No denying that this car is fast. I can stay with 1/8 scale guys with this car. But there are things I can't STAND about it. Here they are:
- It is belt driven, and hasn't shown it can handle the same drive loads as a shaft/gear driven car.
- The whole chassis layout looks like a yard sale.
- Upgrades are scarce (in USA), and front LCD's by Losi are small fortunes.
- The aluminum brace for the rear hinge pins. Almost ten years later and Losi never even tried to fix it, even though they knew it sucks.
- Every bearing surface is exposed to open air. This means one good ripping in the dust and you have hours of cleaning to be done. AE stealth trannies are nicely sealed, but not the xx-4! All bearings for the steering are like dinner plates, holding mud and dirt for your XX-4's steering assembly as you drive it.
- Dirt easily finds its way into the diff area, hastening wear.
- Motor has little open space, so you can easily smoke a motor if you are running on low grass, for example. Temps get high around the motor, and it can cost you.
Feel free to add to this list!
