Hi guys A couple of days ago I took my RS4 18SS out for a bash and everything was going well untill it started to lose the will to move forward. So when I got it home I took the wheels off, readying myself to pull apart the drive train and one of them had stripped the plastic hex and the hex...

So if I'm going to get anitro car, i want it for drifting. i was going to get the 4-tec, but i found this thats made for drifting, is HPI a good name, and is this motor any good? http://www.hpiracing.com/kitinfo/10071/

I need a set of cheap motor mounts for this RS4 3 EVO I'm trying to get running. They are basically just standoffs so the motor sits level in the chassis. Anyone have a set cheap? LHS has em for $25, but I'm not spending that much on a car I probably will drive once and sell or trade. lol

what would be a better choice and why for my new rc. Details about my driving: i will be racing and jumping mainly, and probably some speed runs now and then. i am also not one of those people who likes tuning the car or working on it (But i will if i have to). #1: HPI firestorm #2: HPI...

Hi guys and gals, I've got a HPI rs4 evo 3 18SS and I think I'm having a problem with the exhaust gaskets, with the paper-ish they gave me they only last about 3 tanks of fuel before they disappear, is this meant to happen? I scavenged a rubber gasket off an old engine that is the right...

Just a quick question. I just purchased a OS MAX 15cv motor and wanted to know what was needed for the install on a HPI rs4 2. I've just been rebuilding the hpi15fe for the past 7-8 years and thought it would be nice to have a different motor for once. i have the basic engine mounts from HPI...

Hello Friends, Finally I got my RC car started, I tell you it was fun just hearing the sound and playing around, I am done with the break in and probably would need to do the engine tuning. I had few doubts. TH.TRIM, if this is kept on minimum my HPI RS4 evo+ doesn’t start, I have to...

Hey all I'm new to these forums and new to nitro RC too. I purchased myself a HPI RS4 3 Evo + the other day, got it going all sweet while breaking in the engine, but not long after that the glow plug died. No big issue tho just replaced the glow plug and it was running again. Not long...

I have had my rs4 for a few weeks now. I have run prob. close to a gallon of fuel through it and everytime i run it it doesn't sound like it is shifting into second. The thing is fast. I can out run my friends CEN .15 all day long, but i don't hear mine shift into second. Anyone have any insight...

Hi All. I am new to the RC scene and have just bought mysellf the HPi RS4. Its a great car but I'm sitting with one problem. I had to replace the 47t spur gear, but since replacing it,the gearbox is a little bit noisy. It sounds like a grinding noise. I've checked the gears but can't see...

I basically built an RS4 3 18ss from an Ebay purchase but I am running a Picco XP .15 and a 68 Camaro Body. I am currently using a 19/45 1st gear and 23/41 2nd gear combo. Using my new GPS for the first time the best I could get out of it was 48.3mph using 20% nitro. The only tuning I did was...

Hi everyone, So I decided to start another project. My first rc car was a HPI rs4 mini nitro and I still have it but needs a new motor and a 2 speed. I wanted to get it running again and was wondering if anyone has left over parts or even a whole car. I been looking everywhere for the last 2...
