Losi TENACITY 1/10 RTR 4WD Brushless Monster Truck (Blue)
I've had this truck for several months and have been driving it hard on a regular basis. It's one of my favorite bashing vehicles in my fleet. I beat on it pretty hard, and I have yet to break anything except the body and the plastic shock caps. The truck is really, really tough for its size and price. The electronics are good --- the stock ESC/motor combination are very powerful. On 3S power, the truck rips hard. I normally have to drive it on the Medium power setting so I can actually control it.

There are only two downsides to this truck: the plastic shock caps and the motor overheating. You have to replace the plastic shock caps with metal ones if you want to avoid breakage. This is not an expensive repair, and you only have to do it once. The caps won't break again after that. You can buy cheap motor fans here on Amain to deal with the overheating issue. I like the Wild Turbo Fan fans. I have one on my Tenacity right now, and it works like a charm. No more overheating.

I've heard some folks complain about the price of this truck. While I think it's pricey for the type of vehicle it is, I also think you get a lot of vehicle for the price. Vehicles like the Traxxas Stampede 4x4 are even more expensive and require a lot more upgrades.

I think this truck deserves close to 5 stars, maybe 4.5 stars. I'm only giving it 4 stars because it needs some upgrades right off the bat.
