How different is a Tmaxx 2.5 and a Tmaxx 3.3?? 

First!!

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.

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

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!!

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

Yes your right on i have both trucks love them both and your video keep up the good work 👏

Hey bro! You’re channel has grown so much so fast man!

Great video. Really appreciate the explanation of the differences.

Always great informative videos

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.

Great video!

In any case. Always replace the bearings and carbs first thing in either of these. You will be so happy you did.

So good!!

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

keep it up kid!

I have both battery powered and nitro RC's and by far my favorite are the nitros!

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

cool 👍

There is no replacement for displacement! Nice video.

Nice review.

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 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.

Nice video

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.

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.

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

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

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

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.

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.

I have both and I love them both and I’m not sure why! Lol

Hey bro!!! Great vid!

I’ve heard the 2.5 & 2.5R are a lot more reliable then the 3.3? Anyway great video 👍

The way you move your hands around reminds me of Scottt Kilmer

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?

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?

So how durable are those nitro engines? Do they require a lot of maintenance?

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 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 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

Hi Nephew. We enjoy your vids. Carm wants to drive cars with you.

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.

Do you run much electric? I see some in the background

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 🫤

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

Ricky Bobby “I don’t know what to do with my hands”

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.

Sooo Cool - Nitro -4- Ever Battery’s are for Flashlights

t maxx 3.3 and t maxx classic they are the gods.

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?

t maxx 3.3 and t maxx classic two number one and they are the gods and nitro rustler.

That 3.3 air cleaner is scary. That engine is eating dirt.

It’s also wider so from and back and not same

Their is one more misconception tmaxx 1/10 and 1/8 is this are two different truck and what changes they had ??

t maxx 3.3 number one.

❤🎉😮😊ไฟไฟแอด์

I love my t maxx 3.3 so so so much.

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.

traxxas is the number one and traxxas is the god and they are king rc car and they are best.
