- In this video, I'm sharing the first run in 10 years of my nephews Traxxas Revo 3.3 RC Nitro Monster Truck! I can't believe it's been that long, it feels like just yesterday he was driving around with this thing! I will also be running my new Revo 3.3 for the first time too.

The high reving sound on the red one, is most likely the slipper clutch on the spur gear needs to be tighten a little. And as someone else wrote her, the one way bearing needs to be cleaned from old gummed up oil from fuel. Do that, and add some fresh oil on it, and i think your good to go. Sometimes these nitro engines leak from the front bearings on the engine, and that can be the source of the oil spill you mentioned, or from one of the fuel needles. This can make the tuning much difficult, and leaning out the motor to much. Nice video, and great trucks. 👍
Yes it was the slipper being loose and now shifts into 2nd with ease after adjusting. I'm going to service that bearing before I send it back to my cousin. Thank you.
the revo 3.3 was my FIRST rc ever! I still got it to this day but its all in parts now lol Great video man, i came across it cause im thinking of getting back into rcs and searched revo 3.3. I havent done anything with them in a long time. Great video, i always had a makeshift battery bank to plug the igniter into because that little battery dies fast.
That's awesome! It's starting to warm out in my area so there will be lots of videos out on these. Thanks for checking out the video.
@@nwirc The second one took forever to start. I'm glad it started. I'll be sure to check out more of your videos
Red Truck, check the friction pegs on the slipper. If they are good, give it a bit more tension on the slipper. Also, clean the one way bearing on the electric start. If that doesn't work, replace the one way bearing.
I personally can't stand the electric start on these, and replaced mine with a traditional glow starter, and pull start.
I just cleaned the one way bearing the other day and it starts right up now. I also sprayed wd40 contact cleaner into the brushed motor and applied bearing oil on the tips of the shaft ends. I also found out the slipper was loose.. I tighten it up and backed it out about 1/4 and now shifting like a king.
I'm heading down south tomorrow to return this beast to my cousin so he can enjoy it after all these years of it sitting.
The starter isn't working because the one way bearing is either dirty or dry. Clean it with brake or carb cleaner and reassemble with motor oil. Mine functions perfectly after doing the same.
I replaced the oneway and it now works great.
great info! I gotta do this to mine its sorta the same
The very first things to be be done on these is, replace the bearings and carburetor. I use the fast eddy bearings, they work great. OS 11k carburetor. Break in 6 heat cycles before putting it on the ground. Thats about it. I have six of these because I like the platform. Nothing in any of mine is traxxas at all anymore. Servos, radio, engine all changed out. Rpm swing arms, the whole nine. Now they are worth a shit. That gear is a easy fix on the ten year old. Slight adjustment clockwise in the transmission. But it sounds more like the slipper.
Thanks for the info. It was the slipper and now shifts great. I heard that OS carb was awesome on these 3.3s.
Awesome. So buy a $500 RC and immediately add a $150 carburetor and replace all the bearings. Great advice bro
10 years ran good
I had to go through it first but it was worth it.
Just got mine out and running too…was a PITA to find an affordable transmitter for it! I had everything else except that for some reason.
It has been almost 10 years for me too.
@@jeepjeffy04 That's awesome! What transmitter did you go with?
@@nwirc The same as the factory original (2230). I guess they are still being made, but are $160. I found a new old stock on ebay for $100. I bought a new TQ from a local hobby shop and it doesn't work with the old receiver.
Nice..
The one way bearing is going out that's why it's slipping when trying to start. I had a Traxxas Tmaxx do the same thing. Changed out the one way bearing and it's grabs start turns with no problem.
Thank you. I have the bearing ordered and plan on replacing it soon.
Yeah also, you might wanna replace the engines back plate and starter shaft with the new one way bearing. Due to the fact that it to gets worn out. After the engines heat cycles and nitro fuel run time. It will engage and contact with the one way bearing replacement like it's new again.
Where your tune was after the first adjustment was much better
I have a old school revo I rebuilt
It’s got a 4.6 engine and eBay Steele forward and reverse gears.
I have never had a 3.3 bed in ever. And Ive owned probably 5 so far.
The piston where the con rod mates together is weak
Awesome vid dude. Runs perfectly.
Ohhh that wasn’t to warm.
230 degrees is where you want the temps to be
170 is to cool. 😎
Yeah I'm looking into getting a new temp gun the one I got is just all over the place with the numbers. Thanks for the info.
To answer your question about the starter issue, the wand is where your issue is. If you take the wand apart you will most likely notice a lot of cold solder joints, for some reason 9 out of every 10 of these wands seem to have the cold somder joint issue and will most of the time just cause the glow plug section of the wand not ro work but in sone cases it does have issues like you mentioned. If you decide you want to fix this issue all you have to do is take te wand apart and redo all the solder joints. Good luck
That's some awesome advice! I have 4 of those wands and will redo all the soldier points. Thanks
There is dried up oil in the one way bearing. Take it out and put the one way into a cup filled with methyl alcohol. Shake it up and the oil will flush out
It will clean out and grab nice. 👊😎
I'll have to try that out. thanks for the tip.
Your wands faulty connection is design flaw by traxsas. That connection gets full of dirt when we run these things. I made a plug for mine no more connection problems👍
I'm interested in knowing how you made your plug. I like the idea of what you did.
I’ve never had this problem but it’s probably a lose wire check the ez start motor and the power wires they slip off sometimes
Sweet idea for the plug 😎
The power wire fall off the ezstart motor sometimes for me lol
There should be a hole on top of the transmision. Just move the Revo forward until you see the hex pin to make it shift sooner or later. One time I turned it too much and it stopped shifting into second gear. Had to turn it back the other way again.
It ended up being the slipper.. I tighten it up some and it started shifting into second.
