How to make the Traxxas 2.5 & 3.3 Engines 100% More Reliable

[@anthonyaviles8665]

I did what you said and added a os glow plug and now the truck is a complete different it starts right up and the tune is pretty good

[@TraxxasGemini3.3]

Os 11k carb (or losi 3.4 carb if u can find one.. tunes much better and more power.. direct drop in) Os 21tm header tuned pipe (plastic muffler is a joke trash it! The resonator is ok but better are out there.. ths racing, novarossi, and ercm are really nice) forward only conversion ( fairly easy to swap in... makes it stronger, simpler, and rev faster if u wanna lose reverse) Os LC3 (Hot) or Os LC4 (medium or cold) plugs are great Run a good 30% nitro in 8-12% oil content (over 12 holds too much heat in and makes tuning harder than it needs to be.. 30% nitro 10% oil is a good blend with 30% nitro 8% best u can get.. higher nitro content u run it richer, and u get even more power from it!).. VP, Bones Brew (that was THE BEST!), Sidewinder, and Morgan are good fuels (Byron's back in the day oh man was in a league of its own of awesomeness!) Engine swaps (os 21tm is best but takes longest to break in and its expensive.. dynamite .19t lil more than a 3.3 on warranty cost wise but lil less down low than a 3.3 yet more top end than a 3.3 and it's overall better made just needs a more durable backplate and starter swap then it's golden! And a modded 2.5r is another awesome engine! 3.3 are hard on rods splitting em, pistons can shatter I have one that did.. 2.5r is better built to handle itself but with mods it'll really shine in its own.. also quick mod for a 2.5/2.5r pull stock 2.5 crank out for a 3.3 crank it's a direct swap it'll wake up your 2.5 engine).. Chassis parts.. rpm parts always a good choice (bulkheads, arms, braces... it's all bolt n nut together be patient with it and have tools.. it's very solid and it'll make any t maxx a mini savage!).. check me on fb (Erin Kavanaugh) I've my rc on there and I can help you out with advice!

[@kevinduong7674]

Do you have a link to buy the Losi carb?

[@motorbreathjz]

@@kevinduong7674 you dont need a link. he told ya what it is.. losi 3.4 is the engine.. i dont even think they make it anymore..

[@weewick7779]

So to summarize. Use good fuel, get a good cooling head and get a glow plug and igniter

[@Troubledboy88]

The EZ start can light the glow plug up just as hot as an igniter. The problem is, there is a few places where it can get corrosion, or old fuel around the contact point can be problematic for the connection. Btw we both live in Idaho

[@Darus2013]

I just started my Revo 3.3 after 10 years of not running with 8 year old fuel and it rips!

[@promxrippa]

Literlly did the same with my t max just sprayed some wd40 down the guts and she fired up

[@Spooky4815]

Same

[@RogerJohnson-j9v]

i switched to the VP fuel as well and the truck seems to be running better

[@ManuelOrtizification]

OS plugs, yes. Different glow igniter, not needed with the OS plug. Less oil, no. The traxxas motors love extra oil. Also your idle is super high

[@joshmatthiesen4552]

Good video. But I disagree on ditching the EZ Start glow plug wire. I have a Revo 3.3 and don’t have any problems with it. Other than my starter motor burning out. I even upgraded my starter wand to use a 2S lipo battery

[@The72birdman]

Seems like some good info. Thanks for sharing.

[@Duckhunter_Gokillembirds]

I’m up in north Idaho and I have a tmaxx so same truck, same state, and same area of the same state, we should hang out where you at couer de lane, Kellogg, pinehurst, post falls? Where you at cuz we now friends

[@TheHobbyistRc]

near cda

[@design2survive]

Near sandpoint..just picked up an old revo 2.5..need to do a N Idaho rip! I normally fly planes..but this nitro car is pretty fun.

[@zachattack2016]

Os11k carb and aftermarket rod

[@josephfast5887]

And ditch the electric start and ez wand system

[@TheKerstingm]

What tires are you running on your Revo?

[@allanthomas3861]

What kind of remote did you use? I have a T maxx nitro and need the remote that controls the 2WD & 4WD

[@TheHobbyistRc]

I use a Spektrum DX5C.

[@motorbreathjz]

there isnt 2wd and 4wd gears in a tmaxx lol... its 4wd all the time. the only time you need a 3 channel is for forward and reverse tranny..

[@Mrvoorhees01]

Thanks for the info. what did you do with the blue plug wire? Just snip it? Or tuck it away somewhere

[@TheHobbyistRc]

I just tucked it away from anything that got hot.

