E Revo 2.0 Two Servos Vs One

[@jeffwilliams409]

Good comparison. Been bashing my erevo for over a year now. Other than swapping to metal gears the stock servos work great. If and when they go bad I'm going to stay stock. Upgrades aren't always better.

[@tylerfengler7576]

youre gunna regret buying stock servos again when you couldve upgraded for not a lot more. stock servos on the erevo are trash

[@rcyalater...2305]

I concur, most Traxxas servos aren't great.

[@MatrixRC]

I run one savox waterproof servo and I adjusted the steering and it moves really fast. I have it on my channel just take a look.

[@Hycinex]

Nice video. I hope you also disconnected the linkage under the car as well, this will make a difference to steering strength as it wouldn't be carrying the dead weight of the other servo disconnected. I run 1 servo on my 3.3 revo with 3.8" trencher HPs.

[@stevenmaness5153]

I bet he didn't.

[@dylanwhite6539]

I ran a ecopower 110t which has 280oz and no issues for about a month before I finally got my 120t and I felt like it was just as good as stock. Although admittedly the stiffer spring was probably needed. I won’t be going back to duals that’s for sure.

[@outsourcedrc]

I tried a single servo on my V1 E Revo and you can clearly see the body twist from having only one. I can only imagine its doing the same thing on the 2.0.

[@DieselBadger60]

Really awesome comparison video!

[@Critter0817]

The servos on my E Revo have lasted at least 11 years. They're stock, and pretty weak. I'm looking to get a new set, hence why I'm here

[@umtpz]

Critter0817 mine are still working :/

[@cryptolife5055]

[@RCsBigAir]

I love your videos, great info, and I love your research.

[@outsourcedrc]

Thank you!

[@KTMcaptain]

I agree with running two, simply because of how hot both my servos get, but traxxas runs 2 cheapo servos instead of 1 nice servo to save money and get you to buy hop-up parts later on. They even advertise the 330oz blue 2250 servo as replacing both stock erevo servos as a single unit. "Replace the E-Revo's dual servos with a single #2250 for lighter weight, more torque, and lightning-quick steering response."

[@BBradCO]

Thank you, this was a very helpful video!

[@outsourcedrc]

No Problem!

[@dylanwhite6539]

No, there’s no reason for Dual servos. Your issue here is the size of the tires, possibly your lack of stiffer servo saver. Traxxas does recommend using a single servo with the ERevo 2.0 with that stiffer spring with their 330oz and 400oz servos.

[@ralphs9531]

I think it comes down to physics, with 2 servos one is pulling while the other pushes.

[@general_ahab]

RwSbach bit the wheel size is different

[@gadgetmantwincities]

Great comparison.

I think most people run one monster torgue savox 1230. that's what m doing. it saves me some money. hopefully it works fund. good video sir

[@outsourcedrc]

I saw one guy say that he had two of those 1230's and with just one he could tell a difference. I'm curious to how one 1230 compares to two 1256's.

[@msn1206]

I have been through 2 sets of stock servos from Traxxas. It really is a pain to keep changing them all the time. I even put my stock servos from the old E Revo Brushless in my 2.0 and it appeared they were weaker than the stock 2.0 servos. So I was going to run just 1 powerful servo in the 2.0 but now I'm going to run 2. Do the Savox servos make a hum sound when they are in the neutral position, i have heard digital servos do that and it is normal to hear them make noise.

[@outsourcedrc]

Yes they hum. It's not too bad. You can hear them in my latest video when I am looking at the rear of the E Revo. After talking to people, I believe two servos are better than one big servo.

[@revo2757]

@@Shadows-RC On the reciever, there are two channel 1 (or 2) slots, so you can plug in 2 Servos (or whatever)

[@taevy12]

sir, you are right. I installed savox 1230 single setup on mine. It's slower and weaker than stock. I can't believe it. on paper the savox 1230 (499 oz of torgue) should destroy my stock dual servo. i am going back to dual setup.

[@outsourcedrc]

Yep. That's what I hear.

[@jeffwilliams409]

Keep in mind your turning a larger mass with the 2.0

[@L42776]

Nice vid, both of the servos on mine shorted out I think. Guess it’s time for an upgrade!

[@timsgta]

I aligned them and do not use tsm, I'll use it a little when my single stronger servo comes in.

[@ander8329]

The best Chanel

[@danielbourdeaux]

The single servo on the 2.0 probably works just as good and as fast as the old revo. but it has bigger tires to turn and a dead servo to turn also compared to the old revo.

[@timsgta]

I aligned my servos and turned off tsm, no problems so far...

[@timsgta]

@Sheist MCE I have since went with a single high torque metal gear waterproof servo, and it's better than the two stock ones, imo...

[@timsgta]

@Sheist MCE you bet

[@hobbycow5346]

Informative video, but I found the comments even more informative. It sounds like a BEC would change your results that you had in this video. Have you ever tried a comparison between one servo with a BEC and without? I'd love to see that and learn even more...

[@outsourcedrc]

I dont want to run a BEC. I dont see a reason to. I understand what it does, it just isnt needed.

