Im going to go to bigger wheels also. Yes, grass is hard to deal with when you have small wheels.
Wheel pants just get messed up and get in the way in my case.
Just got back from flyin a few minutes ago. I flew 4 packs with the Cub, but didn't record any of it. I did make some video's of my friend flying his 1/4 scale, 26cc, Great Planes P6 Hawk.
I still need to upload them so it will be a while, in case you want to see them. My You Tube username is "n6ugyham". They should be up within the hour, unless the camera screwed up again. Some of the recent video's have had some weird clouds of color going on, so we'll see...
