Efficient Landing Gear for Large RC Plane

I am going to be using this on my 83" flying wing, i have not yet tested it but will soon hopefully.

Update #1 5/8/15
- Just finished designing the front gear. The front gear will need one RC car shock, 1/8' aluminum rod, and a 1/4' aluminum rod, 3/8" Rod for wheel axle, and M3 screws w/ washers. I will upload the files as soon as I can.

---> This is literally the first modeling project I have ever done, if you have any comments or suggestions i'm open!