[@hobbycow5346]

Understood. I just bought an ANNIMOX All metal gear $25 servo from amazon. Boasts 25 kg/cm which transfers to 347oz in torque with an operating range of 4.8-6.8v. Should run fine without a BEC. But that's my back up plan. I first plan to mechanically sync the stock servos as best as possible, and see how long they last.

[@MrAttitude16e]

I’m running 2 1230sg savox servos on my 2.0 even with 500oz of torque on one servo it still turns better with 2

[@outsourcedrc]

That's what I would assume. I think the Traxxas engineers knew what they were doing when they put two servos on that E Revo.

[@wegoallout.v2505]

I'm glad that I seen your comment because I will receive my e revo 2.0 Wednesday and I'll don't plan on using the traxxas servos bought the 1230 sg it's good to know

[@MrAttitude16e]

Make sure to get the heavy duty servo saver spring you will need it, with 2 1230sg it compresses the heavy duty spring like the stock servos compress the stock spring

[@iftibashir]

Isn’t 2 savox 1230 servos major overkill? Would an external BEC be needed to run two units?

[@andyvannort2743]

@@iftibashir the vlx6 esc can handle 2 6v servos up to 20amps. Should be plenty for 2 savox

[@drog343]

Is that with the stock plastic steering assembly, because that thing has a lot of flex. I think with an aluminum steering assembly the difference might not have been as much. I run a single 1230, but have the aluminum steering assembly (1/0 Summit, which is comparable in this regard).

[@outsourcedrc]

Yeah it's the stock

[@drog343]

Yeah, because I noted the same thing in mine when I first went to a single servo, especially when it had twice as much torque as the 2 stock, but I didn't actually see much benefit until putting a aluminum assembly, it's faster regardless of the amount of resistance. The stock plastic part just bows really bad, so you need both servo's one pulling one side while the other pushes, it allows the plastic part to turn relatively straight (instead of just bending when one servo is pushing and pulling on just one side).

[@ABRsanta]

hi, Do you have a Part # for that ? or a name or an Amazon link... thx

[@drog343]

@@ABRsanta The part I have is, HR RVO3808 Silver Aluminum Steering Assembly (just double check that it is compatible with the 2.0 version, as I'm just going under the assumption, that this was a part that wasn't changed).

[@Cc-nj2zm]

Why do people keep trying to just do 1 servo when it was designed for 2?

[@V8chump]

One of these servos is MUCH better than 2 stock servos on the e revo 2.0. Think the tire size and maybe a little weight threw the comparison off, old revo has much lighter, slightly smaller tires.

[@MrRmalimata]

[@borgfpv8418]

Great video, super explanatory! Question, did these Savox fit into 2.0 normally or did you have to do some sort of adaptation? I'm thinking of putting in my e-Revo too ... Another thing, I prefer to use two servos because it distributes the force of the crashes in two arms of the servo saver and not just one ...

[@general_ahab]

bigger wheels on the e-revo 2.0

[@Cc-nj2zm]

Your so informative. Thanks. Are the orange stronger servo’s waterproof?

[@outsourcedrc]

Nope. The waterproof servos are blue. The waterproof version of these are the 1210 servos

[@bigbadbronx72]

Quick question. What is the BEC on the ESC? If those are high voltage 7.4 servos, and running only one the ESC's BEC voltage being lower than the servo can use, ie; a 5v BEC ESC limit running a 7.4v servo, it won't be at full strength. I'm sure you figured this in, just asking because I'm most likely going to get an E-Revo 2.0 VXL this winter. Thanks and great video!

[@outsourcedrc]

I forget what the BEC is stock. I'm aware that they are not at full power. I don't think they really need to be. I assume that running the servos at full power will drain the batteries faster, and Savox servos already drain batteries pretty quickly. When I put these on I was going to put a BEC on it, but after I drove it around I didn't think it needed it. I may get one and test the battery life after installing. I know these servos as they are shortened the run time by like 15-20 minutes.

[@bigbadbronx72]

@@outsourcedrcI have to disagree on the shortened run time. One servo operating at it's full 7.4v will steer the truck 100% better and only shorten your run times slightly. Try it out!😀

[@jimhimesjr]

bigbadbronx72 agreed. One servo running at 7.4 should be using less battery then 2 running at 5 or 6 volts each. Savox servos are power hungry but 15 minutes less run time seems like a bit much, they aren’t like a motor that is working constantly. Good video, interesting comparison.

[@outsourcedrc]

@@jimhimesjr I didnt do a battery life comparison on the E Revo 2.0, but I know before I swapped the servos the 2.0 would run out of battery about 5 mins before the V1 E Revo, and now its like15+ mins before the V1. Its pretty consistant.

The other servo was never dead weight. I disconnected it.

[@jamesstubbs8954]

I believe if you had purchased the Savox 1230SG instead you would be just fine running a single servo setup. The 1230SG is 500 oz torque @ 6v so it's pretty close to what you have their between the two Savox 1256's. Also, did you change your servo saver spring over to the heavy-duty one that Traxxas offers for the E Revo 2 when you upgrade to metal gear servos?

[@outsourcedrc]

I did not change the server saver spring. I've had zero issues out of the servos or the saver so far.
