I had a world models 1/5 cub. I really liked it. I bought it cause I heard a lot of bad stuff about cubs, I had to find out for myself. I had no trouble with mine. Unfortunately it was lost due to a bad battery. I liked it enough that I'm going to build a 1/3 scale super cub that I've got plans for. I dont know why so many people dont like the cubs. Maybe they just dont know how to set them up.
