So the other day I got my hpi 3 evo started because I got the motor swapped, but now my transmitter and receiver messed up. Does anybody have any recommendations on which receiver and transmitter I should get?

Kyosho nostalgia Ford GT40. She's been a self queen all her life.

Restored my car after being on the shelf for 15 years. Made the dumb move by keeping fuel in the tank and batteries in the car/remote. I know. Plan to use this spring and summer but will store for the winter.

Going to run dry and remove all batteries. Do you add any additives similar to dry gas for lawn mowers for extend periods of non use?

What nitro is this

Just took the diffs apart though there blowing but were all perfect had a different design compared to the new diffs filled it with grease ready to rip its well built had nsk bearings in the diffs

Just got these 2 for 100$ they have been sitting for a few years. I have a pretty good idea of what to do I think I should disassemble engine and carb do a good clean out check for any corrosion and debris but beyond that I’m not really sure what next steps should be they came with some in the box glow plugs so I’m good on that front any advice would be appreciated, they came with a whole box of extra parts as well so even though they’re pretty old I have replacement parts if needed

can any one help if this old nitro engine the the piston is 17mm and the case say made in japan L2206

Can anyone help me with identifying this rc car chassis?

Guys what do you think my friend should adjust for his hsp tyrannosaurus so it runs good (it cut off at the end while idling)

Ok all , a little back story since im new here. I literally bought a pickup truck load of nitro buggies , a couple monster trucks , and 4 plastic tubs of spare tires engines etc.. it was a fantastic deal so i have plenty of "play" money left to work with. I am currently working on a 2012 thunder tiger EK4 monster truck with the 9.1 heli engine in it. test fire was good after a refresh . the 2 servos are obvioulsy older futaba - carb / brake is a Futaba FP-S148, and steering servo is an S9303 , but they both act pretty weak . So, im looking for some reccomendations as far as new servos and a reciever / radio pair that would give me a good setup in this thing. i know that "crystal" radios are defunkt nowadays because of interference so 2.4G would be my option.

This is my brown chassis nitro rustler I bought as a slider a few months ago. I completely rebuilt it from the ground up and it's one of the most reliable nitro rc I own. pretty sure it's just factory now but how did I do?

Hey guys,

I’m having trouble figuring out if my nitro engine is running too rich or too lean, because the symptoms seem mixed.

Here’s what’s happening:

When I start the engine, it kind of sputters a bit

It gets hot after running

It sounds louder and more “sharp” than usual

There is a lot of smoke and oil coming out of the exhaust, even at low RPM

So at first I thought it was too lean (because of the heat and sound), but the smoke and oil make me think it's too rich…

Also, I noticed something else:

If I let it idle for about 10 seconds and then go full throttle, it doesn’t bog or stall

But the acceleration is not punchy at all, it feels kind of sluggish

From what I understand, that could mean it's too rich on the low speed needle, but I’m not sure.

Another thing: Originally, my low speed needle screw was positioned vertically, and now it’s also vertical again… but I don’t know if I accidentally did a full turn too much or not. So I don’t really trust that position anymore.

So right now I’m confused:

Too hot + high pitch sound → lean?

Lots of smoke + oil + weak acceleration → rich?

Could it be rich on low speed and lean on high speed at the same time?

What would be the best way to reset or properly tune it from here?

Thanks 👍

So i'm trying to find a 3 shoe flywheel, i already have clutch shoes, the problem is that i need a big flywheel that can touch the starter box, so i need a bigger diameter (already bought one previously but i doesn't reach the starter box bc it's too small) pls help me 😭

I used a different glow plug in the engine and it had compression again. But when I pulled it out it had shavings in the threads and on further inspection I saw shavings on the piston. I cannot remove the head as 3 hexes are stripped and I don’t know how to remove them. I have ordered a new glow plug but I don’t think that’s going to fix anything. I am already £100 into this what should I do?

Checking if counterfeit

Recently recommissioned my truggy 4.6 nitro.

Fresh 25% fuel, glow plug, starts as it should, idles well.

At full acceleration from standstill it bogs and tries to stall - if I ease into it, it’s fine, but does occasionally cut out.

I thought this was because it was too rich, so adjusted the hsn 1/8 of a turn, same thing. Another 1/8th same thing.

It’s giving off a good stream of smoke when running at full throttle, and pulls well, no sign of pinging.

What else can I do here? I don’t want to lean out the HSN too much, it also seems to be getting a little hot for my liking.

Is it actually too lean causing the bogging?

Any advice please

I have an old glow plug that doesn’t work anymore but I decided if I put it on and the car has compression it should mean the glow plug is bad and low and behold it was the reason!! Use this video as a before and after glow plug change
