How To Set your Servo Endpoints & Why it Matters - For Arrma & Traxxas TQi 

Hey me too just got a 5t2.0 few weeks ago waiting for my Futaba 7PXR to come in! This is my first 1/5 scale so just like you I'm watching endless videos to try and learn as much as I can. Do you plan on any upgrades and if so what kind?

Excellent. Happy the video helped William. -Brett

Perfect timing would have been before you’ve ruined them.

@@billybobbobson5346 stock servos went out they are set up perfect

That’s how I’ve done it

Same bro

Same

Yup

Thanks for the tip!😁

Greetings! -Brett

Or you can get the Bluetooth module and download the Traxxas link app and eliminate the buttons also get the Traxxas phone mount you

You can set your end points and everything else in the app and there’s a lot more to the app

Thanks Mar, you too. -Brett

Good call. A good programmable aftermarket transmitter is priceless and can be used with all your future vehicles. What transmitters did you get? -Brett

@@AMain_Hobbies I actually went for the under dog... FlySky Nobel. And oh my goodness am I impressed. My entire fleet is tied to it and the response, the range, the fine running, and the features are amazing! Well worth the investment in my opinion. Its even set up for boats on a separate setting!!! Highly recommend!!! But be prepared to shell out $260 for the transmitter and $40/ receiver.

Great tip! Thanks for adding that. -Brett

@@AMain_Hobbies will you be doing the wishlist thing this year too?

@@jasonbell2733 I don't know for sure but probably. -Brett

So dont do it like this then..(felony) I upgraded my servo and its stressing..

Hmm, never tried that. Since the transmitter is saving those settings, they should still be correct the next time you add your receiver and rebind it to the transmitter, but I don't know. It might not work correctly, it's tough to say. You might have to try it out. When you remove the receiver and add it to a new model, be sure to use a new model profile on your transmitter so you don't overwrite the old settings. Let me know what you find out. -Brett

@@AMain_Hobbies Thanks a lot, very helpful! 👍

I don't think they do, although i'm not that familiar with those transmitters. -Brett

@@AMain_Hobbies Thanks. Is there any way to do it on transmitters that are like this, or do you have to buy another transmitter and does the Flysky GT3C have EPA or an EPA like setting to set servo EPA.

Hey Daniel. How would you describe the binding? With the truck on the flat ground, are the tires turning? Sometimes a rock or debris can get wedged in the steering linkage causing issues. -Brett

Yeah, the Traxxas Link makes these adjustments super easy. It's a great device to have and one of three items in our 3 Must Have's for Traxxas: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-_wegSAKX-3A.html -Brett

It's hard to say, some servos are just noisy. But if it's still noisy when there is no load on it, then that's just the way it is. -Brett

The case doesn't seem to be getting warm or anything so maybe it'll just run this way for a long life LoL. It was among the cheapest Hitec has to offer and still seems stronger and is definitely faster than the stock RTR digital servo it replaced. Can't hear a thing once the nitro engines fired up XD so I'm just gonna send it. Thanks for your reassurance! and all the parts and supplies!

Those vehicles are designed to have more steering angle than an average vehicle, but the end points still need to be set. -Brett

Do your best to avoid using 100% steering throw. Other than that, you could upgrade your transmitter. -Brett

Hmm, not sure about that Michael. When you say the brake percentage is all the way up, is that on the transmitter or the ESC? -Brett

@@AMain_Hobbies hiya Brett thanks for the reply...both are turned up well the end points on the controller and the brake percentage on the esc...can only set it to 50% for some reason in those....its baffled me so I think I'm just going to get another max 6 and I'm not sure whether to get an ezrun 4274 2200kv or a xerun 2250kv, which would you favour over those 2 please...looking for speed and low temps

@@mickyovts3872 For just bashing around, probably the EZRun because it's less expensive yet still high quality. If you are racing the Xerun would be the better option. Hope that helps! -Brett

