ProTek RC 1KTBL High Torque Brushless Crawler Servo
The ProTek 1KTBL was developed to satisfy the needs of torque thirsty enthusiasts. With the ability to deliver over 1000 oz-in of torque and .11 transit speeds at 8.4V, there aren't many servo options that can compete. Competition rigs, heavy scalers and bashers can take advantage of what the 1KTBL delivers. Even large scale surface models and airplanes can benefit from the insane torque the 1KTBL can produce.
All this power means nothing without durability - and the Protek 1KTBL punches far outside its weight class. This servo offers the power, reliability and durability needed to keep the competition on the ropes. The proven gasket system allows waterproof protection up to 1-meter, so it will go the distance in any condition. A full steel gear train, 25T output shaft and full aluminum machined heat sink case finish off the package to create a tough servo that is perfect for demanding applications. The 1KTBL delivers power in excess - with the durability and reliability that make ProTek R/C servos a an easy choice for enthusiasts that expect the most from their rigs.
"The ProTek 1KTBL is very impressive. It is strong, reliable, and durable enough to take on any course. I put the 1KTBL through rigorous testing and I will definitely be upgrading my entire crawling fleet with this ProTek servo!"
Ben "Toyzuki" Moren, ProTek R/C Team Driver
NOTE:
- For best results, and peak performance, we recommend you power this servo with a BEC.
- If you experience glitching or poor performance while using a Futaba transmitter, you must turn off BLS mode. BLS mode is only compatible with Futaba BLS type servos.
- Requires a servo extension lead for a drop-in TRX-4 fit.

First rock crawler, more for scale and learn about rock crawling. Element Trailrunner, Nice truck by the way!
I had updated the radio to a Spektrum DX5 Rugged and receiver. Running the Warn Winch which I made a custom mount to mount over the steering servo plate, this too was changed out for the BowHouse aluminum plate replacing the factory plastic.
Ive updated the steering setup to Bowhpuse and have Brass bits around the car and updated 1.9 wheels and proline predator compound tires. Still running Factory brushed Team Associated motor and ESC.
So with this setup without external BEC I am supplying 6V to the steering servo and also the Warn winch.
ok focus on the steering servo, way better than the stock although nothing was wrong with the factory servo this servo provides much more reaction, fast and crisp steering. Also holds the tire positions much better than stock! The difference is immediately noticed and appreciated. I figure if I updated the steering plate to aluminum and using BowHouse updated steering components might as well improve the servo and take advantage of the updated receiver output of 6V. So with 6V the servo is suppoed to output 55 oz in of torque so that's 55 pounds. I think I am good with that but there is a temptation to try a castle BEC and feed 7.1 volts directly to the steering servo. I'm not sure I will do this yet.
Overall its a great servo and will look to use this in other cars!
Amendment to the above, a month later:
I finally put a multimeter to my AE supplied ESC and the voltage is 7.4v to the steering servo. All this time I saw the 3 star review and thought I was also running 6 volts but my steering servo is wicked strong and responsive ....turns out its running on 7.4. Very happy with this steering servo one month later and it is not a light truck.
Additional comment: 1/5/2024 - I recently purchased another set of these servos for use in the Tamiya Dual Rider trike which leans the chassis side to side to steer the vehicle. I've seen many built examples of these RCs which have a wobble which I suspected was due to weak servos. I have just completed a build of this RC and used this servos, it has no wobble and the servo easily leans the trike from side to side and holds the position easily. Great servo and easily allows this RC to perform at it's best.
AMain Hobbies Note: The BEC inside the UDR is only capable of 6.0V. For maximum servo speed and torque, a BEC that can output 8.4V is required.
