- Hey guys, Go fast here!! Today I am going to be telling you guys about the differences between a Tmaxx 2.5 and 3.3. For some of you experienced guys this should be common knowledge for you, but for the new people looking for a Tmaxx or people who just want to know, this is for you!!
First!!
Really appreciate it dude!!
I ordered a .15 tmaxx a week before they came out with the 2.5. Luckily i was able to return it and got an original 2.5. Last week my 8 yr old and i got a 3.3 revo and a 1/16 slash for $50 at a garage sale!! Im moving the 3.3 from the revo to thr tmaxx and using the power up program to exchange an old pro .15 motor for a new 3.3!!! Going to have some bashing the tmax and revo with my son this weekend!!
I have a tmaxx from 20 years ago. Today's Tmaxx Classic is essentially the same truck. I didn't realize that until you were explaining the engine differences. Thanks for sharing.
I still got mine from 20 years ago also. It's been sitting in my basement with a blown engine for 16 years. A bug bit me and I'm now swapping it over the a brushless system. Actually can't wait to take it out and have some fun with it again.
@@stoneyswolf What are you doing for the motor mount, hitting up ebay, 3d printing, other?
I find a 3d printed one on eBay I'm gonna try out. If it doesn't work I try something else.
About 10 years ago I had the 2.5 my dad had the 3.3. I miss my old 2.5. It was a wheelie monster. Took a break from RC’s for several years and recently got back into it. I have a 3.3 now I still love them. Along with an xmaxx a mini maxx (maxx) and a couple other lower end Traxxas eclectic. If you ever get a chance to play with the Traxxas maxx I highly recommend it. Thing is really fast and I bash mine pretty hard. After 4 months of bashing haven’t really broke anything. I wore out the servo saver in the steering system. Did burn up a esc on accident. The only other thing that actually broke was the wheelie bar. A lot of fun. I jump and crash this thing hard lol. Spray your plastics with WD-40 and let them soak for about and hour. (Be careful not to spray electronics) it softens up the plastic and makes them more durable. I thought it was crap til I tried it. But it works well.
Thanks for the WD40 truck!! I will have to try that when I get stupid with my xmaxx. 😂😂 I have looked into getting a maxx but I actually bought another truck.... you might know what it is. And I also have like 3 lower end electric traxxas cars they are a lot of fun to just go in the back yard and goof off with them. But it is a lot of fun to go out in a field and bash around with my dad. Glad to hear your enjoying the hobby again! I also took a year long break from rc about 2 years ago and I am glad to be back in the hobby. Thanks for the support!
@@GoFastRC hey I really though it was BS til I tried it. Try it on an old broken a arm. Try to bend it before. Then spray it and let sit for about and hour then try to bend it after. Big difference. Right now in Texas it’s 16 degrees and shocking there’s snow on the ground.. not normal for Texas at all.. anyways on cold days like this I’m more likely to break stuff. WD-40 😎 makes it not really matter. And it’s safe for your plastics. NOT THE ELECTRONICS THOUGH.... so be careful around that stuff... I’m pretty sure that’s how I burned up my esc.... But there’s videos on UA-cam with people using it so their RC’s are more resilient on hard crashes. Check it out if you are unsure. But I think it’s saved me a lot of money
Thanks B'y, good information, I had a 3.3 awhile ago but had to sell it but my wife jus got me the 2.5, excited to get back into it, gotta order fuel tho she didn't get that for me, thought it took normal gas but that's ok this way I make sure I get the right stuff, thanks again B'y
In any case. Always replace the bearings and carbs first thing in either of these. You will be so happy you did.
My Tmaxx Classic with the 2.5R and O.S 11k carburetor and OS Lc3 plus does wheelies easy. Been running my Classic more and i like it better then the 3.3 but will see when i get the OS Max .21TM that i bought. In the Tmaxx 3.3
Great vid mate actually really help me find the difference between the 2, there's not many vids on YT with a full comparison like yours good work
Thanks man!! That’s really nice to hear.
Your welcome buddy keep up the great work
I got a 2.5 for very cheap. Barely run. I disassembled it clean the bearings. Castor oil to all the moving parts. Now it is ready.
2.5 floods all the time, carburetor has a manufacturing screwball design....I changed over to the 3.3, no more flooding problems ...I've set carb in every possible setting but floods every times it flips over and goes dead......restart have to rechoke engine on a start up and pipe fills up with fuel no.matter what ya do to it....other ppl have the same problem with the 2.5
Weird, I don’t have that problem with mine. But I have heard of people having trouble with the 2.5 and 3.3s
Same problem here my 2.5 has hated to idle I changed the carb to another original it got better and idles sometimes but you can definitely tell it can't regulate fuel enough I tried my buddy's 3.4 Losi carb and it was alot better on the bottom so I guess I'll by another carb soon but I still think Traxxas should have done something long time ago about it with the electric competition and all
The way you move your hands around reminds me of Scottt Kilmer
Idk if that’s a good thing or bad thing 😂😂
Both of course. We love the Tmaxx.
