i have a savage x i played with for about 5 months and got big into. tore it down to rebuild the diffs (pinions are weak) and never got it back together. trying to sell it if your looking to find something you can build with the upgrades i have available for it.

cant find the picture for it but i know the radio alone i bought for 200 lol. i could slive you a deal if you help clean my room out.

We've got one Nitro but its packing away in a box right now. We just moved in on the 1st of the month. Hopefully we can find ourselves a hobby shop in the area to we can get some glow plugs and a new glow plug ignitor since mine is pretty done for. Haha. This puppy is for sale to serious buyers. Got tons of parts and accessories. Few different clutch sets and upgraded. Gotta love HPI. This is the original Savage.

I just got into the hobby. I picked up a Traxxas nitro rustler ready to run for about 375... Sucker is pretty fast, just wish the weather was a little nicer so I could run it some more... any body got any good tech tips/ upgrades for these babies?

The only nitro I have is one of the original T-Max's. The other nitro I had (ofna mbx r2) I converted to brushless electric.

Not nitro, but you'll probably get a laugh out of this anyway... a few years ago a buddy and I did some speed tests on our brushless setups (approx 60mph) - don't try this at home!!! Tractor meet 1/10th buggy!!

I just tore into my rustler for a good cleaning.. I think im gonna go all aluminum because I do alot of bashing.. [I] was thinking of upgrading to the 3.3 motor but its probably to much power, instead gonna go to the 2.5R... After I roach the 2.5 thats in it now.. Hopefully it will run a while before that happens but im new to the hobby so itll probably happen sooner or later.. Any thoughts as to some good upgrades for me..

Those are a couple of the reasons I went to electric. I can fly in the morning :D

Also, the exhaust messes with my sinuses, I hate it. Once you go electric you never go back! So much power potential... Also, be sure to get after run oil for them engines, and do a monthly air filter change (depending on how much you run them). That'll keep the engines running nicely for a long time (or at least until they wear out after the usual 60 hours for Traxxas engines...) shens One of the employees at the LHS had a Losi truck from the 80's that still ran great, with the original motor, never touched.

03-23-2011, 08:54 PM

Yeah, make sure you flush as much WD-40 out as you can so it can fire up faster and not flood it- you just want a thin coating to keep things lubed.

Oh yeah, I forget which glow plug it is exactly, but there is an O.S. glow plug which you should replace the stock traxxas one with, burns at a bit higher temperature, which keeps your engine from gumming up.

As far as engine mods go, about the only thing you can do is run a different glow plug with different fuels. There is little to NO mods for rc engines, as they're about as high performance as it gets.

Exhaust systems are mostly for where you're racing. Some locations you'll want more getup and go, others you'll want more topend speed, and moreso a mix of both- the stock exhausts generally are good all around with a smooth linear powerband.

Unless you are a serious racer, you generally won't need to change your pipe. Re-gearing can have slight effects on engine performance, but again you won't need to re-pipe.

Nope, all we had in our repairs was Traxxas vehicles, because the A-Arms and gearboxes are flimsy (okay, we had an occasional HPI and AE truck, but they were because of other things). I can tune a nitro engine, I've ran them for my first 7 years in the hobby, and that's a lot of hobbyin in those years. I tuned engines on thursdays at the hobby shop for the guys who would drop their cars off for tune ups for the races on friday nights and saturday afternoons. I just prefer the power of electric- there isn't a nitro engine out there that can beat a properly setup electric power system. Nitro engines have physical RPM limits- electrics do not have RPM limits, they only have electrical limits, which is usually only reached in BIG power systems (we're talking 30,000 watts and 60+ volts, turning a 28" diameter prop at 16,000RPM's).

Also: I have developed allergies to the nitro exhaust, I can't breathe in a lot of it before my sinuses go nuts, so the main reason I run EP is because of health issues.

Luckily, I have no such issues with gasoline fumes :D

4 stroke engines have been around for models for a long time, but they have been SLOWLY creeping into the RC car market. The practical applications are in heavier trucks where the torque and power of a thumper is better for acceleration. They do pretty good on the topend too...

How about them gassers? Nobody has an HPI Baja 5B or 5T?

