I love that thee xmax just fit and cleared everything on the table 🙌
Nice upgrade. Odd, I didn't get notification of the video. Glad I came across it
Doug Christensen sometimes I wonder about how reliable TH-cams notifications are. I have had a few people tell me they were never notified that I posted a new video. Glad you came across it too. Thanks.
@@ReadytoRunRC It did pop up later. Just good karma that I'm drawn to your videos.
Video was done perfect and nice area looks peaceful
The Scanline Man thank you! It is just a peaceful small PA town in the middle of nowhere.
The gps on the gopro is amazing! I am going to get a hero 7, and I am so excited to use this!
Yes I love my GoPro even more since I found out about the GPS Speedometer feature. Have fun!
Great video, thanks!
Thank you for checking it out!
Very nice man. That’s a sweet car👍👍
damn right
Cool stuff bro
Tibor Von thanks! 👍🏻
Awesome dashboard.
jdpasl thank you. Just discovered how to do that a couple days ago.
idk if it's true in modern RC but a long time ago I read that electric motor rotation speed is limited by voltage and rotation torque is limited by amps. so that could explain why you were getting more torque but similar top end. as that particular 2s had similar voltage as your NiMH but more mAh. I'm curious if a brushless motor would exaggerate the gap between the two batteries.
Very awesome! Lipo definitely makes a big difference 2s seems to be equivalent to nickel but 3s is huge difference!
Delaware RC Man it made a difference. Not as much as I was hoping but it was noticeable. I am thinking now of pairing the 2s lipo with a different gear setup to get a higher top speed.
@@ReadytoRunRC when I added 2s lipo to my crawler it barely changed anything except maybe the low end control and punch compared to nimh but when I did 3s it's like it doubled in speed, very awesome now!
@@DelawareRCMan I love it
I have one of those xt60 to traxxas conectors and i just sanded it a bit to fit the modern trx id plug lol
supboy666 that would work too. I just wanted to show people who didn’t want to have to do any sanding or filing that there is a plug adapter that fits.
Ready To Run RC yeah that’s good too but the sanding is very little and the fit it really nice and tight so it never pops off when getting rough!!!
the plug that is on the latrax is specific for nimh batteries. other types fo traxxas connectors of for strictly lipo. i just converted everything to dx60
Carlo Chong I eventually would like to convert every to the same style plug.
You could add the 14T pinion and spur gear from the rally car, along with the 2s LiPo. You might get 25mph.
BUILTLIGHTWOUNDTIGHT gearing was going to be one of my next mods on this. Thanks for the suggestion!
Thats what im looking forward to with this hobby the ability to upgrade and tinker . lol
James R 😂 there’s plenty of tinkering with this hobby.
Song?
What camera do you have on the car and how did you mount it on the body?
I used double sided mounting tape to put my go pro on.
Venom 2s 2000 battery fits perfect
It does. I have one of those too. Bought it after I made this video though.
Ok so I got my two oldest kids into this hobby with a pre runner and a Teton. Bought a lipo2s for my sons Teton to keep up with the brand new pre runner. Motor immediately smelled. So what motor should I look into for these two units??
The stock motors on these are known to not last very long and the lipo’s definitely shorten the life even more. I replaced mine with a cheap brushless setup from goolrc. I made a video of it and it’s on my channel if you want to check it out. I haven’t ran it much after I made the video because I’m constantly getting knew stuff in to unbox and check out. I can’t tell you how long the motor lasts but running it on 2s really wakes the Prerunner up and makes it so fast.
I have this truck, have a stock nimh battery in it, what are ways I can make it faster without worrying about breaking it or overheating? Brushless? Is that hard to make it brushless and requires a lot of money? I want it to be a little faster, not a ton, and not sure what to do. Also, I just snapped a drive shaft in it, should I get aluminum drive shafts and the upgraded metal shocks, would that make a difference in ground clearance and performance? Thanks!
The 3S will make it run hotter. If you want some more overall speed without spending a lot of money, you can change the spur gear and pinion gear ratio. Putting a bigger toothed pinion gear and a smaller toothed spur gear will give you a higher top speed but it will slow your accelerating speed a little. Yes get the upgraded drive shaft. Upgraded shocks will help the performance and could change the ground clearance. I am getting upgraded shocks and will be putting them on soon and making a video about them.
Anything other than stock battery will make the motor run very hot!
Confirmed lol
The lipo the battery you used is longer available on Amazon... Could you provide another link to one that would also work?
