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.
Bought one of these after owning 10 other protek servos of various models for buggy ST, SC, crawling. I put this 370TBL in my fiances ax10. THE Best and strongest servo I have ever owned....highly recommend this servo.....home run guys
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.
10/25/2108 The hot racing servo horn just bent but the servo is still going strong!!! It’s a beast!
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.
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.
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.
Excellent product. First one I got had the shakes and called amain about it and they replaced it with a new one. This one works awesome, really strong servo.
Thought it was a brute on 6v. Bumped it to 8v. Beast mode!!!
I have both the 170t and 170s already, so I knew I had to get the crawler version for my crawler. These are the o ly servos I'm using going forward. Fast, powerfull and quiet. Cant beat them!!
Bought to and one went out in 2 weeks.. kinda lame for such an expensive servo
Second one went out!
I’ve used protekrc 370tbl for a while now and I like the smoothness and torqck and the reliability of them
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.**
Customer service is wonderful fast turnaround time fast shipping a-1 could expect no less from this first class bussiness by far the best servo I have ever owned unofficially my infraction has done 209mph and this servo kept me going straight with no problems
I got this for my Traxxas Maxx for straight God mode and its mind blowing how strong this Servo is. I love it!!!
The support team in A MAIN is very good, the guys were courteous, professional and easy to work with, I STRONGLY would recommend A MAIN to every one i know!!!! THANKS!!! A+++++
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.
Excellent servo. It made a huge difference in the performance of my crawler, highly recommend.
Put it on my TRX4 with the hobbywing axe 3300kv. It was simple to install. You will need to buy a wire extension to make it work. Do not have anything plastic in the entire steering system. This steering box is extremely powerful and fast. You will break any plastic components. I put a lot of brass weight on my TRX4 and this steering box can still push the truck around while climbing rocks.
