Lunchbox 斷車腰彈弓

As you know, that's Lunchbox's weakest link: 斷車腰彈弓

That was broken long time ago (after 2-3 runs).  Yesterday, I used hot melt glue to glue that area, so the gear box can't 彈, and the 腰 can't twist.....

Result: the car very easy to flip over when you turn.  More importantly, the Co27 motor made the car flip by the head going up too much

I thought about that, and also saw another brother has 4 避震 at the back.  Will try try.  Thanks!