I wish Traxxas would do something for the Tmaxx owners and give us a wide maxx kit for them.
I have a traxxas classic that came with a 2.5 and swapped it with a 3.3 engine it’s crazy quick with it being on the smaller platform and the drivetrain holds up surprisingly well to my abuse I got the truck when I was 7 and I’m 21 now and got it out and drive it earlier today
Did you have to do any modifications when switching the 2.5 to a 3.3?
@@whackowheenie7839 no pretty much just bolted up you may want to put a different gear ratio in because the front wheels don’t stay on the ground because of the torque
There is no replacement for displacement! Nice video.
Just purchased online my TMaxx 3.3 yesterday can’t wait till it gets here. I have the the Rustler 4x4 vxl and CC-01 there cool and all but there not the same.
Lol I get that!! Your gonna love the trucks!!
@@GoFastRC i have Tmaxx .15 which I forgot to include
@@nighthawkj30A4 kickass!! I want one of those original tmaxxs with the Trx pro 15
@@GoFastRC yeah there where great when first released and still to this day. I had since 2002.
Reverse has held up good use it alot but ive been wanting a Tmaxx 3.3 since 2013 at least. so i finally decided to get one.
Yes your right on i have both trucks love them both and your video keep up the good work 👏
I have both battery powered and nitro RC's and by far my favorite are the nitros!
Hey bro! You’re channel has grown so much so fast man!
Yeah it pretty crazy that a few months ago I was at 50 subs and now I am a little over 200!! Appreciate the support!!
@@GoFastRC I was ur 19th sub... awesome!
Drivetrain overall is completely different. 2.5 uses smaller driveshafts and nonsealed 2 gear differentials. 3.3 uses the larger driveshafts and a sealed 4 gear differential you can put differential oil in. The sealed differentials make the 3.3 a much more tuneable and capable truck. Not to mention the 2.5 uses self-tapping phillips hardware and the 3.3 uses hex hardware. Steerings blocks are much beefier and better designed on the 3.3 whereas the 2.5 steering blocks always snapped where the tow links would screw into
I think I will be adding the 3.3 diffs to my 2.5
Any luck with that? @@zackjay71
@@zackjay71?
FYI.... The T-MAXX 4909 is an oddball model since it has the short chassis but came with a 3.3 motor and transmission with reverse.
Noted 👍
Great video. Really appreciate the explanation of the differences.
Sooo Cool - Nitro -4- Ever Battery’s are for Flashlights
i mean you sure because you need a battery to start the tmaxx
Honestly both are amazing in different ways
Always great informative videos
Thank dude!! Appreciate the support!!
i have the 2.5r t-maxx the 3.3 t-maxx then a 3.3 t-maxx with a rb 525 engine on it. an i always go to the 2.5r just cus its better on the nitro the space we have to use them local you dont need to go any faster. only thing id tell anyone to upgrade is to run a metal spur gear never managed to brake anything else on a maxx. big jumps flips crashed into kerbs metal rails the lot an only ever killed the plastic spur gears
Not everything is mentioned here. Tie rods are also completely different on the 3.3 they are thicker than the 2.5 and have wider tie rod ends this is to compensate the wider wheel offset of the 3.3 and turn radius
I have both and I love them both and I’m not sure why! Lol
I liked reverse I get stuck a lot. Also I'd floor it while I'm reverse then spin around and shift to forward and tear shit up.
Nice video
I’ve heard the 2.5 & 2.5R are a lot more reliable then the 3.3? Anyway great video 👍
I can’t really say if one is better than the other, as long as you take care of the engine and run it properly it should last a while. Thanks for the comment!!
In all honesty....the only difference between the 2.5 and the 2.5r is the cooling head....otherwise it's the same engine. Woop de do.
From owning my 2.5R in my classic i say its better then the 3.3
Hi Nephew. We enjoy your vids. Carm wants to drive cars with you.
Tell Carmen when COVID is gone we can drive in the back yard 😄😄
@@GoFastRC Carmen is still waiting to drive ur rc cars.. covid is still here maybe we should wait another year till it's safe to leave my house. Because I'm still to scared to go anywhere.. how about u
@@rcx8971 im not super worried cause i am fully vaccinated but sometime we should!
@@GoFastRC me to I'm boosted I'm on my 5 booster
Yikes@@rcx8971
I picked up a tmaxx for pretty cheap pretty sure it started life as a 2.5 after watching this video because it's been upgraded to a 3.3 but it has the black 2.5 transmission. Do u know what all u gotta replace with with the drive shafts to upgrade it to a pro built transmission
I want to upgrade my drive shafts and axles to steel shafts for my 2.5. I keep snapping the plastic ones. I can only find one for the 3.3. That should be different as well due to the length and width of the two models. Do you have any idea on what shafts I would need?
