nitro engine

I just got a pre owned nitro jato a few weeks back and the engine attached was a TRX 3.3 and the previous owner had broken the piston rod, he made sure I was aware and gave me a Discontinued OS Max 18 cvr nitro engine that has never been ran with it. How do I piece this thing together and should...

Hi I'm really struggling with getting my hyper 7. 28 running nice so I can take it for a rip up. I brought the car off Facebook from a guy who seems genuine told me about the car and wat he used to do with it ( ex racetuned engine) so the engine is race tuned and set up for racing so as sokn as...

Hello, so I recently just got a Tmaxx 2.5r, is what I was told it is, and it needed a new pull starter, he gave me one(shape for the crank is like a circle with two flat sides) but it doesn’t spin the crank, then I noticed that the shape for the crank on the motor is a hexagon nut. Any help at...

So I have an HSP 1/10 scale warhead buggy and I haven't used it for about 5 months. I tried to get it going but I couldn't prime the buggy to get fuel into the carb. The only way I could move the fuel to the carb is by blowing into the tube that is connected to the exhaust. When I do this I am...

I have a ofna nitro engine that has a 3.5 on the side of the motor and I don't remember if it's a .26 or a .28 I'm also trying to find a 3 or a 4 clutch setup that has the flywheel too. Thanks

just wondering what everyone prefers for a clutch setup? 3 shoe, 2 shoe, aluminum,composite,and which brand seems to last the longest. Thanks.

Hi All, I am looking at buying myself a Hobao Hyper 7 as fed up with my Acme Condor Pro (Probably no surprise to some of you considering I feel like I'm polishing a turd everytime I fix it). I have heard mixed reviews about the Mac star .28 engine for the Hyper 7 and most people prefer to go...

Wassup I'm Ray. My picco .26max is in need of O rings for the low speed needle. Does anybody know where i can purchase?

Just bought this car. Still breaking it in and tuning it. I still want to tune it a bit more before I take it out onto a tar track. I replaced the rubber tires and went with slicks and it handles very well on the street. It does lower it more than stock tires by about a 1mm. It sits 5mm stock...

So I scooped up a Kyosho gxr28 nitro engine for a back up swap big block. The exhaust manifold it came with is a left hand side(driver-side in US) - looking from back of engine I would prefer it to be on the right side. The exhaust flange is a flange bolted to the engine, so it doesn’t use a...

I tried starting my vx 18 engine on my nitro car and it would start but only run for a minute then shutoff. Then it would take 5 to ten minutes for it to start and do the same thing. So i thought it was gummed up inside so i brought it in my garage and took the motor apart and cleaned it out...

So i recently perchased the losi 8ight t rtr truggy, and have finished the break in procedure. I started tuning it and have almost gotten it perfect, the only problem is when I pull the trigger to accelerate there is a lot of lag and what sounds like the engine bogging down. I do live in...

Hello All - New to this forum and a beginner with NITRO RC cars - Do any of you know the backing plate I should buy for a Redcat Lightning and Exceed Short Course truck with a Vertex .18 engine? I recently bought an off brand electric starter kit and the instructions mention that the backing...

Now that I finally know how to take my Nitro cars apart, I will be attempting to seal two engines tonight

The dynamite .21 engine that comes stock in the losi 8ight with sidewinder 20% nitro....is an OS#8 plug ok or should I go with the colder R5 plug? Oh I live in south west Florida, usually running in 90* weatger with 80% humidity

hey, I'm working on the slowest project ever, recreating my old Picco powered Revo Platinum and I can't for the life of me remember what I used for throttle setup. can anybody point me in right direction? got the ofna mount and Picco .26 max. Thanks in advance

Hi guys, Still new to the hobby learning lots from here. Have a dilema. Started the TenT, after it sitting for couple of month. Trying to tune it. The mix seems a little rich even when LS needle is fully closed. Can someone clarify what could cause this. Thanks,

As the title asks, which I’m hoping isn’t a dumb question. Do nitro engines come sealed? Or is that something the user does? I get a lot of nitro leaking from near the carb when I run it hard.

Unfortunately not too thrilled with my HPI Bullet. It does run well and starts up pretty quick, but the engine doesn’t have the power for off-road I’m looking for. It’s also a pita to get a decent tune, unlike my Losi 8ight, which was a breeze to get a nice tune on. Anyway I was looking around...

My nitro rc car starts and then stalls shortly after every time even if I give it gas . It like it bogs out. We've tried leaning richining new glow plug fresh fuel. Please help I'm really frustrated. I even took the backplate of.
