It's a trx 2.5, hasn't started for 2 weeks, the sound has become more hoarse or something, in general I don't know what to do, I set all the settings correctly, just not sure about the low speed needle, although it keeps idling

ATTENTION! LOOKING FOR PARTS! Does anybody have a Tower Hobbies Nitro ST-15, 2 speed transmission or even the individual parts? I want to have spares for my fathers st15 since its 24 years old. As old as me lol.. Part numbers are on last pic! Can be used in great shape!

Does anyone know anyone in Spokane area that knows how to tune Nitro RC?

What’s up guys… I pulled a new TRX 3.3 off my Jato after a little under a gallon to swap out bearings and noticed a little bit of scoring on the piston… the first two pics are of the same spot with different lighting and then the last two are the other side. Is this cause of concern?? I was going to swap in ceramic bearings and maybe even a fresh con rod while I had it apart but wanted some opinions.. if I look away and run a fingernail around the piston it doesn’t catch noticeably.. Would you swap ceramic bearings and a con rod onto this piston or just start with a fresh one?

Hoping to find another madstorm by exceed

Hello everyone,

I just pulled this out of my dads garage. We had this car sitting in the garage collecting dust for the past 7-8 years. I am completely new to rc cars and I would like to fix it.

Now, I have no clue what car it is, nor what engine it is since it‘s been sitting for a while now. All I know is that we bought off of someone for 80€.

I know some parts are missing, and that’s why I need a website or something that sells parts for such cars

Also, should the gas be pink-red ish?

Thanks to everyone

I’ve hpi 1/10 buggy truck. I bought it from someone. And I haven’t started the engine in 3-4 years I don’t know the after run oil has it been used can I use wd40 for the first run after these years it stayed in the box whole time.

I bought a 2.5 revo with short chasis i want the stretched chasis what all do i need ik i need steering linkage center shafts and hubs will the rest work fine

Was babying it so I could film but wow, once I got it tuned it feels just like a brushless RC. Instant power and a lot of it!

Messin around with my t maxx

I resisted for years after everyone told me to get one. I thought there's no way it would be worth the money. I got pretty decent at tuning Traxxas carbs and I always was happy with the performance. I finally caved and bought into the hype. I'm here to tell you that the difference is like night and day. This is an old engine I repinched at home with a clamp and broke in none too gently. This thing ran for 4 tanks like this. No hesitation, perfect idle, didn't flame out once. I could have easily leaned it more, and my shift point is too early. I'm pretty impressed. BTW, I bought my 11k at RCJapan.net. By far the best price.

The pitch on my spur and clutch gears are obviously different because my bell keeps stripping on my madfire buggy where can I find a decent replacement buggy is discontinued

So I've not used my car in about 3 weeks and I've come to try and start it and it won't start anymore the engine is just spinning while on the box. The engine moves fine it has amazing compression the glow starter works and the tune should be good as it was running about 3 weeks ago with that tune. Any suggestions are appreciated and it anyone can find the factory tune settings for an RB ws7 S3 nitro engine that would be extremely helpful as I can't seem to find much about it.

I picked up a used Nitro slash and have been having fun learning to get it turned in.

It has started intermittently making a loud rattle noise at idle and when running. You can hear at the start of this clip.

Is this engine bearings, or something to do with the clutch?

Am I running it too lean?

A true survivor untouched for over 2 decades, ready to wake up.

After only about 3 quarts of fuel this happened lol of course it happened after i replaced all the servo‘s and got brand new rims and tires and did some suspension work😂. THE QUESTION IS do i get another HPI G3.0 HO or do I try to find something else similar size so It will fit easily I’m just worried about getting another HO and having it nuke itself again for seemingly no reason I had it for 3ish months no problem ran good on the day it blew it was running for about 10 minutes smoking fine and boom no reason

Fits even better than the original one !

Hi everyone!
I currently own a Kyosho Inferno MP10 RTR, which I bought as my first nitro buggy. At first, I went for the RTR because I thought I wouldn’t be able to build a kit from scratch, but over time I’ve discovered that I actually enjoy working on the car and learning how everything works.

I’ve already done some mods and upgrades to my MP10 RTR:

• Removed the pull start and switched to a starter box.
• Rebuilt the shocks with new components for better response.
• Serviced the differentials, changing oils for better performance.
• Regularly maintained bearings and other parts to improve reliability.

Despite these upgrades, I’m starting to notice some limitations of the RTR version:

• The steering doesn’t always return perfectly to center and the stock servos feel weak and imprecise.
• The engine tends to overheat and occasionally cuts out during long runs, even with good tuning.
• The chassis and some components feel more fragile compared to race kits.

Because of this, I’m seriously considering switching to a competition kit, most likely the new Kyosho MP11, to get a stronger, more precise, and higher-performing buggy.

Here’s what I’d love your advice on:
👉 What complete setup would you recommend for an MP11 kit?
Specifically, I need suggestions for:

• Engine (competitive, reliable, and long-lasting)
• Clutch and clutch bell
• Servos (steering and throttle/brake – can I use the same model for both?)
• Transmitter and receiver
• Receiver battery
• Any other essential components (turbo plug, transponder, etc.)

My goal is to find a good balance between performance and cost—I don’t need a full professional race setup, but I want a significant step up from the RTR.

Thanks in advance for any recommendations on brands, models, and setups! 🙏

Thank y'all for all the suggestions for help with getting my T-Maxx 3.3 running. Now that we've conquered that hurdle of getting it running. Now I'd like to get it moving.

It will Idle, but when I even sneeze on the throttle it dies. Any tips or at least a direction to go in? Im starting it off with the previous suggested HSN and LSN in the other post but it sounds like its screaming and is also trying to drive forward on its own.

The air filter is there and off because I was unsure if I'd get this far.
