The Ultimate Compact Crawler Solution

The Spektrum Firma Sensored 2-in-1 System is specifically engineered to be used with 10th scale Crawlers and Scalers. Featuring advanced Field-orientated Control (FOC) and professional drag brake performance and torque control, all while being fully waterproof.

The compact 2-in-1 design grants builders the ability to reduce clutter and components, giving you the most room for scale accessories and customization. The integrated design makes the size similar to a 550 can size motor, making it a easy drop-in option for most 1/10 scale crawler, scaler and trailer models.

Available in a low speed 1400Kv option for extreme slow speed and high angle of attack performance. And a high speed 2300Kv for excellent control for trailers and rock bouncers.

Field-oriented Control

The Spektrum Firma Sensored 2-in-1 System features a high-precision magnetic encoder and rotor position sensor that provides excellent 1 to 1 control feel when driving at any speed and at any angle. Perfectly suited for trail driving, rock crawling competitions and rock racing setups. This advancement in sensored motor control allows the ESC to match your throttle input to the motors RPM with unmatched precision.

 

Intelligent Speed And Torque Control

The Spektrum Firma Sensored 2-in-1 System provides a closed loop control, ensuring that the esc maintains torque and RPM levels even as driving conditions change. Giving unprecedented control when driving uphill or downhill and even when in wet or loose traction conditions. No matter the terrain, the Spektrum Firma Crawler system keeps you in complete control.

 

Maximum Power Efficiency Provides Longer Battery Life

When driving with the Spektrum Firma Sensored 2-in-1 System, drivers are better equipped for the long trails ahead. The Spektrum Firma Sensored 2-in-1 System only uses the power it needs to match your desired throttle output, providing substantially more efficient current levels and extremely long battery life when compared with similar sensorless systems.

 

Pro-Level Drag Brake Adjustment

The Spektrum Firma Sensored 2-in-1 System features a huge range of drag brake adjustability, allowing for drivers to expertly tune their crawlers and scalers depending on their driven train and vehicle weight. Allowing up to 200% drag power, no matter the setup, the Spektrum Firma Sensored 2-in-1 System can keep your vehicle parked at nearly any incline.

 

Waterproof

The all-weather, waterproof design of Spektrum Firma ESCs allows them to perform in nearly any terrain under almost any conditions. Firma ESCs keep you going through dust, gravel, snow, and water.

 

High-adjustability Programming Options

Using the Spektrum ESC Programming Box (version V2 required) , you can easily change settings on the trail to suit driving conditions. An easy-to-use Smart Link USB Updating and PC Programmer app is also available.

Comfort, support, style, and durability in this chair!
Color: Lightbrown, Color: Lightbrown
🥰 Very sturdy and durable for everyday use in the office or at home! Perfect for sitting, planking, criss-cross Apple sauce, or whatever seating position you wanna call it lol. 🛠️ Assembly; All the tools you need are provided in this kit! This took me all of 20 minutes to complete. Once you read the instructions, it’s pretty much placing screws in holes and done! No drilling needed! Cheers to the quick and easy process! Material is easy to clean, for keeping it in pristine condition! 🌟 Softness; Very nice and plush backing! Sides come down just as advertised but requires a bit of force to do so which is perfect, as they aren’t just plopping down because you press on the arms. I was concerned that would be an issue, and it’s nothing to worry about! Absolutely Love it, well designed for comfort / support, style, and adaptability! ✅ Stability; Chair wheels glide as expected on my carpeted floor. Pretty much with ease on the tile surface. The chair feels sturdy, even with the adjustable height and backspring, ultimately a relaxing desk chair. I appreciate there not a lot of wobble and no noise when moving around.. I’m not getting wild here but you could totally plank on the chair if you wanted and it still remain stable! 👍✨ Overall, I would definitely recommend! Storage side pockets are a plus!

Stylish, comfortable, and very practical
Color: Black, Color: Black
This chair is both cuteand funtional. The wide seat is super comfortable, especially for sitting cross-legged, and the flip-up arms are really convenient. I also like the side pockets for small items. It rolls smoothly, feels sturdy, and was easy to asssemble. Perfect for a home office or vanity setup.

Nice office chair
Color: Beige
I recently purchased this chair for my home office setup. This chair is very comfortable and feels sturdy right out of the box. The seat cushion is thick and supportive, the back provides good support. I really like the flip-up armrests, which make it easy to slide the chair under my desk. Assembly was simple and didn't take long. Overall, it's a solid, well-built chair and a great value for the price.

Seat width short (Not tall people friendly) Very nice otherwise.
Color: Beige
I like the chair a lot. It’s very sleek and modern. One problem I have with it tho is the width of the seat. I am 5’9 and not necessarily a petite woman and when I do sit cross cross I seem to hang off the front. I do like that I can sit cross cross even with the sides of the chair up but the fact that I hang off the front is a bit annoying. There are plenty of other ways to sit on it tho and being able to maneuver it to where I can sit different ways is nice. I would say that this chair isn’t exactly tall people friendly. Also pay attention to the height and width of your desk because it isn’t exactly universal to fit under a normal desk. It is also super easy to put together and instructions are clear. Also as expected the back of the seat is a bit short and personally for me I like that a lot but word of caution for others that want the back of the chair to go up their entire back. I like it shorter because I’m able to sit sideways and have one side of the chair up and the other down and using the back rest as an arm rest. I did just buy it and am slightly concerned for it to not last purely because the manual said not to use it if it squeaked of creaked and it does both of those things. But I will still be using it until it breaks or it’s life span ends. It also seems very easy to clean the crevices are very short and you are able to wipe things out with ease.

Really comfortable upgrade from my old desk chair
Color: Beige
My old desk chair had been getting pretty uncomfortable, so I decided to replace it with this white one. After using it for a few days, I can definitely say it’s been a really nice upgrade for my workspace. My old chair was starting to feel stiff and uncomfortable after sitting for a while. This one is a lot wider and softer, which I really appreciate. Sometimes I sit cross-legged when I’m working on my laptop, and this chair actually has enough space to do that comfortably. The flip-up arms are also really practical. When I’m not using them, I just flip them up and push the chair under my desk. My workspace feels a lot less cramped now. The wheels roll smoothly and the height adjustment was easy to set up. I also didn’t expect to use the side pockets much, but I’ve been keeping a notebook and my tablet there, which is actually pretty convenient. I mainly bought the white color because I wanted something simple for my home office, and it looks really clean in the room. After switching from my old chair, working at my desk has been a lot more comfortable. It’s been great for longer work sessions, and overall I’m really happy I decided to get this one.