[@ironhead320]

Alot of the other fuels have 12-14%oil that's to much.I been useing vp fuel big difference with that fuel

[@DerekRC]

Helpful tip your idle is way to high.

[@Rcforlife]

What's the tune for your bc my dad's keeps dying when it's idle

[@mr.notsure9679]

Yo dude, I'm getting a lot of interference with my stock radio and receiver. I don't know what you have, but what do you recommend I should switch to? My Hobby shop guy isn't that great and just knows to sell me what's in his shop.

[@TheHobbyistRc]

I'm running a Spektrum system in my fleet. Dx5c radio and a variety of different receivers. I've never had any interference with that system. If you want a budget system, I'd recommend the Dumbo Rc Radio system. The transmitter is affordable, the receivers are cheap, and they are famous for having excellent range.

[@mr.notsure9679]

@The Hobbyist Rc thanks for the info 👍

[@chuckwalters4759]

Can I use this long plug with a stock head?

[@arturos.l.2248]

Hey the reason youre blowing so many Glow plugs is because you ran VP fuel without richening the fuel mixture. The traxxas top fuel has much more oil than the VP. In the long run, youll foul out way more traxxas glowplugs with that type of fuel, and the OS ones will foul too, but they'll last longer. Your engine appears to be running a little lean btw. Avoid tuning the carburetor a lot. Try not to make large adjustments where you have to unscrew and rescrew the needles, the carb is very fragile and gets damaged easily by this. Its better to leave these traxxas carburetors Alone for the most part and use traxxas fuel, and leave the idle reasonably high to compensate for the rich fuel mixture going in. Since youve already run it this way for a while i recommend just seeing how long it lasts, then buying a New, non traxxas engine with a base tune carb

[@hilham89]

I think that you ment the head would fit the 2.5 and 2.5r. If its for a 2.5 it wouldn't fit the 3.3

[@randomworld75]

I think you meant the glow plug is an LC3, not "ic3". You can also use the OS LC4 glow plugs. It's more of a medium heat range.

[@yosvanisleyva7028]

I buy one and I just wanted to know if it has a reverse

[@TheHobbyistRc]

It does.

[@StephenBrewer89]

Hardened spur gear, Billet transmission case. Steel gears and a reverse delete are mandatory in my book. As well as billet front and rear diff housings. Just from my experience.

[@LameduckArmyOF1]

did you mean lc3 glow plug? there is no ic3

[@OU812NVME]

Wow I've been using 10 percent fuel for over 30 years and not had a problem maybe that's the issue...... but I know you guys want to go as fast as you can

[@2578136]

Why isn't it shifting to 2nd

[@Carguy-fn5nf]

Its the 2.5 it doesn’t have 2 speed

[@PriusTurbo]

⁠mine does

[@mkesrs1]

HIT SECOND GEAR!!!!!

[@jamierusso5730]

t maxx 3.3 number one and it the god.

[@johnoyler6028]

the traxxas 2.5 and the 2.5r is the same engine the difference is the blue head

[@dredennis113]

The glow plug threads into the head.

[@andyfrancis5277]

Modify your ez start to accept a lipo, no need for a seperate ignitor. Traxxas fuel is garbage and you replaced the cooling tower, not the head. Idle is too high and I never heard it hit 2nd gear, that is adjustable too.

[@motorbreathjz]

he replaced the cooling head. theres no such thing as a cooling tower.. there isnt any modification needed to use a lipo battery in the wand.. you just plug the dam battery in the wand..

Oh my goodness!!! Hehehe hi buddy

[@britishpitbikerider1783]

I swapped my glow plug for dynamite, boom.

[@raywalker2938]

Two Speed ?

[@TheHobbyistRc]

It’s there, I’ve just been having trouble getting it adjusted correctly.

[@josephfast5887]

@@TheHobbyistRcit’s not getting up to a high enough rpm to shift gears.. lean it out. Especially if ur running under 20 fuel. When it does wheelies instantly when u feather the throttle then it’s good. Your runnin rich

[@motorbreathjz]

@@josephfast5887 you mean richen it up? it sounds too lean as it is and theres little to no smoke that we can see from the video... .... and his clutch adjustment is probably the issue with 2 speed... hes running 20% its right in the video.. why do you armchair advice nazis get so desperate to give advice?

[@glenlarson5373]

it starts easier because the idle is too high. baaaraindead

[@motorbreathjz]

ok and what if his idle has been high from the start and he still had issues before this, you never took that into consideration because.... ......braaaaaain dead you cant just turn your idle up on any application and have it run easily..
