    I’m running a stock 3.3 engine, and I’m switching to 16% fuel, question is, should I use a different plug to adapt to the new fuel I will be using? (Currently running stock plug and worked perfectly on 20%) thx

    Disclaimer! I'm not saying or claiming to be an expert I want to see if I'm right about the things that I've been studying about within the last 2 months.

    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.

    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.

    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.

    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...
