bolts and solid connections are great if you can land like a butterfly, the rest of us need a break from time to time. Literally.
