7 Traxxas Revo 3.3 Upgrades:
People owning the truck tend to upgrade the servo, tires, motor, and rear A-arms. But the truck is pretty agile out of the box.
If you’re still unhappy with the buggy, maybe this is not the car for you. Or if you still want to stick to it, here are more parts for you to upgrade along with the suggested ones.
1. Servo
The stock servos from Traxxas are dual digital ball-bearing servos that are waterproof. They come with 250 oz.-in. combined torque. These servos are quickly responsive and all. But they tend to go bad after a few days to a few months.
There are tons of options for better servos. This includes Savox, Hitec, Ace/AE, and many more. The Ace/AE 1015’s a good option to have with single servos and throttle servos moved forward. For 1/8 RCs Savox works the best!
The throttle and reverse servos stutter when the car is being taken in reverse. They are also quite slow in terms of response time. They should be upgraded. In this case, the brands I mentioned will work fine.
The steering servo rarely needs upgrades, it is quite good.
1st Option: Savox SW-0231MG Waterproof
2nd Option: Hitec 35645S HS-5645MG
2. Motor
The stock TRX 3.3 engines aren’t so bad. They are pretty reliable, especially with proper maintenance. Most people do not like the EZ start system by Traxxas. What you are looking for in a motor is the best top speed. Big blocks are not necessary for a Revo.
Back in the early days, there had been the Piccio 21Max, Sirio 18, Sirio 23, and many more. Currently, there are only a few.
The Dynamite Mach 2 .28 Big Red is the recommended motor. An O.S. 18TZ that comes with a crank from an 18TM would be nice. But whatever you do, stay away from the Dynamite .19. They come with bad rear bearings. They will go out. They will also damage the sleeve, crank and crank journal.
The Picco 26 Max is a great engine. Although their carbs aren’t the best thing ever. They also tend to eat on the bearings.
The O.S. 21TM, RB TM523, Sirio S27 are nice engines too!
3. Transmitter-Receiver
The 2.7 MHz transmitter and receivers are huge. They add a lot of extra weight to the truck. They also have an obnoxiously large antenna. Whereas the 2.4 transmitter and receivers are pretty compact.
Other than that, there isn’t much need for the radio upgrade. The Tactic TTX300 SLT 2.4GHz 3-Channel RC Radio System is also pretty cool.
High-end Suggestion: Futaba 4PM 2.4GHz 4ch Surface Transmitter w/ R304SB Receiver 01004388-3
Regular Options: Spektrum DX3 Smart 3-Channel Transmitter with SR315 Receiver SPM2340 Radios 3
4. Wheels and Tires
The tires are going to be a huge investment. They are one of the most expensive things. Skinny tires with big dish wheels are what you are looking for.
The stock Revo tires are the Tall Geode wheels and 6.3″ Maxx-sized tires.
Picking skinny tires is necessary if you‘re racing in the mud. Mud and sand are going to catch on.
One of the tires I suggest are the Pro-Line Hole Shot 2.0
6. Wheelbase Rear A-Arm
You should look for something that provides stability to your nitro. And this is achieved better out of Traxxas extended wheelbase rear A arms, in the place of any alloy parts.
The A-arms help with stability. They are readily available and are fairly cheap. So even if they are broken, they are easily replaceable.
Another option is RPM arms. Yes, they might be a little pricier. But that is about the only issue. Besides, they come with lifetime replacement. So there is no charge even if they are broken.
Usually replacing these are around $40-60
7. Battery & Charger
Stock batteries are usually 1100mAh. The stock engines should last quite a while. Especially if you’re charging it every time after bringing the thing home.
The thing with Revo batteries is, after a while they get slow. They only run 45-50 minutes and that’s it. This is mostly seen in the NiMH packs. So you might consider LiPO batteries. There is some really good brand LiPOs in eBay. So you might want to check that out.
A good battery for the transmitter will increase your runtime. Maybe you’d like to hit bigger mAh? As charging is the key to peak performance, I suggest getting a Traxxas peak charger.
If you really want to manage your packs, I have the Triton chargers (with programmable limits). They will really manage your packs. But yes, they are very expensive. The Traxxas charger is a good affordable option.
Traxxas Revo 3.3 Accessories Upgrades
One thing to change is the air filter. It doesn’t give a performance boost if you go with an aftermarket version. But it does increase the health of the truck. I would suggest a two-stage filter with the engine.
Another upgrade is a lighter throttle spring. There is a visible improvement in the throttle response. It is faster too. It works well with the mods of RPM A-arms, bumpers, and axle carriers.
Another suggested upgrade is changing the stock plastic carburetor. Instead, you can install the Losi 3.4 carburetor. It will cost you around 50 bucks. This improves the tuning, making it a lot easier.
Conclusion
Traxxas Revo 3.3 is a good RC truck for peak performance. It also provides much scope of upgrades. You can get as creative with it as you like!
Of course, some parts are a bit expensive. More than you’d think they worth. But they really are good parts and support a pro upgrade. So I would suggest you make this investment!