New Revo sounds like she’s running sweet!
I agree and will lean her out in a upcoming videos. I will get the red one dialed in soon. I do believe the slipper is slipping but who knows. I'll figure it out..
@@nwirc Cold n wet here in Texas. Hopefully I can break my Revo after Christmas. We usually get warm spells…
@@Drumbone71 These Revo's are awesome! I'm really enjoying how plush the suspension is on these beasts.
cool rc's and great runs
Thank you.. Working on some issues on the red one. I do believe the slipper is slipping. You can hear it in the video towards the end of the run.
Great truck run perfect
Thanks. I was able to get the red one to shift in second gear the next day. The video is out on that one.
It's the one way bearing. On the red truck you'll have to take the starter off. But look online or ask your local hobby shop they will show ya. And there is an adjustment on the transition and online or in the manual it will show you how to adjust the transmission for shift timing.
I replaced the one way and that part fixed that issue and the slipper was loose causing not to shift. Thanks
Wow. That is cool. I have the same 10 yr old model. I bought from freind 1 yr ago. I found that you need to prime the motor a little more before starting. I have a pull start on mine. Check your transmitter on the 50/50 or 70/30 setting. Using the 50.50 setting it should shift sooner.if your trans adjustments are good. Cool video.
Yes.. I was informed to prime these 3.3's every time I go to start them and it works every time I did.. I will get videos on this soon.
I need to get my nitro slash running again it’s been about 4 months
Heck yeah.. Fire it up and have some fun!
Will do waiting on this weather to warm up
Yea man don't lean too much, the rod will break. I fucked up and did that but rebuilt and good now. You're smart monitoring heat.
Oh man that had to suck. I'm not sure about this heat gun I got It's just a cheap $12 one from Amazon. I'm looking into getting a better quality one just in case. Glad to see you got it rebuilt back running.
To the comment on the con rod. I also ran low on fuel while running full throttle, and went lean, and the con rod broke at the piston. And slit in half. And put a hole in the piston, I had a back up motor. So rebuilt it. Just run the car on the rich side. And don't let it run out of fuel. Been running great since then.
If you're grtting overheating and high high temps lean it out counter clockwise like the video 🎉
I really need a new heat gun. I ran it off video with my buddies temp gun and it wasn't running hot at all. Thanks
The negative pin in the wand melts and moves up into the wand
I'll be taking all of my hands apart and redoing the soldering joints and will check that negative pin. Thank you
Those newer EZ Starts don't always properly seat in the connector on the truck. I had to expand the female connectors in my EZ Start box to get it to properly seat every time.
Thank you for the tip. I will look into this soon.
I just bought a new jato 3.3 and one of the pins for the Ez start was not lining up with the starter so I just bent it with a pick until it worked every time,
I'm going to take mine apart and see what I could do with it as well. Thanks for the tip.
Your using the temp gun wrong! Point it straight down towards the glowplug in order to get the best readings.
I'll keep that in mine. I'm usually all around the engine thinking I was good. Thanks for the tip.
Sounds like it's the the one way bearing in the electric starter is slipping
That was one of my guesses and will see about replacing it soon. Thanks
The red one the slippers slipping
Yes it was definitely the slipper and now hits second gear.
@@nwirc
Sweet that’s great.
I just did up a second transmission with the center diff and the rear brake kit. Also for the big block build.
It’s such an amazing platform. There’s big hopes and Mabey something coming for the revo in the next little while I hope.
While the hobby’s a rocking we all have to come together and make it better.
It’s so nice to see more oldies being made great again.
Rock on bro keep burning nitro 🤘☺️
@rcsendandblast1579 Nitro will never die in my eyes! It's what had gotten me hooked over 40 years ago. Like you said, we need to stick together and push these companies to make more!
You have to hold your EZ start straight up and down
Thanks for the tip. I've been noticing that but didn't think it mattered. Thanks
that is the one way bearing slipping on start up/also issue with the clutch not fully engaging
I fixed the issue by tightening up the slipper. Shifts great now..
Check the one-way barring
I bought a new one and that was the problem. Thanks
I have a current issue with it not starting found a short in the hot wire (red from the starter) check for contact and damage to wire. Converting back to pull start
I ended up buying a new oneway bearing and that fixed the issue for mine. I'll end up going to pull start I'd this was to fail me again.
I had one and the transmission messed up and the truck was never the same after I had the broken parts replaced in it
I got real lucky that all my issues was small adjustments to get it working.
I can say when it was running good I had a blast not to mention it is the only nitro truck with reverse gear,
one way bearing is slipping in the ez start system clean it with nitro cleaner! or buy new one
I went down south and returned it back to him. He lives over 500 miles away from me. I have the parts and just wating for the next time we meet up so I can install them. Thanks
Did you figure out the starter issue?
I didn't mess with it yet. First thing is I should have primed it first. I'm going to take the starter mechanism off an clean it and see if it will stop slipping.
one way bearing clean it
I ended up replacing it with a new one but cleaned and saved the old one. Thanks
What are the factory settings?
The low speed flush with the body and start with high speed 4 turns out from closed.
It’s not the starter. It’s typical traxxas for you. Pretty normal man.
Thanks for the info. More than likely l will install a pull start when this starter gives out.
@@nwircGood idea, for these, all I use is pull start. Also, I was going to mention. Make sure you prime that engine before starting. It will start so much easier for you.
@terryshrives8322 Thank again. I'm new to 3.3s and will take your advice. All my other nitros would practically prime themselves within seconds.
FYI Your idle is to high !!!
I fixed that after the video. It's runs awesome. I'll get a updated video out soon. Thanks
Autel thermal imager part number ir100. Pricy but worth it.
Oh my! Way to rich for my blood at the moment but will keep this in mind. Thank you for the info.
