Set steering servo endpoints Arrma Fireteam 6S with SLT3 transmitter - amp draw measured as well.

Setting the endpoints on the ARRMA Firetam 6S. It's recommended to always set your endpoints on any RC prior to your first run. Most manufacturers include this information in the instruction manual included with a new RC, but I didn't find this info anywhere in the instructions for this particular RC, so I've taken the liberty of making this video. I know it's a bit long, but people wanted more specifics, so here it is. On the amp meter, I was reading about a 1.5 amp draw, which I think is the stall current for the S652 servo at 7.4V. So if your endpoints aren't set, you can burn out the servo.

Perfect, dude! I just got my Mojave 6S V2 and I wanted to make sure everything was 100% before I drove it. I checked all screws and stuff, then when I dry tested it for power and throttle and everything I noticed my servo was trying to pull the steering wayyy too hard and remembered to program, but wasn't sure how. This video was absolutely perfect! Everyone needs to do this to their new rigs before their first run to ensure their servo doesn't die so soon!

[@dgitalchaos]

Glad the video helped. I know it’s a bit long, but I thought it was important to include the amp draw so people can see why servos burn out if you don’t set the end points.

Thankyou for the straight forward and Informative video!

I had one that was shorter and direct to the point, but people kept asking as to why things were a certain way.

Perfect thanks for this really appreciate it !

Glad I could be of assistance.

[@reconrc1787]

Great video sir! Can you tell us more about the amp meter and where you purchased it?

[@dgitalchaos]

I got the amp meter from eBay. I wish is saved maximum values, so I could test amperage on runs, but it doesn’t. It’s just a cheap amp meter with various other readings. www.ebay.com/itm/284920547921?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=NunrwCbTTXa&sssrc=4429486&ssuid=BL9jz6a9Qo-&var=&widget_ver=artemis&media=COPY

[@reconrc1787]

@dgitalchaos Thanks for that. Yeah I could see how it saving max values could be useful. I typically end up upgrading to the Castle MM8S esc to get the log data options.

[@dgitalchaos]

@@reconrc1787 I have a M series Mac, so I don’t have Windows, otherwise that would be an excellent option.

[@lukerecore3211]

Will that work for a ARRMA granite v3??

[@dgitalchaos]

I imagine it should, I believe it uses the same transmitter.

[@lukerecore3211]

@@dgitalchaos Thank u for the knowledge. I just blew my stock servo and I think that it was over working. And yes they r the same transmitter the slt3.

i have fireteam, but what is endpoint? i do not know what this is for?

[@dgitalchaos]

So a lot of people are burning their steering servo because the servo tries to travels further to the right or left than the RC is capable of turning. By setting the endpoints, you’re telling the transmitter where those physical limits are on the RC so that the servo does not try to exceed those limits. The affect of this is proven in my video based on amp draw - which equates to heat and burning servos. The amp draw in the video is conservative as these servos can pull up to 5 amps. You can ignore the amp meter altogether, as that is information proving the effects.

[@johnyortiz8774]

I used your tutorial to set my endpoints. Thank you for this because the manual doesn't even mention the radio having that capability, much less explaining how to do it. I have an issue though where I set my center point for the trim and then it seems like it changes when i go to run it. I don't know if there is just a bunch of play in the system or what. I turn the unit on and set the steering trim to center before connecting my servo horn and everything will look centered. Next time I look it's off and by a decent amount. Very frustrating.

[@dgitalchaos]

That certainly sounds strange. Have your tried centering everything and rebinding the receiver? Or the servo potentiometer might be going bad.

[@johnyortiz8774]

@@dgitalchaos It actually was the case with the original servo and the upgrade I put in. I noticed last night my servo saver seems to engage really easy one way and you have to put a ton of effort to engage the other way. I think that might be at least part of my problem. Seems strange.

[@bryanspanjer3213]

Also, there is a lot of play on the left side especially. There is vertical play (considerable) of the bellcrank assy. I plan to disassemble it and place shims to prevent this. Just my two cents. Enjoy y’all!

[@johnyortiz8774]

@@bryanspanjer3213 I planned on not really upgrading until parts broke on me but I may go ahead and upgrade my steering assembly items to try and tighten that up.

What is that amp meter and where can we buy them pls my man That was an awesome bit of kit even more than the actual fireteam IN my eyes absolute Fabulous 😍😍🥳💯 And the detailed show is very welcome Thank you to whomever asked for this Couldn’t have asked for a better show ✅👌🏿🔥🔥🔥😊

Amp meter measure the amperage draw of a device. It’s usually not needed, but I included the info to show why the servos burn out. I got my meter from eBay, and soldered a connector. www.ebay.com/itm/284920547921?mkcid=16&mkevt=1&mkrid=711-127632-2357-0&ssspo=NunrwCbTTXa&sssrc=2349624&ssuid=BL9jz6a9Qo-&var=&widget_ver=artemis&media=COPY

[@luisfontanez1770]

Is this the same on 8s exb outcast?

[@dgitalchaos]

It’s different on the newest 8S Outcast, as that one has the DX3 and SR6200A receiver. I don’t have a video for the DX3.

[@mathiatube]

Tried this and the handbrake servo was activated when the A/B button was hit. I read elsewhere the handbrake servo needs to be unplugged for the steering endpoints to be set. I’m going to give that a try next.

[@dgitalchaos]

Strange, as you can see in the video, my handbrake didn’t activate. I’ll have to look into it more.

[@JerryJrsGarage]

My handbrake activates also and this doesn’t steer left only right or straight with my savox servo

[@dgitalchaos]

@@JerryJrsGarage I haven’t tried my Savox, but try disconnecting the third channel at the receiver for the hand brake.

[@JerryJrsGarage]

@@dgitalchaos Thanks! I had to remove the servo arm and adjust that then I got it! Then it was backwards right was left and left was right but I flipped the switch on controller and it actually worked like a charm! Curious what the difference is with a brushless servo I could have had for like $9 more lol 😂 I just am glad to have it functional again! Thank you for the fast reply!

[@dgitalchaos]

@@JerryJrsGarage the brushless servo should technically last longer, and produce less heat, but actual mileage may vary.
