Ok, so I saw what mccalljc (also know as "MC-Magic") did a while back with the zip tie landing gear.
F1wanabe made a video with it flying real nice off the pavement.
Ever since I saw this I wanted to try it.
Here is what I got so far (have not fully tested this yet).
- Large zip-tie around a foam cut out wheel.
- 2 small zip-ties secure the "post".
- Then glue/tape the large zip-tie to a foam support (2 inches x 5 inches).
- Then tape, glue, or velcro this to the bottom of the plane.
- Can be put WHEREVER is the idea!

I plan to fully build, fly, and test this in the coming months.
But if someone can pick up the testing and get us ahead, that would be great!

Ah, velcro this on instead of glue. That is very useful!

Kewl.....we do these sorts of things for cable management but can't figure out why I didn't connect this idea to start with.

Slick idea and I know I have a couple of wheels around here.

I am hoping to finish a snow skimmer idea this weekend and will post if that works okay.
Fly like your mad at it.

Yeah, thinking about it more... having these Velcro on and off is really going to be key.
Sometimes you want them, and sometimes not. Being able to take them on and off at the field is a high priority.

I like just the zip ties myself. Aside from the added drag and weight of these assemblies, I believe IMHO that the formed "strut" will be succeptable to folding under upon landing.
I have, however, been wrong before.
Just another day in paradise!
Any day above ground is a GOOD day.

Because I'm looking at using the parking-lot at the local stadium, I'm so glad that you posted this. Unless I spend 50-round trip, it's a pain to get to the coastal flying site here in Lima. This'll gibe me a way to not tare up my planes at the parking-lot.

Thanks again,
Peru

There's not a lot of open-air parks around here..... just rock or trees
Life is about adapting. I can't fly planes anymore, so I do the RC stuff. It's a blast as well.

Info on landing gear

In designing gear/skids, the nose wheel is the killer. The battery (lots of weight) causes the brunt of actions. F=ma = crunch if wrong design.

1) Steering is a big problem(goes off to one side) until airspeed is up and rudder takes over. If no rudder, ties will control you.
2) Ties wear down, especially on concrete using the smaller ties. Also, uneven drag by the 3 skids causes change of direction.
3) The nose gear needs high re-enforcement to keep the battery from collapsing the gear for landing/takeoff.

Takeoffs can be done, but it the landings that is where the action happens. It may work for a couple of times, but takeoff/land 10 times and see what happens. That's why I put them aside.
I like to design and fly unique planes.

I did a swamp buggy way back when, turning it into an ice-buggy using dulled blades mounted on a rod a ran across the bottom, and a small L bracket on the back for steering.... was pretty kewl.

This is really helpful man. Once again, all your experience really helps out. I'm able to save alot of time.

Well thats good to hear. This is what I'm hoping these things can do. Just fill a small niche roll for these kind of situation.

I was able to get some work done on the landing gear tonight! I'll take some pics tomorrow and post them up here! Talk to ya soon.

Ok, this landing gear is going pretty good actually.
Really good progress so far. Here are some things I've learned so far.

1) BIG zip ties are great! I had some thick "24 inch long" zip ties and they provide alot of strength vs the smaller ones.

2) Use tape to really wrap, pull, hold, and secure it in place. Zip ties are taking the "stress" and the tape is just keeping things from moving around.

3) Have the nose gear taller than the rear gears. This way there is an angle of attack for take off. The design of the front and rear gear is the same. Just more or less zip tie length.

Hi Dave, sorry this reply doesn't apply to the zip ties, but that's cool stuff too and interesting pros and cons of it huh.....anyway, I'm posting this question to u here, bc it won't let me put over 420 characters to u , personally, it said to me, so I copied and pasting it to u here, hope that's ok? here it is.. Love the New Home Page, winter adjustments* for weight vid., Dave!!! IT'S AWESOME!!!+ WITH...a Real Fighter Jet fly by, was that timing and location planned*? For that FX? Omg, too cool+ thx for good ideas weight wise etc. Now I have to go weigh my SU-34/V4 bc u just made me scratch my head and lift my jaw off the floor. after that vid. I need a camerman like the one of that vid too. A+!!! ALLLLLLL the way around on this vid. Thx!!! + where was this vid. taken at, town,state wise?+ weather conditions? Awesome Hovering in middle of vid. Wow, High Alpha to the max rite then. I'm very impressed with this pilot...is it u?
