@@speedrungermanyodwk thank you! Thank you! Since this video it has gone as fast as 108 mph on 4s, 102 on 3s and 99.6 this morning in 4s on the stock motor.🙂

@@oliver-eb6pf my thoughts, exactly! Brian absolutely does a phenomenal job on his test!

@@RCrepairAndBuilds thank you!

@@logandriggers1709 🤣

@@RCrepairAndBuilds Thanks man, I am thinking it will hit 65+ on the stock motor with your adjustable motor mount and a 18t pinion! Looking forward to checking out your video!

@@BriansRCStuff I hope so, I'm going to check it with the stock 16t then the 18t on the same day, same battery etc etc..

@@RCrepairAndBuilds awesome! I am going with a 4 mph difference but who knows!

@@RCrepairAndBuilds thank you. Happy 4th to you too! It figures. The first run did not register properly on the GPS. It was probably 100+ but I’ll try again soon.

MI’m me has really n flawlessly. Did a bunch of videos with it. I have a different motor in the car at the moment but this one will be going back in later.

Yeah man, of course! Looking forward to trying the motor mount! Hope you had fun in the mountains. I made it to the beach today.

You know, I think they might be but I did not compare part numbers. I am on vacation but could look at the manuals when I get home.

Thanks for checking it out!

This is the first I have heard of this. Why is this unique to 4WD cars? Are you saying there is too much slop because of the servo savor? Thanks

@@BriansRCStuff some more than others is whats been my expeirience

With the stock Traxxas transmitter you want about 1/2 mile total per run or about .25 mi. per each way or about 650 feet each way away from the transmitter you can see the distance of each of my speed runs on the GPS and you take that distance and divided by four calculate how far away from the transmitter on each run. If you’re only going 60 or 70 an hour, distance, but when you’re gone, you need every bit of that. It is tricky though, because unless you have a feel for it, you can easily go out range, which is of course not good. Also, fresh batteries will help maximize your range, and I did increase the height of my antenna, which helped as well.

Thanks! 100+ mph on 4s next!

Absolutely. This set up is only good for one or two runs and it needs to cool down but it’s fun! I am going to try for 100 miles an hour on 4S soon. It should do it.

🤣 That is brutal. My main problem with with my cars going off course.

Sorry, I am not sure. What kind of motor are you running now and what are the specs?

@BriansRCStuff the motor in the truck is like a cheapo that doesn't say. It's the only one that the esc beeps when I turn it on. I hooked up two different old hosim 2845 motors from the x08 and it didn't beep at all when I power it up. Only this cheapo motor.

@@eliflynn7282 hmm, I am really not sure. Maybe just try to run it and ease into it and see how it performs.

@BriansRCStuff it acts like a beefed up 2s really. With a 50c 3s it should boogie pretty good. At least 25mph.

That thing is sketchy as heck!

I did cut out a airflow slot in the back of the body, and I trimmed the body a bit so that the backend doesn’t act as much like a parachute… I appreciate you bringing that to my attention because I probably would not have considered it before. I was hoping as it ran okay at 50, with trimming the back of the body I hoped it would be good for 70+. I think I’m gonna give it at least one more attempt. 😎

Cat like reflexes over here… I cleared it.😂….. yeah, I got lucky. Thanks!

Thanks man! Mine has been dead on (some cars actually read slightly slower than you are going) but great point. There is a lag in the readings so if you crash while accelerating it will not have time to register the top speed.

I am SHOCKED HBX would say only use a USB charger and to store fully charged. LIPOs do not like to be left fully charged or discharged and should be stored around 3.8 to 3.85v per cell (about half charged). Your USB charger is fine for charging a 2s LIPO but getting down to storage voltage can be tricky without a hobby grade charger. What you could do for now is run it down to about 3.8v per cell or run it down a bit lower and then charge it back up to around 3.8v using a LIPO voltage checker to get it close to storage charge. Even if you get it to say 3.75 or 3.9v per cell, the LIPO will be way happier than fully charged. Leaving a LIPO fully charged will degrade the performance/capacity over time and if it was to catch fire, would have a lot more energy in it and would be a much bigger problem than one kept at storage voltage. If you want a good hobby grade charger at a great price, check out this dual channel unit (I have tested it). For under $80 on sale it is a great deal. Another great option at a low price is this more basic one channel charger for around $40 (I have also tested this one). a.co/d/0286S1e9 HBX is wrong is that is what they said.

