Yea the sun does that, and it'll just bend back after about a week. At least mine did. I ended up snipping off the little plastic needle and drilling a small hole where the needle was. Then I cut a paperclip to make a new needle and epoxied it in. Finally, I painted the whole thing red. I works smoothly now an it'll never warp up again. Just make sure you see where the needle returns to before you take the warped one off. you want to put the new or fixed one in the same exact spot or your speed will be off.