I'd look elsewhere for an issue; maybe the steering assembly is bound; maybe the servo saver is worn out; maybe it's just a limitation of the car? What car is it? What servo is it? What type of servo saver is it? Did you add any other steering or front suspension upgrades? -Brett

@@AMain_Hobbies I know the steering rack is worn out and probably should be replaced to reduce play but there is no binding. I think the servo saver is the problem now that you mention it. The servo is a cheap E-Bay special ( FeeTech 35KG )and I have the same ones in my Typhon and Granite. Maybe I should remove the servo and check the travel. It just seems like the AMP never did have a good turning radius compared to something like my DR-10. I totally appreciate you helping me out and feel honored that someone from such a well know company would take the time to answer my question. 💯💯

Usually the knob is not centered because the servo is usually off center a little from where the vehicle is. You can't reset steering trim per say, but you can adjust sub trim, which is like a more precise trim to use, before the actual steering trim. Go to 5:34 in the video and look at the program tree, and notice directly above the end points, is sub trim. Hows the servo saver in your vehicle? Sometimes when they start to wear down, the steering gets sloppy and doesn't center. When driving, it feels like the car just steers where it wants to, like "wandery". -Brett

@@AMain_Hobbies thanks for the reply. I'm kinda new to the sport. So what does the sub trim do? I did what the traxxas manual says and I'm not seeing any changes.

Hey, you're welcome@@jadebylund7061. Here is an explanation copied from the TQi manual: The Sub-Trim function is used to precisely set the neutral point of the steering or throttle servo in the event that simply setting the trim knob to “zero” does not completely center the servo. When selected, Sub-Trim allows finer adjustment to the servo output shaft's position for precise setting of the neutral point. This might help you center up the servo without maxing out the knob on your transmitter. What vehicle do you have? -Brett

@@AMain_Hobbies is on a rustler 4x4 vxl. I just changed the servo out after the original died. I've had it 3 months now and the servo savers still seem okay.

Is the servo moving, like it's trying, or is it completely unresponsive? Is the servo wire seated into the electronic board ok? -Brett

@@AMain_Hobbies so i have two hbx rc’s. One rc is completly unresponsive. No movement at all when it comes to steering. The other rc is responsive, the servo is moving but its like restricted and it cannot turn the wheels. Both rc are ok when it comes to the throttle. They can run forwards and backwards

Our best estimate is July 7th. -Brett

@@AMain_Hobbies OK thanks! I actually just ordered one about an hour ago from AMain!

@@jondoe6618 Awesome man! -Brett

@@AMain_Hobbies I support my local rc shop when I can.But when I can't AMain is where I always look. Next on my list is a axe 3300 system for my trx4 sport!

You'll want to center the steering so the truck goes straight before you set the EPA's. When installing a new servo, you'll want to completely center the servo when you add the servo horn. Sometimes I'll put a horn on the servo and turn it untill I see where the horn needs to be, and then adjust by picking up the horn and reinstalling. Once i'm good, screw on the horn. You can also turn on the model and let the servo center (but be sure to set steering trim to 0 for this). Once you get the servo installed, turn on the model and center the steering with the trim knob so the truck drives straight, then set your EPA's. Hope that helps Donnie! -Brett

@@AMain_Hobbies Brett I think in understand, I will take a try at it tonight and if I get stuck I will message you back. But sounds straight forward but we will see if I get messed up when actually doing it. Much appreciated as always.

@@DonnieKluck You got this Donnie! Let me know how it goes. -Brett

@@AMain_Hobbies Brett I got it installed question I have is when I turn the when to left or right when I let it go it doesn't go am the way back to center. Not sure if it is just tires gripping the floor but just seemed odd why it wouldn't bounce back to straight (it is just off by a bit but you can definitely tell not straight)

@@DonnieKluck Hmm, most likely the servo saver in the steering system of the maxx. It's the two plastic pieces on the left steering post. Unfortunately, they're not adjustable, so after a year of use or so they should be replaced to get back some steering precision. After use, the two pieces slide on each other with dust and grit, and they sand each other down, making slop. This is my guess, there is no other reason it. Checkout those pieces. I think we talked about it in the Maxx upgrade video. Yeah: go to 6:00 in the video: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-l-zNaLi59aY.html -Brett

Just remove the old servo, and install the new. It's a direct swap. Remove the brace above the servo and you should have direct access. -Brett

Is this when you are trying to set the end points like in the video, or when steering normally? -Brett

It's best to have it at normal ride height on the ground. Good question. -Brett

Does it have an EPA adjustment knob? If not, you probably can't sadly. -Brett

@@AMain_Hobbies Ok thanks. I don't have that.

