Frustrated with not being able to take off & land in "park height" grass, I've made some really big wheels
About 4" diameter, of 1/8" plywood, with a wood hub infused with thin CA glue and brass tube bearings:
I put them on my pusher camera plane:
On a flat surface, the prop clears the ground by 2". The three of them weigh only .3 oz more than the original 2" wheels.
I just took it out and tried it in a local park and they work great! Take off, land, taxi around; no problems
