Arrma Outcast 6S BLX vs Losi LMT Grave DiggerWhich Should You Buy?

The Arrma Outcast 6S BLX and Losi LMT Grave Digger are both 1/8 scale, both 4WD, both brushless, and both designed to catch air. But they approach airtime from opposite directions. The Outcast uses raw 6S power to launch off ramps at speed, getting altitude through velocity and inertia. The LMT uses its solid axle design and unique weight distribution to perform controlled wheelies and backflips at lower speeds, getting altitude through mechanical advantage and throttle technique.

Speed separation is clear: 60 mph for the Outcast versus 40 mph for the LMT. That's a 50% speed advantage for the Outcast, which is enormous. The Outcast's 6S power system produces acceleration that pins the truck to the ground before launching it skyward off any ramp or natural jump. The LMT's 3S system is gentler but purposeful, delivering power in a way that's optimized for throttle-controlled stunts rather than flat-out speed. You don't need 60 mph to do a backflip, and the LMT proves it every session.

Dimensions favor the LMT in footprint. At 22.84 inches long and 17.52 inches wide with 3.54 inches of ground clearance, the Grave Digger is longer, wider, and sits higher than the Outcast's 21.46-inch length, 16.14-inch width, and 2.17-inch clearance. The LMT's enormous ground clearance comes from its monster truck-style body and massive tires that look like miniature versions of the real thing. Weight is similar at 11.13 lbs for the LMT and 10.58 lbs for the Outcast, so neither truck has a significant mass advantage during crashes or landings.

Waterproofing is a significant differentiator that affects every driving session. The Outcast is fully waterproof and will run through puddles, mud, wet grass, and light rain without any concern. The LMT Grave Digger is not waterproof. For a truck at this price, this omission limits where and when you can drive. Morning dew on grass, a surprise rain shower, a puddle you didn't see, any of these can damage the LMT's electronics. Aftermarket waterproofing solutions exist but add a modest amount to your investment and require some wrenching.

The LMT's solid axle design is what makes it irreplaceable in the lineup. No independent-suspension truck, including the Outcast, can replicate the LMT's ability to do on-demand wheelies and consistent, controllable backflips. The solid axles allow the chassis to rotate around its center of mass in ways that independent suspension physically prevents. It's a completely different and incredibly entertaining driving experience that never gets old. If you've ever watched Monster Jam and wanted to replicate those moves, only the LMT offers that experience in RC form.

Battery costs strongly favor the LMT since it runs 3S versus the Outcast's 6S. You'll spend roughly half as much on batteries per session, and over a year of driving, that difference could total a significant amount. The LMT accommodates 5000mAh 3S packs for solid runtime. The Outcast needs 5000mAh 6S packs at roughly double the price. Both trucks have good parts support. Arrma and Losi are both distributed through Horizon Hobby, so parts ordering goes through the same system.

The Outcast at its mid-range price is the more capable, more powerful, more weather-resistant truck. It can bash, jump, stunt, and run in any conditions. The LMT at its mid-range price is the cheaper, more specialized option that does monster jam tricks better than anything else available. Your driving style and preferences determine the winner here, not the spec sheet.
