Needed to Complete
Born from the full-send spirit of Tomfoolery Motorsports and Cleetus McFarland, the ARRMA FREEDOM FLYER GROM 4X4 RTR Monster Truck rolls in waving the stars and stripes loud and proud. Forged for both newcomers and seasoned bashers, the FREEDOM FLYER GROM packs the raw power and patriotic attitude of a backyard bashing legend, all wrapped up in a compact, take-anywhere frame.
From the moment you crack open the box, the FREEDOM FLYER GROM is ready for a full-throttle celebration. No build, no extra gear. Just charge the battery, pull the trigger, and let freedom rip. The clipless body system makes it easy to access the battery or get back on the road after a crash. There are no pins to lose and no tools required.
Underneath, the reinforced chassis and high-travel suspension are built to take the kind of punishment Cleetus and the Freedom Factory dish out daily. This truck isn't just tough. It's smart. The deep tub chassis keeps out dirt and debris so you can bash harder without clogging the works. The monster truck stance and elevated center of gravity let it conquer every obstacle in its way. Chaos, indoors or out, is where the FREEDOM FLYER GROM feels right at home.
The battery tray uses two catches that swing into place, keeping things simple for new drivers or anyone who wants more time bashing and less time tinkering. Every element is built for relentless, full-send action-worthy of the red, white, and blue it flies. No distractions. No half-sends.
The FREEDOM FLYER GROM isn't just a truck, it's a celebration. Whether it's your first truck or your fiftieth, this mini patriot means business. Compact size. Full-throttle freedom. Bash harder, faster, and longer, wherever you are. Star-spangled monster truck mayhem starts here. Hell yeah, brother.

The Spektrum Smart 2S LiPo battery with IC2 connectors provides the power for long run times. When it's time to recharge, just plug it into the convenient Spektrum Smart G2 S10 USB-C Charger. Safe charging begins automatically and takes only about an hour.

The FREEDOM FLYER GROM 4X4 RTR Monster Truck body snaps onto the chassis easily, quickly, and securely, and comes off with a simple press-and-release. With no tiny clips to force into place, it's a body attachment system that's perfect even for young patriots-in-training.

The SLT2 radio is your full-send command center. While you're tearing it up on 2S, the throttle limiting feature lets you choose how wild your ride gets - 50%, 75%, or full-send freedom. Hand the trigger to a first-timer or grab it yourself and go hell-yeah-brother. Bonus: four AA batteries are included, because we don't do half-sends.

The FREEDOM FLYER GROM 4X4 RTR Monster Truck is engineered and manufactured to the same high standards of durability and performance you expect from any ARRMA vehicle-just smaller. Same big-truck attitude, same full-send energy, ready to rip in your driveway, your living room, or wherever the patch of dirt is calling. Maximum Hell Yeah Brother impact in a take-anywhere size.

The enclosed drivetrain with rugged metal gears carries power from the installed Spektrum 380-Size Brushed Motor to all four wheels for high traction. The entire power system is well-protected for dependable performance on dirt, grass, asphalt, or wherever the freedom calls.

Pop. Drop. Send. Battery swaps on the FREEDOM FLYER GROM 4X4 RTR Monster Truck are fast, simple, and body-free. Just hit the latches, drop in your pack, and you're back on the throttle in no time. No more fumbling. No more half-sends.

The FREEDOM FLYER GROM 4X4 RTR Monster Truck is built to bounce and blast. The all-terrain, oil-filled coilover shocks soak up landings like the Freedom Factory takes a beating. Got uneven ground? Dial in your ride height and gain the clearance you need to send it clean - no scraping, no slowing down.

Built to launch and built to land. The high-angle wheelie bar lets the FREEDOM FLYER GROM carry the front end longer, send it harder, and bring it back down strong. Whether it's your first wheelie or your fiftieth, it's full-send insurance with every pull of the trigger.

That body? Yeah, it's new. And it's loud and proud. The FREEDOM FLYER GROM 4X4 RTR Monster Truck wears its star-spangled colors like a battle flag. It features bold detail, that patented “get out of my way” stance, and built for the cameras looks. Clipless body retention means no pins to lose. And when you do need under the hood, it pops off clean like a flag-waving pro.