I honestly do not know. You might need to look on eBay or something like that. I know traxxas makes some for the 3.3 and revo, but idk if they will fit on the 2.5.
@@GoFastRC ya that is what I am finding. Nothing for the 2.5 model number 4910. Thanks
Swap over to the 3.3 control arms and have a wider stance or just cut the axles down to fit.
Is there anything I can do with the 2.5 plastic pipe to increase the horse power without upgrading to the 2 chamber pipe?
Not really. Non that i know of anyways. Easiest way to up hp is to help it breath better. Air filter and exhaust. Ths and traxxas makes good pipes. I have never tried traxxas but i hear they are wayyyyy better.
keep it up kid!
The 2.5r is the same exact engine as the the 2.5 the 2.5r just has the blue anodized head which is just for looks, when Traxxas tells you to upgrade from a 2.5 to a 2.5r they are LYING to you the 80 dollar higher price tag is just for the head
Great video!
Nice review.
3.3 not having reverse sounds like a pain in the ass compared to my new Traxxas Maxx electric.
Can you upgrade the transmission servo?
Yeah, the servos in the maxx series of trucks are standard sized servos so it’s super easy.
So good!!
Thanks dude!! Appreciate the support!!
These trucks really don’t have much in common besides name. The 3.3 only share a few things with the 2.5. Drivetrain is definitely beefed up on the 3.3. For $50 more, the 3.3 is the better value unless you really plan on upgrading the 2.5.
Hey man I finally got my classic tmaxx going, I was wondering if you use a fail safe or how you prevent runaways. It has never happened to me but I heard it does. How can you tell if your batteries are low
For me all I use the the fail safe that is programmed in my radio. And I can’t really tell if my battery is charged so I charge it usually every other outing just to be safe. Appreciate the support!!
@@GoFastRC How do you use the failsafe programmed into the radio? I just got a 2.5 and a 3.3 running again after sitting for years... both engines were locked up but run great now. I don't think my trucks have built in failsafes?
cool 👍
So how durable are those nitro engines? Do they require a lot of maintenance?
Yeah they require some maintenance. But it’s not super hard. Just have to to after every run or so.
How much run time do you get per tank on your 2.5 if your really bashing. I’m trying to figure out if I’m running to rich.
I usually get 8-9 minutes if I am temping about 240+. But when I temp around 220-240 I get around 7 minutes.
@@GoFastRC thanks that’s about what I’m getting
If my engine idles ive got 35 plus mins so run time about 20
Their is one more misconception tmaxx 1/10 and 1/8 is this are two different truck and what changes they had ??
What? Im confused
@@GoFastRC u can google tmaxx 1/8 model i Just want to know the difference between 1/8 and 1/10 because as i saw them they looks similar i don't see any changes
@@tej0skhairkar there are no changes, one is extended by a half in. The classic is shorter. They are both considered 10th scales
@@GoFastRC thanks you ✅
Do you run much electric? I see some in the background
Yeah i run electric all the time 😊
Ricky Bobby “I don’t know what to do with my hands”
Great movie 😂😂
im confused... I have a 3.3 and our 3.3 if completely different...
t maxx 3.3 and t maxx classic two number one and they are the gods and nitro rustler.
It’s also wider so from and back and not same
I have a tmax 3.3 ive gone through 2 engines, im looking at converting to a 2.5 as i picked one up cheap would it be ok with the 3.3 trans?
You could get a OS 21tm, they are way better than the 4.3
t maxx 3.3 and t maxx classic they are the gods.
That 3.3 air cleaner is scary. That engine is eating dirt.
It’s a 2 element filter. The inside filter is really clean. But it could use some cleaning. Appreciate the support!
Hey bro!!! Great vid!
Thanks dude!!
t maxx 3.3 number one.
I love my t maxx 3.3 so so so much.
traxxas is the number one and traxxas is the god and they are king rc car and they are best.
t maxx 3.3 the king and t maxx classic is the queen and nitro second.
traxxas t maxx 3.3 sick and t maxx classic sick and nitro rustler sick and traxxas is sick.
Thanks. Just got my first nitro, Tmaxx 2.5 classic. Any newbie warnings?? Do these things have any fire or explosion issues? Is it safe to take falls, jumps and tumbles, with flammable liquid inside?? Lol 🫤
I love traxxas so so so much.
t maxx 3.3 first best and t maxx classic second best.
t maxx 3.3 my baby and I love so so so much.
some very incorrect information was included into this video.
❤🎉😮😊ไฟไฟแอด์
3.3 is not 2hp.
👍
t maxx 3.3 be out forever and t maxxx classic be out forever and same nitro rustler.
What the hell are you doing with your arms
Um moving them??? Is it that hard to tell??