Been building and racing RC cars for about 18 years now, first car was a Kyosho Outlaw Ultima (which I still have) and a Kyosho Double Dare. I've had every kind of car you can imagine, rock crawlers, 1/10th stadium trucks, on-road, MT, 1/8th scale Buggy (which I still race) etc.

The back of my Jeep a couple of years ago:

Electrics are really fast but lame IMO, one of the things I love about RC is tuning engines and the smell of nitro. I hate charging batteries all the time and li-po is so expensive....

Here is a Tamiya TT-01 I sold a while back, I loved this truck but never used it.

Some nice machines, two posts up. I have one rc nitro truck that gets about the same amount of use as my R. Never left the house in months with them.
Anyways it's a Savage X 4.6. I put a venom fail safe with temp gauge on it and a pull cord. I didn't like the roto start. Besides that I just replace the spur gears, clutch, control arms and driveshafts that I lose often when I am playing. Might get it out for a spin.

Not sure what other hobby shops were like with traxxas sales, but I know ours went something like this:

HPI
Traxxas
Team Associated
Losi
Mugen

Then everybody else was pretty much down below. I know for fact that we had the largest Traxxas stock out of the entire county, we had multiples of EVERYTHING in stock for every car, and the moment we sold one item, we ordered another one. We had boxes in each order just specifically for Traxxas :lol:

inv3ctiv3

03-29-2011, 12:43 PM

Traxxas is the best beginner RC car out there, they are tough (most of the time) and easy to work on/get parts for. Every hobby shop stocks traxxas because they are so popular, as far as racing in upper division classes they suck but for a backyard basher they are hard to beat. Same with HPI, my Savage X is easily one of the toughest RC cars ever made, you almost have to try and break it.

Crossing your battery and servo wires across your reciever can cause a gliching problem....so can any parts "rubbing" on each other (like a mount rubbing a carbon fiber plate).....what kind of radio you running? (AM, FM or Spectrum)

Xpress

03-31-2011, 04:54 PM

Almost anything can cause glitching like you describe, so make sure all your nuts and bolts are tight, and make sure your antenna is routed away from servo leads. Also make sure the antenna isn't cut, removing anything from the antenna will cause range issues. There's a reason why they are so long.

With 2.4, make sure you've got your antenna(s) poking out of your Rx box and away from wires. The gasoline engines really futz with 2.4 systems, so running a receiver with a satellite receiver is the best.

I have a HPI Savage X that I got three years ago. I love it! I beat this thing and it keeps on going! I've jumped it 20 feet in the air and it drove away. Not saying its indestructable, Ive broke things but for the most part its pretty strong. The street car and the other truck are my friends. The Losi XXL is very fun, but it cant keep up with my Savage, most of that is because of the driver. I have been thinking about getting one of those 1/5th scale HPI Baja 5t's. The gas mixture sounds alot cheaper then the nitro fuel for 35 bucks a gallon.

RPM parts. DON'T buy the aluminum parts if you break the plastic ones. I've seen TOO many people think that the aluminum parts will never break, only to come back into the hobby shop the next day and demand a refund because they broke their front shock tower and right A-arm claiming I sold them faulty parts, even though they're the ones who ran it into a curb. Good thing we have our warranty returns on the receipt... $85 down the drain...

RPM parts are made of sturdy plastic, that can flex more than the stock composite plastic pieces, and also resist vibration a lot better, ONTOP of the lifetime warranty. Yep, you break a part, send it into the manufacturer (or bring it back to the LHS) and they give you a new one :)

I've been out of cars for a while, they got boring to me when I got into planes. I still have my XTM MAMMOTH that is waiting for some small msc parts and a radio system... Some day...

Oh yeah, a lot of Traxxas stuff is crap, really, especially the gearboxes in the REVO, JATO, and all of their electrics. We had about 15 REVO's and JATO's on our repair shelfs waiting for tranny rebuilds.

If you honestly want something that's FAST, and has a lot of PUNCH off the line, then get electric. We're currently over 160mph, nitro ain't got nothin on us! :lol: :naughty:

Totally disagree with Traxxas stuff being cheap. I run exclusively Traxxas at this point and the electric trannies are beefy as hell. Only thing that ever breaks in there is a little pin since they are all metal internals. If you are messing around Traxxas is by far the way to go. WAY better parts support than any other brand. HPI is next. Associated and Losi don't make good bashers either. I will agree electric is where it's at. I work for a company that makes glow plugs and starters and all that good stuff, and I would still not go back even being able to get that stuff cheap.

