View Full Version : Traxxas Revo; my first thoughts

Prior to the actual release of the truck, I was basically convinced that this was just another money-pit truck that had little use other than getting people into the hobby. Surely all the media hype and the fact that it was named "2004 Truck of the Year" prior to its release to the general public didn't help any of these notions. Afterall, we saw the exact same act play out 5 years ago with the T-Maxx and look at what kind of money it took to make the truck somewhat durable. After driving a TON of T-Maxxes, from some well kept and hopped up trucks to some of the most beat to hell Maxxes on the face of the earth, I wasn't expecting the Revo to be all that everyone made it out to be.

When the box was first cut opened this morning, the truck was sitting next to a LST. Initially it was agreed that the truck didn't seem to live up to the hype. After looking it over, it was very evident that the Savage, MGT, LST, Mammoth, and Titan were built much beefier in most areas and there was a lot more material in places that mattered on the truck such as the arms (although the engineers at Traxxas did do a much better job redesigning and reinforcing with what material they did use, keeping weight to a minimum). Armchair engineering isn't an exact science but it was somewhat disappointing to see that Traxxas didn't follow suit and try to build similar to their competitors.

All of this changed after a few tanks of tooling around during break-in. I initially felt that many of the magazines' initial comments were a ton of corporate BS when every one said that this was the best truck ever. It was hard to imagine a monster truck that actually handled consistently and predictably out of the box....until now.

I've driven a large majority of the trucks in production right now and this thing easily out handles a large majority of them. Maybe its the truck's lighter weight combined with the super soft suspension out of the box and the lower profile tires, but this thing turns on a dime. The dual steering servos make steering and countersteering in turns a breeze. Infact I would be willing to bet that this truck turns as good out of the box as any T-Maxx (or any truck for that matter) with an upgraded servo saver and servo.

As for climbing, this truck also does that very well; infact as well as the larger Savage. Three to four inch tall obstacles were no problem and the truck's suspension easly kept the rubber on the ground. The one thing that I didn't not like initially is the fact that the truck jumps like a T-Maxx; NOT level unless you correct. Stiffening the suspension would defiently help a lot considering the stock suspension is a little on the soft side and obviously aimed for the track.

I was also pleasantly surprised with the 2.5R. From past experiences with the 2.5, most of them always wanted to run hot on the T-Maxxes due to the weight of the truck, even when both needles were at factory settings and the carbs were sealed. With the needles pretty rich at the factory settings, the 2.5R had a TON of get-up-and-go and it never temped beyond 240. I'm really hoping that this is how this new breed of engines run.

I cannot comment on the durability right now, but hopefully tomorrow we will get to see what the truck can do. At this time, the only downfall I see to this truck is its durability. Maybe Traxxas threw us a curveball, but I see it kind of hard to believe that the arms are going to hold up to some of the serious thrashings that myself and others have put trucks like the Savage and MGT through. On a positive note though, the ONLY thing thats looks like its going to ever break in a crash will be the suspension arms and those are easily, and cheaply, replaced. Everything else looks like its very well reinforced with either metal plates or webbing.

I will post more updates tomorrow, but from a first glance it looks like Traxxas produced one heck of a new truck.

Nice write up, did you happen to take any pictures? If you want I'd gladly host them.

Edited - Please avoid using the quote feature when it isn't necessary. There's no need to quote the post directly above your post, especially when it's of considerable size. It's a waste. Thanks

I'm going to get some pics tomorrow along with some video of the beating that will follow (afterall you can't say a car/truck/buggy is good until you see how it withstands the inevitable :cool: ). The shipment was unexpected so I wasn't ready with a camera. I really appreciate your offer and I'll let you know tomorrow evening if I will need to take you up on it.

ATM works at a Hobby Shop I always go to. I'm sure he will be willing to tell what shop but if he isn't I will let him decided. He is very knowledgeable. They have an LST but I don't believe they have ran it yet. I could be wrong though. ATM Hopefully I will be able to make it up to see it run today. I will call to see when you are going to because I have sparring today.

I just got back from the LHS where ATM works.
My initial thought about the REVO is it is nicely done. The left side of the truck is much heavier then the right though and you can actually see it in the shocks as the left shocks are compressed more than the right. The 2.5R is nice but it doesn't have that much low end grunt. It starts off slow and then all of the sudden starts picking up 10,000 RPM into it. It has a very low center of gravity but the suspension is way to soft. Leading to a lot of body roll which makes it want to flip over during high speed cornering(I should know I flipped it :D). The engine also ran very hot at one time it was at 307º. We richened it to above suggested break in settings and it was running at 270º. There could be an air leak, but I left before we checked. I'm sure ATM will tell you if there was. It had a nose down attitude when jumping. Again that was probably do to the suspension being so soft. The drive shafts are gigantic and I don't think they will break. The optidrive works well but you have to have the brake on for it to shift into reverse, even if you are at a dead stop. While we are on brakes they work very well in the initial couple minutes before they are hot. Once they get hot they fade and the fade fast. It was taking 40-60 feet maybe even more, to get it to stop from 35-40mph. The brakes also get very hot. After one run they were in the neighbor hood of 170º.
But all together I am impressed with the truck. The transmission works well, the suspension is amazing just too soft, the tires are great, the engine runs well ,but hot. That's how the old 2.5's were too. It is fast and handles great at low speeds, but at high speeds it has to much body roll. It seems as if it may be a little hard to work on because of how cramped everything is in the chassis. The shape of the chassis is great. The REVO is a nice truck with many great features, but with some rough spots. It needs stiffer suspension, that can be taken care of with oil or springs. The left side(engine side) is a lot heavier than the right side. The brakes work great in the beginning, but fade soon after. The engine runs hot and is more of a high RPM engine, and it jumps nose down. That's what I think of the REVO.

