The Arrma Senton 4X4 V3 3S BLX 1/10 RTR Brushless Short Course Truck Extreme offers toughness and outrageous 50+ MPH speed that separates this truck from the pack. Precision aluminum, tough steel and composite materials come together for an easy-to-maintain, super-durable vehicle design that’s now been upgraded to further increase the original Short Course truck’s already impressive performance and durability.

The SENTON 4X4 3S BLX RTR is DESIGNED FAST, DESIGNED TOUGH — built for exciting bashing speeds and extreme, all-terrain durability. Features that enhance its unstoppable performance include a stronger chassis and retained hinge pin plates; steering with more clearance for stones; a castellated slipper pad and sliding gear mesh; and rubber-shielded bearings throughout.

It also now includes a Spektrum SLT3 transmitter and SLR300 receiver. The transmitter is ergonomically designed for long periods of fatigue-free bashing and has a foam wheel for precise fingertip control, plus an improved hand grip and trigger feel. New bashers will be able to set throttle limits at 50% or 75% until they are ready to use the full speed potential. The SLT3 is compatible with Tactic SLT receivers to run other RTR vehicles you may own, and includes a third channel to control optional features such as lights and winches on models that have them.

ARRMA now powers the SENTON 4X4 3S BLX with a brushless system featuring its BLX100 ESC and the Spektrum Firma 3200Kv brushless motor. The combination provides incredible torque, acceleration and speed. The transmission and chassis are ruggedly engineered to take full advantage of the electronics’ power.

It has the ingenious modular design perfected by ARRMA engineers for easy component access and maintenance. The power module, with improved dirt management, consists of the motor with ARRMA heatsink and cooling fan, plus motor plate, slipper clutch assembly and gear cover. The power module can be detached from the chassis as a complete unit by removing just one screw. With the power module removed, the slipper clutch can be reached easily for adjustments by taking out three screws that attach the gear cover. The gear ratio can be finely tuned as the power module now uses a sliding motor mesh design.

A two-piece molding screwed to the truck’s chassis serves as its electronics module, containing a waterproof receiver box, servo mount and ESC tray. The SLR300 receiver mounts inside the receiver box for protection from dirt and moisture. The ultra-compact ESC is screwed to the top of the module, allowing quick access to the on/off switch, while the servo mounts to the side. All three components can be removed together, quickly and easily.

The differential module houses each differential unit in an innovative yoke design. Only eight screws need to be removed to release the front and rear yokes. The power module can then be detached, allowing you to pivot the gearbox cases for differential access. The SENTON 4X4 3S BLX RTR comes brushless-ready with 37T 1.35mod diffs with silicone O-rings. The large gears can withstand huge torque, and internal metal gears have been chosen for reliability during extreme bashing.

Its full-time 4WD transmission uses strong front, rear, and centerline telescopic driveshafts that can’t be lost during heavy impacts, unlike dogbones. A simple, dependable, responsive steering assembly complements the ultra-reliable drive system and features a servo horn with built-in servo saver. The SENTON 4X4 3S BLX RTR includes the waterproof Spektrum SPMS651 metal-geared digital servo for 15% more torque than the previous version’s ADS-7M servo.

The self-bleeding, oil-filled shocks, now with silicone O-rings, use a tried and tested, coil-over design for simple maintenance and amazing handling. Their innovative rod-end has a molded-in spring perch for extra toughness. Extended height dirt defenders and a close-fitting body limit the amount of dirt and debris that can get into the chassis tub. Front and rear bumpers offer defense against impacts.

Tough gunmetal colored, multi-spoke wheels with vented dBoots Fortress SC tires give the 1/10 scale SENTON 4X4 3S BLX RTR Short Course Truck effective traction for bashing on almost any terrain. The aggressively styled Short Course truck body — available in blue/black or red /black— looks great in action and even better up-close, where the attention to detail on the decal and body aesthetics really shines.

This truck is awesome! It’s fast, durable, and fun to drive. I would have to say that this truck and the other Arrma vehicles I have purchased have not disappointed me in any way. Even on 2s power it’s fun and fast. If you want something that is what I would consider one of the all time best RTR vehicles made you should get one of these.