Unfortunately they don't have any single batteries in this size listed anymore but here is a link to buy a 2 pack of the same battery amzn.to/2ZLsamN and if you need plug adapters for these batteries to fit your traxxas/latrax, here is a link for theDeans T Plug Adapter to Traxxas amzn.to/2Fe0jm3
Does your spur and pinion get dirt inside the case?
thank you
I didn't notice it to be really dirty when I last looked.
Any updates on this setup, with the LiPo battery upgrade, and any other electrical components being switched out due to overheated and worn out motor, ESC, servo's, etc.? Thanks for any and all input. Stay safe!
It’s all switched out. Stock motor is junk to begin with so I threw an Amazon budget brushless setup in and it’s actually been running good on that. Still running stock servo. Haven’t had any issues with that.
The link from xt60 to trx is not working?
Any way you could send me different link?
amzn.to/3P2xNry here you go.
+1👍 swift!
Shouldn't be an issue keeping nimh and swapping back and forth on latrax from one to the other, correct? I Just need adapter, 2s batt and lipo charger to do so?
Just like so I have more batteries to run with haha
Tim Nenciarini nope there’s no problem at all. You just have to remember when you switch from Lipo to NiMh to turn the low voltage detection on and off on the esc. And yeah that’s all you need.
Thinking about getting one for a carpet track and racing it, what do you think?
Heck yeah! Go for it!
I’m running 2s lipos on my sons prerunner and Teton, It’s quicker and probably gained 1-2mph, I will say the stock motor does get really hot. Have fun bro.
Upgrade shocks and arms guys. Thanks Amazon. Lol
Is there any way I can fit a traxxas 2200 mah lipo in it
Probably with some modification. I stand my lipos on their side and cut a hole in the chassis for a battery strap.
Wish someone would make a video comparing the battery types toward the middle & end of their respective discharge curves. I know both battery types drop off voltage over the runtime - with the NIMH dropping off more at the start. Maybe I’ll make the video... lol. Just interested to see the changes in top speed from start to before the major voltage drop / cutoff.
There you go. That’s an idea. I never thought to do that.
Hows it holding up.. Alot of reviews say dont put lipo
My stock brushed motor died. Not sure if it’s from the Lipo or just because, from what I have heard, the stock brushed motors are junk. I’m sure the Lipo helped kill it sooner. I’m going brushless soon.
My question is; what are the best shocks for this rc car that you would recommend.
I can’t answer that because I did make a video of putting RCAWD aluminum shocks but they weren’t the best option. I’ll have to try other brands to see which is the best option.
@@ReadytoRunRC Thanks for the feedback, one more question is if you know what the best camera is for an rc car?
@@hollisterwithtomo504 are you talking fpv or just a good camera to mount for different angles? I am not really into fpv so I can’t answer that but a good camera I see a lot of rc TH-camrs use is the Insta 360.
Would a 5700mAh 7.4V 25C 42Wh 2s lipo be too much for this truck and overcharge the esc or break any other parts?
I don't think so because the mah and wh are just the amount of energy stored in the battery and how long it can supply the energy. You're still only supplying 7.4v's to the esc and motor.
Ready To Run RC thanks man
@@tristonjames6197 make sure to get the dimensions of the battery so you know it will fit before you order
the face in da wall it was a battery I had on hand it is rather large for the truck tho takes up the whole space and gotta Velcro it in each time but plenty of run time
And its heavier I tried 2s 5800mah traxxas . Run time you need alarm clock becuase otherwise you'll over cook your lasagna for having fun to long hahaha
How much run time do u get from fully charged
About 20 minutes.
I bought that 2pack of Ovanic lipos, and they don't come even close to fitting into the car. Theyre way too long. Mine measures at 4.2", which is what the listing says. Are yours shorter?
Yeah mine only measure 3.5”
@@ReadytoRunRC Gotcha, thanks. I see the Ovanic Air are longer than the Ovanic car. I'll have to order the other ones. Thank you.
Consider removing the listing to the 2 pack of Ovanic airs since those don't work. Maybe that'll save someone else from making the same mistake.
@@timkorn2102 I will have to do that. I didn’t realize the battery lengths were different. I apologize for putting the wrong link in and thank you for bringing that to my attention.
@@ReadytoRunRC So, is the correct LiPo link been updated for the correct size? Thanks.
@@flhandster4395 yes I switched the link to the right one.
jesus why is the xmaxx so HUGE 😂
does it have good torque if i want to make a dirft acr with it
??
It does.
@@ReadytoRunRC is it worth getting brushless?
@@hpickle2896 yeah. You’ll burn the stock brushed motor out pretty quick running lipo. I burned mine out after about 3 battery cycles. I put a cheap goolrc brushless in it and it’s ridiculous just on 2s. Almost too fast to control.