I am aware. I bet you didn't know the creator of CA died late last week either ;)

CA's come in a BIG variety, ranging from thin CA's that flow like water, to THICK CA's that don't flow. They also come in GEL forms, tire glues (which generally have additives in them to help them bond the rubber to the plastic rim- doesn't form a brittle bond, which is why the tires won't seat properly if you use regular CA), and even odorless variety for foam.

Krazy Glue, the stuff that comes to mind when you think of super glue, is a medium thin material made for most applications that are not foam or rubbers.

it runs like a monster with out the pipe on it , i figured it would run a min and then die with out the pipe on it . will it hurt it to just run it like that with maybe a stright pipe on it . i got it used off ebay and it runs good i just feel if it runs like that with out a pipe on it would it be that maybe it has the wroung pipe on it ? i run it with out the pipe for half a tank of fuel . i run the 30% type and its a traxxas .15 motor . nitro rustler

Xpress

04-02-2011, 05:40 PM

Run the pipe on it!!! You're going to bake that motor without it. I have actually had a customer come to me before that said he had ran it without the pipe, but was wondering why it seized up. They run really lean without the pipes on them, so it's best to run it with the pipe. Also, it vents the exhaust fumes out and away from the components inside (the exhaust and oils can sometimes rust the nuts and bolts for some reason), not to mention it gives you the powerband.

If it's running like crap with the pipe on, I'd think it has the wrong pipe on it. The Rustler used to be a very popular car when it came out, so there should be loads of parts for it.

Also, 20% is what you should be running with that motor, unless you run a hotter plug :)

Big Sal

04-02-2011, 11:39 PM

If it has the stock Traxxas pipe on it...take the pipe off and unbolt it so it comes apart...inside should be a cone shaped baffle....they sometimes melt down...anyway take it out and put the pipe back together....it will run better...but NEVER run without a pipe...

thanks for the info and for saveing my motor . i am for sure going to check out the pipe now to see if its messed up . i been running the red glow plug in it from ebay says its a hot plug .

SonicTronics

04-05-2011, 06:01 PM

Really no reason to run a hot plug in there with that motor. If it runs better without the pipe check your fuel settings on the carb. TThe motor will basically just lean out without the pipe in part because the pipe has that nipple on it going to the tank to force the fuel through, pressurizes it somewhat. I would try running a standard plug first, then play with the needles a bit. Always adjust the high speed needle first. Do some full throttle passes and see what you get. Also clean your air filter before you start tuning as well. The .15s are solid motors, not great performers compared to the newer stuff, but they are pretty stout. Yoyu may also need to add a head shim for running the 30 percent.

Xpress

04-05-2011, 06:14 PM

^That's another thing I didn't think about- the exhausts on these nitro engines are what pressurizes the fuel tank to send fuel to the engine, much the same as a fuel pump. Without them your engine will run very rough due to lack of sufficient fuel supply.

It is the Redcat rampgae TT. Engine and tranny are in the center so it stays extremly well balanced in the air and on the ground. It is also 4 wheel drive. I have the original body but i butched it up pianting it. What i have on there now is a CEN 5-T truck body that has zero ride time on it.

Its a BAJA 5B. Desert truck.

5B is the Buggy pictured below by eXpress.
5T is the desert truck. It is however not an HPI at all, which was basically what I was getting at.

You might be thinking of the Baja 5B, which is the buggy version.

Nope, I was thinking of the 5T.

Macs, thanks for clearing that up.

i have 4 cars.
my basher is a super moded bandit with extended swing arms, extended chassis, CC mamba pro ESC and a 3t motor, liporacing packs 7.4v for bashing and 11.1v for racing, proline caliber tires, futaba s3003 servo and a drilled out chassis to lighten it.

my fastest is a vintage 1/10 TRC disruptor pan car with CC mamba pro ESC and a 3t motor with a 11.1 pack, direct drive from the motor to the axle. it flys when it actually gets traction and not spinning the tires.
