    Accidentally Stripped (2) Screws Inside Crankshaft

    Hello, My name is Kevin and I am new to Nitro RC 1/8 Scale Buggy racing. I have a Mugen-Seiki MBX8-R with an OS Samurai R03 Engine (see Photo 1) Last night I was replacing the clutch bearings and was in the process of reassembling. I accidentally used Loctite (forgot not supposed to on this...

    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?
  3. :D lmao

    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

    Big red OWB Shot?

    At least I believe so. The pull start doesn't catch and I've already cleaned it plus looks like this

    My first nitro rc just doesn't want to start. Any sort of help is needed...!

    I just got my first nitro rc 3 days ago (it's a HSP nitro rc monster truck 1:10 second hand) (with a SH 18 engine) and it basically looks new and is visually in great condition. Tho i haven't been able to start it yet (according to the previous owner he last started it in December and it should...

    Revo 2.5 big block upgrade(Engine suggestions?)

    I've never really bought a new nitro rc engine, but I would like to upgrade my Revo 2.5 that is on a 3.3 chassis to a big block as the extra power just sounds nice. I know I will need a conversion kit, but what I'm not sure about is the engine I want to choose. Every thread I've found off google...

    Newbie Needing Help

    Hey All, So I'm working on my nitro I got for X-Mas, don't know what brand it was but the engine is a VX-18. It was running pretty decently for a while, then I had a kind of rough crash, it was bad enough to snap a wheel stub axle and I *think* it broke the clutch shoe spring. (the damage to...

    Nitro Fuel for KE21SP engine?

    So, i just got my Kyosho inferno neo 3.0 and the closest shop with fuel only has the Nitrolux Energi 2 Off road, 16% by weight and 12% volume percent. ( https://modelixracing.com/en/18393-nitrolux-energy2-off-road-16-by-weight-eu-no-licence-1-l.html ). I've watched videos and done som reading...

    Needs help with my nitro engine!

    I've recently done a bb swap on my Revo 3.3. But i found the new engine extremely hard to tune. it can't hit the second gear without running lean and bog down, the engine won't idle, runs very unstable. And the power was way worst than my previous engine all though being a big block with 4...

    Nitro engine hard to prime (May be different from what you think)

    I can't prime my engine by blocking the exhaust. But I did it with no problem when blowing through the exhaust outlet or the back pressure tube. When i crank the engine over one time (with the exhaust blocked trying to prime it) i can see the fuel in the line moving forward (by forward i mean 1...

    Thoughts on the OS max30 VG?

    Hey all, I was wondering how good is the 30 vg? I know they have all the bottom and but not as much top end, which is fine I'm gonna throw it into a Savage ss. I'm seeing lots of mixed reviews, and my mate has one that he absolutely loves. So how good are they? I've heard they lose compression...

    why is my engine running so hot?

    I'm running a stock revo 3.3 with optimix 16% fuel I'm running my engine relatively rich and a whole bunch of blue smoke is visible during the acceleration, so i assume that everything should be theoretically fine apart from the fact that the temp was at 280f, i tried richening the needles but...
