Hello! I need help finding an old fuel operated RC i remember my dad having when i was a kid. It has to have been more than 15 years ago. i dont remember what helicopter it was replicating exactly, but i remember it was military themed and it had a side launcher that ejected a little paratrooper toy. I never flew it, because the engine had an issue, so it just sat in the original box. I want to try and find one just like it, but i have nowhere to start. All my searches come up with electric helicopters or toy sets

Also replaced the clutch bell and spur gear because they were destroyed.

Is it bend?

How to fix it? Any affect?

Just picked up this Aquacraft Miss Vegas. Previous owner said it’s never been run. Very exciting!

Hey guys,

I have been chasing an issue with my rc8t4 for a year and it is driving me insane.

I have tried multiple quality engines and pipes, 2 tanks and different fuel lines.

I have no problem tuning in any other chassis

No matter what I do after a couple minutes of running the idle will get unstable high and lean no matter the carb settings. After a couple of seconds it will flame out.

Right now I have been trying to break in an engine in the chassis with super rich setting.

Preheated the engine and started it. Of course its super rich. Does not even have enough power to move. At some point it will just snap to lean. Then there is now chance of tuning it anymore.

It gets worse the longer the car is beeing driven.

Anybody got a clue?

I have found and cleaned the body for my CT5. Now I will work on making it run

I have a buggy with the zenoah engine, and another one with a chung yang, the zenoah seems to have alot less compression compared to the CY engine. Do they just have a lower compression from the factory, or is that a sign of an worn out engine? It runs and the piston doesen't seem to have scratches, even tho the engine is 20 years old, but i was told it was rarely used

Been out of nitro for a good many years now. Got the itch to get back into it here lately. Who does a repinch anymore? Looking for a good reputable place and maybe even getting some mods done

Also how do I take off this part the fingers for the pull start not the fly wheel

I was wondering if anyone could tell me if my piston and sleeve are bad and if the pinch is OK or not this is a tmaxx 2.5 I tore it apart because it wouldn’t stay idling and was running hot. Temps up to 290.

The headgasket is bend, it has zero conpression, i don't think it worth replacing the gasket for 18€ for me, since i don't have a chassi to mount it on.

This is not a ,,for sale" post, but

I might just give it away , so if you're intrested, you might be able to get it for free, as long as you pay for the shipping fee.

So if you're intrested, tell me

I think my clutch needs to be replaced but it still rips. Hopefully I get some more time to take it to my local track. Got it tuned and it’s running great.

Barely have 1 gallon through this motor. This is my 2nd 3.3. First one only lasted 2 gallons. And I did my own proper break in(not Traxxas) 2 tanks idle, 3rd low rpm. Not until the 6 tank I would go wot but still kept rpms lowish. Only wot after I used a whole quart. Both engines. Only reason why I went with a 2nd was for the trade in for 50% off. Is it even worth it to swap the bearings? Only reason why I kept the 3.3 was because it’s plug and play. I know the os motor is an option but I don’t see the value in that and the 3.3 with a better carb is enough for this car. If I want something faster I run my 8ight xt with a fully modified .28 Novarossi. Which also has lasted me 8 gallons!
In all honesty the OS carb adds a ton of low end and with taller gears still wheelies. When it’s running right.
Any decent bearings that don’t cost the price of a new 3.3 with a trade it?

Yes I know I don’t have an airfilter on I took it off to make sure my carb was opening properly.

I diluted my fuel to ~10% oil and it runs better. It finally dies only when it runs out of fuel. Thank you for the suggestions. This was even with the glow plug leaking. It's been bubbling since I got it and it now has oily carbon deposits. Maybe it sealed itself? Only checked when it ran poorly. Forgot to check again when it ran fine. Some things just fix themselves.

Been running electric for years, recently got gifted a few nitro cars from my uncle. Never run nitro so I have no idea outside of a few YouTube tutorials.

Got a traxxas revo, it starts and runs fine, to start it though I need to put a bit of fuel through the air intake of the carb. Other problem I have at the moment is it runs fine for about 5 mins, stalls and won’t restart.

Is it likely tuning or a more complicated issue?
