They are extremely springy. I dont think its possible to break one, have you broken any of yours? It would have to take a very brutal crash i would think.

Nope. Never broke one. Mine are held on with zipties, so anything extreme breaks them off

Well. I managed to break one on the right arm after an "emergency landing"

So i replaced the gear on the left & right arms with my trusty rock-crawler tires and left the tail alone. Then today I broke the PVC leg on the tail, and now i have all 3 rock crawler tires zip tied to the copter.

I tried the same landing gear and despite the fact, it's geniusly simple and excellent for landing, I noticed some oscillation during flight - especially in windy conditions.
Meanwhile, I switched to an even simplier solution from the Tricopter V2.6HV build using 3 plexiglas pieces.



This way, the Tri not only seems to hover while stationary, its landing gear is nearly invisible during flight and the whole Tri looks pretty clean now. It weights only the half (45g savings), but the best thing is, that the oscillation is almost gone and for landing, there is more stability.

Unfortunately, I don't have a better picture at the moment..

ah someone who has built this version. does it work well? the CF isnt cross weaved and so it could easily break in a landing since it has bolts through it. The ESC wires are extended from the battery which is bad (should extend the ESC -> motor wires).

Here's mine

Inspired by rcbif and subaru4wd here's my take on home made landing skids.

I started out making some like rcbif but using my heat gun to soften things, which worked great, and then realized that existing zip ties would be a bit in the way for mounting.

So first I straightened out a whole strip of 4" pipe by 1/2" then bent it into these. Pondered what to use for skids, decided to try wood instead of more pipe as it's significantly lighter. The 13" long strip of PVC weighed 22 grams each. The same length of wood was 8.

I just bent everything free-hand over the edge of my workbench. If it works and I need more then a jig would make them a little more uniform.

I'm just getting this tricopter going. Did a short maiden flight last night in the dark, without the skids. Hope to steal time to test it out with more room later.

I made the skids pretty high because I'm flying at our farm and the grass is longer, so I'm hoping this will get the props high enough.

BTW, anyone know how PVC compares in strength/weight/durability to acylic (plexiglas) or polycarbonate (lexan). Realized that I have some of both that comes "pre-straightened" )

I'll report how they work out. Thanks again for the inspiration.

cheers,
Andrew

That looks great, and its a great idea! PVC is pretty hard, and it only flexes so much before it breaks. Plus when you bent it, you created weak spots. You might want to try connecting something to each wooden skid so they cannot spread apart from eachother. This will keep the PVC from tweaking and snapping.

I was suprised how quickly I broke my PVC landing gear, but my Frame is alittle heavy and I did come down on it pretty hard sideways a couple times.

I went back to the trusty rock crawler tires:


I am not sure how much they weigh, but they are indestructible, and do a great job of protecting my motors too.

Here is a solution for F-450 Skids

Here is what I've made up for landing skids, I've sold a few sets to people who have had interest in them.

Not for a n00b. If you land hard with the force on the edge the zip ties will snap. Land hard with force on the face and the foot will snap. Don't want to spend all day on the band saw and drill press making new ones. I think I might try plywood next.

Also what would the strength be of this design with 1mm carbon fibre? Is aluminium and wire a no no because of radio interference?

EDIT: Lexan looks interesting too...

Okay this thread needs a bump.

I am out of idea's for landing gear. I have been using Pool Noodle, but it seems to be soft and gets torn apart rather quickly.

The stock is 1/2" aluminum flats from HomeDepot or Lowes.

I think this is the next idea I am going to steal

Thanks Rick!

$4 junior wiffle balls from target. They absorb shock well and are fairly light.

What do people use on snow?

This is my first winter with my RCE2.5 tri and my zip tied pieces of plywood won't do any good. The wiffle balls look promising but may not be tall enough after I add the 2.6 camera mount.
