LoneAL,

I like the props, I don't use filters and I fly off of grass.
As far as wheels, I would go with 3", these have worked for me.
The 2 1/2" are too small.
The weights, just check them often, they can come off.
Small repairs in your coating you can use clear packing tape.
Larger ones are different story, use monokote or whatever you used before.
If you do crash bad, save all the pieces. Even if you have to make new parts, you can use the old ones for templates.

Good Luck

Bill