I have the same issue

@@nopeairsoft469 Are you burning through servos too? I've burned through 3 already. One stock and 2 of the upgraded servos.

Steering Dual Rate is similar to End Point Adjustment, except steering dual rate effects both left and right side equally when adjusted, and End Point Adjustment controls the left and right side independently. -Brett

@@AMain_Hobbies thank you soo much. I really appreciate your help 🙏

How old? Maybe this video will help: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-IShP13NAqgg.html&feature=emb_title -Brett

@@AMain_Hobbies Brett..... as always... PERFECT! Cheers mate, you ledge!

The number values are not really significant and you will always have one side with a higher value. It does not mean one side has more steering, it just means one side needs more servo throw. As long as you set your epa's correctly, the mechanical parts in the steering assembly will receive the correct amount of servo throw to achieve maximum steering angle (that amount of servo throw can vary side to side). It sounds like you have correctly set your epa's. Hopefully this makes sense. Have fun racing! -Brett

@@AMain_Hobbies Sadly I have no clue what I am Doing!!! Ive always had a Basic Futaba Radio. I just made both sides the same. Not sure what that did. These newer Radios have Way TO Much for anyone to get to know, Even a Disabled person.. Sorry..

@@johnm8558 John, I just got done telling you the values don't matter. All that matters, is your servo doesn't try to overthrow the limits of the mechanical steering system. Please, watch the video again. -Brett

@@AMain_Hobbies sorry Im just tying to figure out this 3pv! I have L and R set at 62 the right one goes to 62 so I just made them the same.. Thank you

Sounds like the servo saver parts, give them a check! They wear out over time and stop holding straight, so the car will wonder. -Brett

Anything with lots of torque will do the job, and then maybe waterproof if you need that. This WP250T is a good waterproof option: www.amainhobbies.com/ecopower-wp250t-waterproof-mega-torque-metal-gear-metal-case-servo-ecp-250t/p1466471 This savox is not waterproof, but a little more powerful: www.amainhobbies.com/savox-sb2290sg-black-edition-monster-torque-brushless-steel-gear-servo-sav-sb-2290sg/p536890 And this 1K TBL is the big daddy for power: www.amainhobbies.com/protek-rc-1ktbl-black-label-ultra-high-torque-brushless-waterproof-crawler-servo-ptk-1ktbl/p1331854 The first servo is probably more than enough for your truck and what I'd pick. Another component to think about is an upgraded servo saver. Stock servo savers are often set loose and spongy to protect the weak included servo, but with the downside they can absorb some of the steering instead of putting it down to the tires. So a good remedy, as long as you have a more powerful servo, is to use an aftermarket servo saver that you can adjust, and then tighten it up a little. In some cases, you notice an improvement in steering response immediately. -Brett

@@AMain_Hobbies thanks

If it doesn't have an EPA setting, does it have a dual-rate knob? It might be labeled "D/L" If you turn down the dual-rate, that will limit the steering travel for both tires together, where EPA does the left and right side independently, but at least it should help save your servo if its overextended. -Brett

Unfortunately you can't set the left and right independently, but you can back down the throw as a whole using the steering dual-rate knob. -Brett

It will be easy with that transmitter. In the Menu find EPA and then adjust. -Brett

@@AMain_Hobbies thanks, already did it~

One day my friend... one day. -Brett

@@AMain_Hobbies Made my day! But at now its only me and my mini e revo.

he specifically mentions that this transmitter does not have EP adjustment.

Unfortunately no you can't. -Brett