I think most of the HBX manuals state something like "Do not leave the battery pack uncharged or fully charged for long periods of time." This is a dumbed down version of keeping it at storage voltage.

@@BriansRCStuff what Haiboxing told me is Exactly what I told you ! And they told me to fully charge the batteries every 7 days or so ! As I said I'm new to this and on a fixed income a small Is social security every month . I've looked on amazon and they have a ton of balance chargers and it's very Confusing I saw some on there in the $23 - $39 range but I don't know if the will both charge and or discharge a battery to a storage charge ! Haiboxing sent me 4 batteries for the car and going by what they said I fully charged them to store them and now I don't know how to discharge them the the right voltage to store them and if I just run them in the truck I have know way to know what the voltage is on them !! Any Suggestions ??

@@timmy4539 Well... that is how you charge a NiMH battery but not a LIPO or LiIon. Sadly that person was misinformed. : ( I am happy to try to help you to pick a good budget charger if you send me a link(s). If you want to email me in email address is in the about section of my channel or we can try to do it here (sometimes KZfaq deletes internet addresses from comments when you try to post them). The chargers I sent you links to will charge/discharge/storage voltage charge but there are many other good options out there. You are not going to ruin a LIPO overnight but leaving them fully charged but over a period of months the performance will degrade. I am really anal about keeping mine at storage voltage as I want them to perform at their best and I test LIPOs for many manufactures. When I do speedruns, I don't to wonder if I am getting the full performance out of a LIPO.... so within a few hours of running a LIPO, I put them to storage voltage. You would run your truck about half of its run time (say like 5 or 10 minutes) to at least get the LIPOs closer to storage voltage. You can get voltage checkers like these www.amazon.com/SIPYTOPF-Battery-Voltage-Warning-Indicator/dp/B0B8XDLVMS/ref=sr_1_9?crid=1IVFSA9S6IPGX&dib=eyJ2IjoiMSJ9.QcWJqPcdQnL9CI2wFHHdMpPGDunLsxCyelvBgssx4J9XTKeLmydca4r6uVSChzNQBjp-Fmnkw4VTyTxuEpewRDrea1S-6nyqeYC3wrrVz27KB0h4gyZMN1Hgu_Udr4948l3OKyut_p7Ybfe-06akQpGvBu4vDSBh5CmTY_q1NLYabsy0ItXwW8I1CWPlK-rurC3wYcdxIfACxvUiuoMQR0Vbp4vx5r-L_N1FLL7L__I.ixXQXQ21JazuFknoGXdT16yk9FsnrrpFYrg-gz8jQKo&dib_tag=se&keywords=lipo+voltage+checker&qid=1719200213&s=toys-and-games&sprefix=lipo+voltager+checker%2Ctoys-and-games%2C73&sr=1-9 They are cheap and are really nice to have when running a RC car or truck. Or, when you get a higher end charger, you are good to go.

@@timmy4539 I have a different brand but one very similar to this one. This could be a good cheap option (assuming it is build as well as the Turnigy Accucell 6 that I use). a.co/d/07rTGVKy

It is a ripper!🙂. Thank you!

I don’t either. I tested their Rapid blue packs and they were solid! I hit 99 mph with the Turnigy and my top of the line SMC hit 102 (all 3s). I was impressed! This is my fist Panther and it impressed me! I wish my GPS didn’t good on that 1st run with it! RC explained seems like a great tester but I would still like to see him do some actual speed runs and not base everything on bench racing. Would be really nice data to share with folks…. But he says the roads around him are very good so I get it. He does have some nice equipment that I wish I had.