Would these adapter work for xmaxxs too ?
Yes they will work.
I wouldn't run an adapter on such a high voltage vehicle. It's fine on a small 1/18 but adapters can't handle much current and will catch fire or burn up. You should saughter on a new connector or get a shop to do it
Is 3 cell battery to powerful for this, and do you have to sauter on a traxxas connector?
The stock esc won't work w/ 3s, and if you choose to get an esc that can, you are very likely to strip your diffs and snap your driveshafts, and your unlikely to get it above half throttle anyway
cringyman172 thanks for the info. Good to know.
@@cringyman1729 Would it work if you got aluminum driveshafts and GPM ball differentials or can the truck not handle it even with upgraded parts?
@@bccbreaks6712 chances are that you'll do a monster wheelie and flip it before you get past half throttle.(on 3s) I think the aluminum diffs might still strip, I saw someone on Reddit who did the exact thing.
@@cringyman1729 Ok, so I am better off just leaving it with the brushed motor and not messing with any upgraded battery or motor power stuff?
Will venom 2s 10000mah works for latrax rally? I'm trying to set world longest burn out indoor. 😂😂
😂 2S is 2S no matter what size Mah you are using.
RIP tires and probably pinion or some gear
Did the battery ever burn your motor .
For whatever reasons it seems to have blown 2 motors of mine already .
The first time i used the battery after setting it up and activating the low voltage detection as you did , the car ran for few spin then stopped . Then as i was trying to figure whats goin on i smelled some burnt odor around the motor but no smoke .
Then i assume the motor was broken because it wasnt a new one . and bought another one , same scenario happened , it ran for a few and stopped working again and same smell . I do not want to replace another motor without figuring out what the ISSUE might be .
I was hoping anyone could help me out here.
Thank you in advance
These brushed motors aren’t very good. Mine burned out after 4-5 more battery cycles. I’ve seen a lot of people with the same issue. They just can’t handle the lipos. I switched to a brushless setup.
@@ReadytoRunRC I see .
What specs or brand of brushless setup would you suggest for the prerunner truck
@@Meckanimal I am not suggesting this but I went with just a cheap setup from GoolRC on Amazon. There’s a video of my brushless conversion on my channel. I’m happy with it. I only run 2S with it but I can get close to 30mph on it running a different pinion and spur gear than what comes stock.
@@ReadytoRunRC I'm using the same customed pinion and spur gears you have. I did the mods few months ago after watching your video . I'll take a look at the brand you mentioned then compare others and see the best bang for buck. THANKS
@@ReadytoRunRC Greetings friend ; I upgraded to the GooIRC brushless Motor and esc anew . But I do notice a latency in response on the gas .sometimes I lose control /connection with the car especially after hitting top speed acceleration when its time to steer .
Did you experience so similar issues
No soldering iron?
Can solder if you want to. Some people don’t know how to or like to so I’m showing the adapters that are available if people don’t want to solder.
if you buy the prerunner from the traxxas website then will it come with battery?
If it says Ready To Run on the website then it will come with a stock NiMh battery.
Ready To Run RC so it comes with a battery?
It should if you buy the Ready To Run one.
Ready To Run RC so do you need to buy the 1200MAH 7.2V FLAT battery before buying the prerunner or it already comes with battery?
SuperSmashBros.mp4 it tells your right on the traxxas website what battery is included with the truck.
if i get a 4s for the latraxx sst would my engine break?
No doubt about that.
@@ReadytoRunRC so is Safe?
@@m1steryguy390 no definitely not safe. You will definitely burn up a motor or esc with that much. You asked if it would break your engine. I said there’s no doubt it will. The esc or motor is not made for that kind of power.
@@ReadytoRunRC Alright a 3s would be The max?
@@m1steryguy390 on stock esc and motor I don’t think it could handle that much power for long before something going wrong.
I tried to get a battery pack from given link but its sold out. Do you have any other link where i can find it?
I'm not sure why it says it's sold out because I just clicked the link and it says there is 15 in stock. I do not have another link for you.
Can you do training mode with a lipo battery?
Not sure about that one. I don't know if the low voltage cutoff would be active for a lipo in training mode. I would just run the NiMh battery since it's a lesser powered battery and you're just going to go slower in training mode to begin with.
@@ReadytoRunRC slower is good. Lol. My kids are small. They go through he stock battery quick.
@@Big_Fe11a l wish I could check on that for you but I swapped out the brushed esc and motor and went brushless with it.