Arrma Senton 4X4 V3 3S BLX 1/10 RTR Brushless Short Course Truck (Red)
Going from a 2wd xl5 Rustler to this is nuts. This truck is so impressive and Arrma I think is giving a hell of a deal for the price. This thing jumps, rolls, takes a beating, and keeps on going. I was torn between this and the Typhon for awhile, and even though I still want a buggy I felt this would be a little more durable.

A few gripes though.

1. The tool they provided could not remove the wheels. First, because it barely fits into the Senton's recessed area where the nut goes and second, because whoever at Arrma put these nuts on cranked them tight! I had to take my traxxas metal 4 way wrench with pliers to get them loose. The Arrma tool cracked after my second attempt.

2. When I first got the truck, it almost seemed to bind up at times. After a few short runs I inspected it with the driveshaft out found the front differential had a spot that would lock and took a bit of force to break it loose. After getting the front diff out I found the "ring gear" had some rough burrs in the plastic teeth. Took some smoothing out with an exacto knife and was much better. It may have broke in after a couple more runs, but it was acting so goofy at low speeds I wanted to investigate.

3. No 1.5mm included. Needed for Hex hubs and spur gear.

4. No stickers! Come on, Arrma. I got a tool box at work I'd be happy to put your name on.

Overall I'd give it 4.9 Stars. The minor issues aside this truck is in no way disappointing.

A lot of truck for the price. Fast with great handling. Well built with a lot of thought to making maintenance easy for the end user. Durable. Will definitely be purchasing more Arrma vehicles in the future.

Arrma Senton 4X4 V3 3S BLX 1/10 RTR Brushless Short Course Truck (Red)
Best bang for your buck and a system that is expandable. I purchased two, one in each color. Before purchasing I looked at several reviews over the versions that have come out. The thing is ridiculous fast. I actually do not start at full power 3s, I start with 2S at 75% power. After a few warm up laps we steadily increase; depending. Many great RC manufacturers and ARRMA is definitely one of the best. I am extremely happy with my purchases. Also,there are loads of aftermarket upgrade and customization parts available. Get one or two and you won't regret it. AMain is on point with customer service and Shipping was fast and free. Thank you AMain, Horizon and most of all ARRMA.

Arrma Senton 4X4 V3 3S BLX 1/10 RTR Brushless Short Course Truck (Red)
great truck for the money. it really does go 50mph with a 3s . freaking nuts. you really need a lot of room to drop the hammer, would prefer to drive this in soccer field .. it does collect lots if debris within the chassis. aka steering servo gets jammed up with rocks. but it pretty much only gets in from donuts or drift turns. love this thing i have two 3s 80c 7500 mah batts for it now! first ran it on 2s 5000mah and i was so disappointed because the run time was so short. its a high powered system for sure!

Arrma Senton 4X4 V3 3S BLX 1/10 RTR Brushless Short Course Truck (Red)
Great car. The price is great. I haven't had any short-corners yet. I decided to take Arrmu, I see no reason to overpay for Traxxas Slash or Tekno. 3S is enough for her. Let's see how the updated servo works. I didn't like the control equipment at all. I didn't like the Spektrum SLR300 receiver, it seems like a cheap thing. Spektrum STX2 is much more interesting.

Arrma Senton 4X4 V3 3S BLX 1/10 RTR Brushless Short Course Truck (Red)
I bought this truck to run in my neighborhood races, the first day of driving it I was thoroughly impressed with the truck. The pinion gear is a little too tall for tighter racing but they use it to hit the advertised 50+ mph. Day 2 driving the truck, 3rd battery pack through the truck the steering servo went out completely. The truck was never bashed or wrecked, the truck stopped turning on a straight away. I tore the truck apart to try and diagnose the issue and all the gears were perfect, all the solders were good (they even cover all the solders with a bondic/ silicone which is cool). I preceded to plug the servo into another truck and it was completely dead. Pretty disappointed to have a truck break on its third battery pack for no rhyme or reason, hopefully replacing the steering servo will be the last of my headaches with this truck for a while.

It works great ordered batteries with it arrived 7 days after the car make sure you order batteries before you know what you want so you can have them together... Or just go to LHS and buy batteries separate.