Thanks!

Thanks for checking it out!

Thank you! I just broke mine the other day, but I don’t think my kit came with an extra… I think I would’ve remembered that. I’m second-guessing myself now and I guess I should probably take a look. Yours came with the whole constant velocity shaft basically an axle and a dog bone? In the manual, there’s a breakdown of all the parts. You can get most of them on Amazon or eBay and in most of my video descriptions I have a link to where you can get them directly from HBX. I have broken, a rear, suspension arm, cracked the body, shattered my gears when a motor seized off at 65 miles an hour, a rear hub knuckle, and I could be forgetting something 🤣

Thank you, I appreciate the kind words!

Yes, virtually any vehicle with 12mm hex. They don’t work on my vintage Kyosho due to how the wheels mount.

Don’t forget the thread locker, however!

it DOES NOTget that hot..sry

@@whitmanft sounds like a great setup! What fan are you running?

@@BriansRCStuff RC Motor Fan Radiator Aluminum Heat Sink Twin Cooling Fans Thermal Sensor for 1/10 RC Car 540/550 off Amazon..i tried to pst the link from Amazon but it wont paste..?

@@whitmanft thanks!

🤣🤣🤣🤣🤣

The mount only allows for two options… There’s no slider or anything to adjust. 🙂‍↕️

@@BriansRCStuff any way to use the different pinion sizes?

The 17 T seemed to line up good...?

@@whitmanft I believe if you flip the motor mount you can also run a 14t in addition to the stock 16t. Some people have said you can drill a slider hole in the motor mount and fit a few different options but that sounds pretty ghetto… I have not tried that.

@@whitmanft is that a question or a statement?😂 I have never tried, but I would be cautious because if it fits well for the 16 T, it should not also fit well for the 17. The mesh might be a little tight, but I can’t say for sure what you’re seeing. 😎

Thanks for checking it out.

I am pretty sure the 16890A only goes about 35 mph on 3s (I recall my 16890A going just under 35 on a 850 mAh 3s with the stock setup and the SA isn't really after). I have been tempted to put a bigger 3s in here and see how much quicker it is but the way I have it set up there isn't much room inside to do that. Here is my buddy RekRC and he hit 36 with his SA (the ESC is probably a little less restrictive as it is made for 3s (and he ran a 2,200 mAh LIPO) while mine really isn't happy running 3s. kzfaq.info/get/bejne/Y5aDn9OQnJq9j6s.htmlsi=FObHoMqXV1aGgVmp&t=111

Thank you!

THank you! I would love a Randiolink setup too! Maybe one day but it is hard to justify when the Dumbo offers some pretty good range! I prewarm my LIPOs before I do speedruns (almost always). Today it wasn't much of a concern but I try to be quick about getting my runs underway so that they do not have time to cool. I feel it gives me the best performance possible and more consistent results. But yeah, your logic makes a lot of sense to me!

@@BriansRCStuff Right, right.. I forgot you had the heater pack 👍 glad you're enjoying that motor and ESC combo! Runs hot, but not bad performance for the money

Are you saying they are too strong? Remember how I problem with it and it was stock but when I modified it, they were definitely too strong because I was running a more powerful ESC but then I just adjusted it. I have not personally tried it, but… I hear a surpass hobby program and card works on the ESC. I would confirm for you, but my truck is broken and has a different set up right now..

Here you go kzfaq.infoYd-xGvnVmDs?si=qAzkwA7qgFcNlHmP

@@BriansRCStuff They are very weak. when I press the brake/reverse in forward motion the vehicle beeps and just keeps moving forward like nothing was applied.

@@maxforce that doesn’t sound normal. Mine didn’t do that.

@@BriansRCStuff ive seen another youtuber complain about it.

No heating issues going 1 or 2 speedruns at a time. Clowning around with speedrun gears quickly = overheating issues.
