    XTM X-cellerator New engines that fit or rebuild?

    I've had this XTM Xcellerator for most of my life but its been sitting for like 10 years. I want to get it running but its not exactly a show piece so I'm open to options. The original xtm .18 I hear is the same as the sh .18 but even then parts are mostly discontinued so rebuilding is starting...

    Team Associated (Can’t figure out what Model)

    I had the rc car given to me me about 10 -12 years ago. I used it and put it up after like 2 weeks. I found it again and want to get it running. I just don’t know the name or model of the actual car. The the motor says 15 so I looked it up and it’s the size, right? So can I put any 15 motor or...

    Need help/advice with Jato that won't idle well.

    Hi all, My Traxxas Jato has given me a bit of trouble since I got it. I have been running nitro for about a year and this is the only one that gives me trouble. The issue: When the Jato gets warmed up it will do one of two things eventually: 1. It will stall when letting off the throttle after...

    Has anyone used the Klinik air filter yet?

    I was searching the forums and found someone talking about the Klinik Rc air filter and how they were supposed to be better than the others. I need a new air filter for an engine and figured I should ask around about before potentially purchasing one. Heres what they look like if anyone's...

    "Frankenstein Rustler" 2 speed tranny.

    Hey Nitro R.C. lovers! Today I bring you guys the "Frankenstein Rustler" which was made out of 2 used cars (Rustler and Jato) and a few new parts.. I wanted it to look different than the regular Rustler (grey upper chassis) and since the Jato's tranny is black I decided to black out as much as...

    Want to give my revo more power… but how?

    I’ve tried big block but that ended up destroying other components so i figured modding the existing 3.3 engine, I’m forced to run on 16% fuel since anything higher requires license to purchase (which i ofc don’t have) Many have told about swapping to an os 11k carb, but are there any other...

    traxxas 2.5, 2.5R and 3.3 horsepower?

    how much horsepower do these engines make? And what are the differences between 2.5 and 2.5R, some online articles say that the only difference is the blue cooling head but traxxas states that 2.5R makes 0.5 horse power more than the original 2.5, how come?

    I dont get it... (about nitro tuning, everyone is welcome! i need to know more!)

    Q1: What does LSN do, does it effects low rpm or low throttle? if i blip the gas ones (from zero to wide-open quickly, then immediately releasing the trigger) is it HSN or LSN? Q2: does HSN affects idle? Q3: the relation between LSN and idle crew, i can affect idle by either leaning the LSN or...

    Your opinion on Traxxas trx 3.3 engine and traxxas Top fuel

    what's your opinion on the traxxas 3.3 engine? power wise? reliability wise? connecting rod failure? What fuel suits the best? And why didn't Traxxas develop a big block instead? what's your opinion on the traxxas top fuel? really the best fuel as Traxxas advertised? why so high oil content...

    1980s GV tornado and magnum .21 running video

    Its runs! I hate the lsn (like the ones in the planes ) but it runs nice. I can't get it full throttle as it looks like it isnt engaging the spur fast enough/at all. Very happy my little "project" if it could even be called that. I also used the futaba magnum junior that came with it

    Weird that this engine doesn't have rings on it?

    Its a magnum .21 that was bought before the 90s it was made by thunder tiger. Just thought i'd be fun to show off some old engine parts

    Dynamite Big Red pull start after-market replacement

    The one that comes with it is terrible to say the least. I like the engine but that pull start design is atrocious. I break this pull start so quickly because a metal piece connects to the OWB hex. The metal piece strips the plastic pull start. This is the engine in case anyone's wondering...

    Is anyone always worried that you're running lean all the time?

    Even though they have all the signs that its just right ( or slightly rich ). I need reassurance that I'm not the only one who thinks of this constantly