Yes, you can. It's slightly peppier than the training mode with nimh, though.
can you use a traxxas 2S?
You can use any 2s. Doesn’t matter what brand.
1mph. But torque at take off much better with lipos.
I have the same rc traxxas Latrax Prerunner truck
Awesome
you can just take off the shell of the connector to the esc to for the battery. Apparently not enough research.
Apparently
@@ReadytoRunRC sorry if that came across a but rude. I was in a bad mood yesterday and was leaving bad comments on people's videos. Sorry mate.
@@JG-oc9gc no problem. I don’t let bad comments get to me. It’s TH-cam. Hope you’re having a better day and in a much better mood.
@@ReadytoRunRC thank you I am. Enjoy your day.
That battery rubs the driveshaft...... Wish i would have known. Im gonna just velcro it vertically.... (bottom of battery, the side of the radio encasing, and a little strip on the chassis along the edge under rhe battery clip nub.)
Yeah I noticed that too after running it for a little after I made this video but thats a great idea using the velcro.
@@ReadytoRunRC a main hobbies has pure tech quick mount straps. Ordered some yesterday. The straps are mounted to a piece you just stick on I guess with a very strong adhesive. Saw a guy with a Teton had em. Just put a new savox micro servo in my prerunner. Adding 1/10 rally wheels from k force (which may be same height as stock tires not sure), 2430 motor and esc, hot racing axles, and the traxxas gtr shocks next. Motor and wheels/tires will be here last since they are coming from China 😭
I been looking at the Savox servo too. I'll have to check out that battery mount you are talking about. I'm looking to get the hot racing shocks and also the axles too. Sounds like you are putting together and awesome build.
Are they really that fun bro? I want to get one but I’m scared I’ll get bored of it in 5 seconds it’s $120 so that would be really bad
They’re fun when you upgrade them. Good beginner RC but yeah you’ll want to go faster eventually.
@@ReadytoRunRC they're good for beginners getting them to learn how to fix them since everything breaks really easy. I mean really easy.
Should try a 9.6 nihm, probably easier on the motor
probably but it's the stock LaTrax motor so it will burn out eventually either way. They are not that good and I was planning on going brushless, which I did.
What motor and ESC did you use?
My stock motor went out driving fast on lipo and I upgraded to brushless and switched to castle creations sidewinder micro 2 5300kv motor and had switched many things to it.
need more space luv it tho
Yeah especially after I did the gear change. Need a lot more room to run with it.
how fast does the prerunner go?
You must have missed the part with the speedometer on the screen but I topped out at 18mph.
@@ReadytoRunRC but it goes fast right?
@@ReadytoRunRC and no i didn’t miss the part with the speedometer on the screen, sorry i just got carried away
@@frost7724 Stock out of the box it’s not crazy fast. It’s a decent speed for a beginner but not that fast for anyone else. I wanted it to go faster so I did the 14T 54T pinion and spur gear upgrade. Goes a lot faster. Also will be upgrading to brushless.
@@ReadytoRunRC oh ok so if i buy the prerunner and drive it then it goes really fast?
Just bought these batteries and they changed the size format. They are now too long to fit into a Latrax chassis. Super disappointed.
Did you get a 2200 mah battery or was it a higher mah because if it’s a higher mah it will be bigger.
@@ReadytoRunRC yeah, it was the 2200. Unfortunately it just barley overshoots by a couple of mm. I even returned and reordered them to see if it was a batch-fluke, and the most recent ones were even longer, so it may very well be a crap-shoot. My guess is that this brand gets cells as they can from the cell manufacturer (no fault of thiers). I ended up going with shorter / taller brand, and having it sit on its side. Raises the CG a little, but otherwise is fine, although I had to right a Velcro strap and foam wedge to keep it in place.
Thanks for the follow up!
@@snotrockits ok. The other thing I was thinking was Ovonic has one for air and one for car. The one for air is a little longer than the ones for car. But maybe they did change the dimensions which isn’t good for people looking for the same size I have. I did the Velcro strap too. I cut a slot in the chassis to run the strap through.
Wow! It went from 16mph to 17mph! °0°
I know! Mind blowing isn’t it?! The top speed isn’t going to change much at all just because I put a lipo in it. It changes how fast the truck accelerates to get to that top speed. Thanks for watching!
Just solder a male xt60 in the car
The adapter is to show people another option who may not be able to solder or don't have the tools needed to solder.
Iconic is very weak. Not the best choice for a speed test. Should’ve went with Traxxas, or even Lectron.
Still proves 2S is faster than NiMh. That’s the point of this video. Not which 2S lipo is the best.
LOL
