Yeah -- I just bought a Twist from a hobbytown USA store, and when I got it home (4 states away) I pulled everythingout and realized that the nose of the plane was off a little -- from the firewall back everything was fine, but one of the pseudo-cowling sides was angle in about 1/4 inch more than the other.

I called horizon, and they said they could replace the fuse, but I would have to ship the old one back.

I did a little test fit of my engine, and everything still fits, so I wasn't going to bother with them - too much hassle.

Finished building the plane yesterday -- looks great, everything else was fine, I'm just waiting on a replacement muffler to show up and I'll be ready to fly.
