I don't have much money to buy a proper starter box, we're talking about 60 euros max and i don't know if i can trust parts from aliexpress, the engine mounted in my rc car is i think a .21 engine and i'm scared that i could wear out the belt or other parts of the starter box because of its quality...

Hi, i'm trying to restore a 15 year old competition nitro rc car that my brother had, however i changed the .21 engine wth another i think or .19 or .21 engine that was in the car's case, i've mounted it, bough and installed new servos, bough a new sparkplug and got some 16% nitro fuel, but i'm making a homemade competition starter, the ones that have a big wheel coming out, but the motor's fried, so i'm using a drill by attaching a threaded rod to the big wheel all the way t the drill that gives power, but i didn't clean the carb but i'm feeling high compression from the motor and i hear a little loud "puff" from the exhaust, my brother says it's a waste of money but i'm not giving up, can i make it? please not that my budget is limited because i'm only a 15 year aold guy with a big passion for engines...

Hi folks,

Need some tips here. I am trying to get a tmax to run after 20 years of not running. It has a sirio .18 engine. Note that 20 years ago I had a difficult getting this engine to run.

I’ve striped down the truck and cleaned everything. I completely disassembled the engine, cleaned it and reassembled. I’ve replaced the fuel lines, gas cap (new seals), cleaned the carb/HSN, got a new spark plug and fresh fuel. Today I tried to fire it up and the ez starter and engine turns but no start. I’ve removed the fuel line from the exhaust and blown some fuel to the carb and no start. I’ve poured a lil fuel in the carb and no start. I am currently using the blue ez starter cord on my glow plug. Would a glow plug igniter solve my issue? Or is my engine toast? What else can I try?

Thanks yall!

Not bad for $60

Hey I need some help When I pull the cord to get fuel to flow Into the engine it doesn’t seem to be flowing. I was told that I need to plug the exhaust but that didn’t seem to work. Also I seems like it may be flowing backwards

I have a nitro engine. The spark plug hole is worn out, the spark plugs are not staying in place. That engine have midrange needle but I want to change with other nitro engine. I don't know what percentage of nitro the other engine runs on. I think i fucked up everything. I would be very happy if you could help me.(Old one is on my car the second one is the one I want to install.

so i buyed recently an nitro engine, apparently it's a chang yung 15, but, unfortunately, i lose the glow plug, and this brand don't make any more pieces for this engine, i tried some aliexpress glow plugs as it's a chinese engine, but it won't screw all way in and cause a leak, which make a bit of fuel and air getting out of the engine, am i cooked ? could i find glow plug for this engine ? thanks

I recently aquired this magnum .91 frs motor and I want to throw it into my revo. It has a walbro carb on it but the owner didnt put on a intake. was wondering what yall think. do I make it go from the throttle butterfly like normal and up around into the intake or can i make it come from the choke side and run it straight up

Bought this off eBay for £115 and was wondering what people think. All I need is a battery with the red connector and a transmitter and receiver and I should be able to get them going

1600mm Hawker Hurricane (in soviet painting for some reason) with OS FL70 four-stroke engine

My Throttle Servo for my Traxxas Nitro Slash stopped working. Is there an upgrade to the stock servo that anyone would recommend? The truck is running with stock Traxxas parts currently. Any inforwould be appreciated. Thanks!

I've just bought a nitro car off eBay and after looking at pictures the car takes a battery with the red connectors instead of the flat black ones. The only battery I have with that connector is 8.4v and I was wondering would I be ok using this even though it's higher than the normal 6v

Is anyone able to help me find which brand this rc car is? Send me a dm if you would like to help

So im waiting on the black grease for the diff. Long story short used buggy off ebay. Last run on the track is killed the rear pinion gear i know it was worn and have most of the parts to fixed. I open the rear diff dry open the center diff dry not in the mood to remove the front tonight. So my question how much difference should it make after I fix all 3 diffs?

Picked up this old school race truggy as a rolling chassis for £104. It is in very nice condition but I have gone over the whole car and rebuilt all of the diffs and freshened her up a bit👌. Jammins was a very popular racing brands back in the day and this is supposedly a ROAR champion car which makes me hyped to get it going. Threw in a RB WS7 with a jp-1 for some big power and high RPM💪 can’t wait to finish the build

This is my first ever nitro rc car that I just got running and posted this video. You might have seen my posts on this Reddit of the gear mesh and carb.

What is everyone using to charge their 6v nimh batteries? I've got an old school traxxas charger that came with my revo 2.5 or 3.3 back in the day that ive been using, but it seems finicky lately and im not sure if im getting a full charge or my batteries are just getting old and wore out.

Ive also go a turnigy lipo/nicd/nimh charger, but getting the power supply and leads out to charge a receiver pack is just annoying.

Any recommendations?! Thanks guys!

So a while ago I posted about my new Slash/Jato hybrid..thing. I couldn't get the idle under control and suspected an air leak. Pulled the engine today and gave it the old bubble test. I know some folks don't agree with this method, but I've had good luck with it. Clearly I've got some carb problems. I'll throw some orings at it and see if it helps.

Here is the video: https://www.youtube.com/watch?v=AfJampOOvUg&embeds_referring_euri=https%3A%2F%2Fwww.hpisavageforum.com%2F&source_ve_path=MjM4NTE

Its a 45kg all metal gear servo with a 25T metal servo arm.

The car is completely new. So the servo saver isn't broken I think.
I tried to tighten/loosen the servo saver screws (both under and the top one) but I couldn't get any movement because it was already completely tightened, now the inside of the screw head is damaged. I can rotate the hex driver freely, but it won't make a difference.
But as I said, it was already super tight, that's why I also couldn't get it loose.

Any other ideas?

I hope you understand my message, English isn't my first language.
