As designed, the wing is mounted with rubber bands. If you've seen a bolt-on, it's a conversion.
wow, I didnt realize that they were doing these conversions at the factory now. My LT-40 ARF came with a bolt on wing using 2 nylon bolts. Unless they did the conversion at Tower Hobbies
I do belive that the kit version is banded, and the ARF is bolted.... but I could be wrong.
