    Fuel won't flow and can't prime NITRO BUGGY HELP

    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...

    JP Eagle R9s old nitro engine - value?

    Hello I have come across this JP Eagle R9.s engine and am wondering what a price would be. I can't find much info online other than threads made pre 2009. I think I am going to sell it with the whole car, which I also don't know what it is. I assume serpent vector. Thanks for your time.

    Hobao Hyper 7 .21 or .28?

    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...

    Kyosho FW06 Audi R8 2019

    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...

    Kyosho gxr28 exhaust manifold options?

    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...

    My VX 18 engine keeps shutting off

    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...

    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.

    Engine options, not many.

    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...
