ProTek RC 370TBL Black Label High Torque Brushless Crawler Servo

The ProTek 370TBL was developed specifically for crawler applications. Heavy 2.2 class rigs, U4 racers, lightweight 1.9 comp builds, and ultra detailed scalers can all benefit from the feature set that the 370TBL delivers. Pushing over 650 oz-in of stump-pulling torque and .13 speed at 7.4V, the 370TBL will move heavy 2.2 tires with ease - no matter how much weight you put in them.

All this power means nothing without durability. By combining this incredible power with a specialized gasket system, the 370TBL is waterproof up to 1-meter and will stand up to anything mother nature can throw at it. A full steel gear train, 25T output shaft and full aluminum machined heat sink case make the 370TBL extremely tough. The 370TBL delivers the excessive power that crawlers demand - with durability and reliability that make it a must have servo for crawlers that expect the most from their rigs.   

 

NOTE:

  • During testing, we found that some Tactic receivers included with the SCX10 II RTR do not communicate well with high performance servos, and may not function properly with this servo.
  • For best results, and the 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.

ProTek RC 370TBL "Black Label" Waterproof High Torque Brushless Crawler Servo
WOW! hard to believe there were bad reviews on this servo. This thing is a beast. I ran over 2200 gates at Axialfest with this in my scx10ii and it could literally push my rig around. I then ran about 400 + gates with my 11.4 pound 2.2 custom Wroncho build. Again, it had enough power to toss the rig around when bound against a rock. I will warn you though if you don't have metal everything that is attached to this servo the servo will destroy it. Plastic steering link, servo horns, knuckles or chubs will be ruined behind this much power. I heard there were some issues with the first release but they definitely have the bugs worked out. I own two and plan on running them in my rigs for now on.

ProTek RC 370TBL "Black Label" Waterproof High Torque Brushless Crawler Servo
Ok after busting up 3 servos on my Wraith I pucheased this one and I have to say well worth the money! I have Castle Creations Mamba X with 2850KV motor running 4S Lipo it tops out about 30MPH and I have hit many objects busting rod ends and steering links and this servo is still running on the original set of gears without a servo saver! When I run on trails I use a 3S Lipo and this servo has monster torque! Don’t be a fool like me and waste $$ on cheaper servos buy this one! Also I did cross a creek with my Wraith and the servo was under water and the servo survived.

***UPDATE***
10/25/2108 The hot racing servo horn just bent but the servo is still going strong!!! It’s a beast!

ProTek RC 370TBL "Black Label" Waterproof High Torque Brushless Crawler Servo
My experience with this servo has been great so far on a medium weight TRX-4, with Hobbywing AXE FOC R2 3300kv motor and speed control combo, on ProTek 1800mah 3s LiHV batteries, controlled by a Spektrum DX5C transmitter/receiver. The server performs well whether on 6 or 7.4 volts. All of my steering linkages and cups are stock so I can't say whether or not it will destroy those, but it is very powerful.

The servo itself is of very high build quality. It's solid aluminum and looks great - I also had to purchase a 25t aluminum servo horn, and a servo extension wire to reach my receiver on a TRX-4 (item KOP36520). It is much quieter and way faster in operation than the stock Traxxas steering servo. I had no issues mounting it to the TRX-4 using the same stock hardware. If I had to build another truck, I'd buy this again for certain.

Works well in my TRX4.

One thing to note: the power lead is WAY too short for the TRX4. You'll either need to flip the receiver box around or buy an extension cable to make it work (I did both).

I ran this servo during 12 hour event at The Pro-Line Fix Enduro and it stayed strong, cool and never a hiccup all day long in the brutal conditions of the High Desert near Apple Valley, CA. I'm very happy and proud to say the 370TBL is now Recon G6 Certified!!! I have finally found the steering servo for me and the harsh conditions that I put my rig through on a regular basis. Thank You. ;)

On a scale from 1-10 I would give this a 12+.

I bought this when it first came out and that night I used it to push a garden brick across the table. It pushed with such force it actually pushed it away from the servo. I have it in my Beast II and it is a monster. It has been fully submerged in mud and still works like a champ. Will recommend to all my crawling buddies.

I set this servo up on a RTR SCX 10ii Honcho, BEC set at 6 volts, vanquish 25T servo horn. Works flawlessly. I also shimmed the servo with 4 1mm ball cup spacers made by ProTek. Lifting the servo by 1mm allowed for no binding. I have about 3 hours on this setup and am very happy.

I have 2 e revo 2.0’s. Both the factory servos broke within 5 batteries. I put 2 of these in each car. Figured it would evenly distribute the stress loads better then 1. The cables are JUST long enough to not need an extender. The torque is very high. Visually they seem faster when put right in front of the stock truck. It does feel a smidge more responsive. I am not using any BEC, just directly to the factory ESC. I have about 15 batteries ran through and no breakage yet or any complaints. **DO NOT purchase the HD spring if putting on an e revo. Its too much force and it will just cause all the steering components to break.**

Eh… I bought a new Xmaxx from AMAIN…. After I wrecked my 1st Xmaxxx. I really like AMAIN, but this servo isn’t much of an upgrade. The stock servo is working snappy and just fine compared to this one I bought to fix the wrecked truck. IMO, not much of an “upgrade”. I’ll buy another servo from AMAIN, absolute 1st rate sight. But as for this servo, not much of an “upgrade” to stock. Keep looking IMO.

Excellent MT servo. I have one in my Savage and one in my TLR LMT. One came with a little play in the spline, Amain replaced it with another one immediately! Go to big torque servo.

This servo about throws the huge wheels on my HPI Savage XL off. I have jumped this 20+ pound beast over 20 foot doubles and it keeps asking for more. I was going to put a ptk-170TBL for the steering servo since I have on in my TLR nitro buggy and it is top of the line, but upon recommendation from the Amain Hobbies crew I chose the 370TBL instead. Same specs as the 170TBL, but then it is waterproof. Not a bad little extra for the same price. I am going to be buying another three, one each for the two other savage xl's I have built as well as a TLR truggy I just got done rebuilding.
