Default Big honkin' wheels

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

Nice. In my experience, tall, skinny wheels do the best in tall grass.

I suppose I should have done some touch & go's, since it is all about the wheels, but I didn't...

I don't know if you ever fly off wet grass,but if you do,a couple of coats of clear polyurethane might be a good thing.
After all that work,you don't want wobbly wheels due to warping

They have a couple coats of clear lacquer on them, plus the "tires" were also coated with CA glue. They won't last forever, but should hold up pretty well

Nice job with the wheels big, and skinny makes a difference.

I have to use the MPI light wgt. wheels to fly and land at our club. Field is cut like park grass. While the fuel guys clean the oil off their planes. I have to clean the green grass stains off of mine.