thank you. now those write ups are short and sweet. both good and bad sides are reflected. very nice guys.

interesting....

so overall sounds good, or at least far superior to the T-maxx...

also the problems reported by both of you seem to be fairly minor given the aftermarket support that there is gonna be for it - stiff springs, better brakes and maybe alu arms(or ????) and it should be great....

let us know how it holds up to abuse...erm...I mean bashing..... :p

Sweet man, IMO that was the only part of the RCCA article that I thought might be a stretch, and that they didn't really change the engine much. Good to hear it meets up, a lot of people complained about how hard the 2.5 was to tune.

I've heard time and time again that it looks weak and is going to break, but the few who have seen the track demos or had hands on are surprised. :D

Keep in mind that the REVO ATM and I talk about are the same exact REVO and tuned by ATM both times. Then only reason I put mine was to give you a different view and tell you how it was doing after break-in. I'm sure ATM will get on here when he has a chance and right what he thinks of the second day.

Today's temperature/weather was a little different from yesterdays and break-in was also completed on the truck this morning, thus allowing it to be ran at full speed. The new head defiently helped, but the 2.5R still runs a little warm; 270 seemed to be the magical number for where the engine wanted to run pretty good. Like the 2.5 though, about 3 3/4 - 4 turns out from closed is not only the factory reccomended settings, but it is also a very good baseline needle setting for the HSN once the engine is tuned in.

Also as mentioned before, there was a slight fade to the brakes. I'm sure my going from 0-40 then slamming on the brakes had nothing to do with it though. :D I'm willing to bet that losing the spring on the brake linkage will surely help remedy this since it has done that on every other monster truck on the market. That was also the first charge on the receiver pack so its very possible that it needs a few more cycles until it reaches its peak capacity and voltage, thus maximizing the performance of the electronics.

No matter how anyone argues, the truck is a friggin rocket. Defiently add "out accelerates" to the list of "outs" that the Revo does over the T-Maxx. After about the first 10 feet once you punch the gas, the truck is gone. This may not be the best if wheelies are what you're going for, but on the track, that will probably make the truck easier to drive since less throttle control will be required when first exiting turns.

Even after these very minor downfalls, its hard to aruge that this truck isn't a winner (not to mention that these are really the only gripes I have about the truck, and even then its a longshot to complain about them). There were also a few decent cartwheels towards the end of the day and the truck held up without any trouble. Considering all were on pavement and at speeds above 20-25 mph, I think that says a lot.

What were the weather conditions? Temp and humidity? Not exact numbers because I'm sure you don't have a weather station at your side, just an estimate.

prolly 73 and 62% humidity. i live within 15 miles so it should be about the same.

guys, whats the maximum operating temp. of the 2.5R? (as per REVO manual)

oachalon

the maximum operating temp is 270 degrees. I dont know why your having temp problems with your revo. My revo is running around 220-240 degrees with tons of power and me beating on it. I love this truck.

07-17-2004, 10:58 PM
To answer your question Steve, it was mid 80s on day 1 and mid 70s on day two. Both days humidity was low and the truck was running on Traxxas 20% Top Fuel. I'm wondering if possibly this truck had a loose piece of plastic in the tank and maybe that was causing a small clog somewhere along the way.

StevePond
07-18-2004, 12:04 AM
Hmmm. That does seem a little on the warm side. I think these engines run better when they're a little hotter than the average engine, but I'm not sure it should be that hot under those conditions. Keep us updated and thanks for the info.

ok well i was just looking through the august issue of a unknown Xrc magazine and it said the top speed of the revo was 38.8

Steve do you think that is right?

Oh my god!! The revo doesn't break 40, must be a crappy truck. Because we all know that top speed is what determines the winner while racing. Proof of this, nitro 4tec because it can do 60mph out of the box. That must mean it is the best, even better than the FTNTC3's and serpent 410's.........

hmm if its top speed that makes a good truck all mine must suck...... :rolleyes:

course being able to stop, corner, jump, and accelerate etc (and not break) would be useful too......

:p - I do hope you were kidding of course.....

Mad Matt - "Traxxas bashing"? did u intend the pun? lol
