The Need for Speed: ARRMA INFRACTION 3s and the Race to 100mph

[@jbrc1322]

I would trim that spoiler down. At those speeds, having all that downforce on the rear is only going to lift the front and reduce steering and contribute to backflips.

[@RC4us]

I have almost all of it trimmed away I did think about running it once without it all together to see what happens I’ve never done speed runs until now

[@KBASHRC]

83-85mph is when rear squats from downforce..the second rear gos lower than front it blowsover..best option to progress is to replace shocks for turnbuckles. Then you can adjust your ride height to perfection an rear will never squat lower than front...

[@RC4us]

I thought about that but really I don’t think that was the issue I’ve had it well into the 90s with out the issue I think the missing front splitter an the 30-40 mph wind gust didn’t help as soon as I cleared the building that was blocking most of it is when it would happen…. I’m giving it one more shot soon an then I’m calling it my fastest was 96 an it didn’t actually turn around an come back 94mph is that top speed

[@phillybrc]

Maybe try running the oppesite direction. The wind was definitely present

[@RC4us]

Yeah I did actually try it a bit off camera it was just a really bad day but I’d had it planned an batteries were already charged so I went for it luckily I didn’t really damage anything

[@t.d.j.dejong6285]

Great run. Stock motor and ESC??

[@RC4us]

So it's the stock 3900kv motor with a 6s firma 150amp esc

[@CarstenKoppenhagen]

Gab es Probleme mit dem original esc

[@jamesdalby-r3v]

This may sound like a dumb question but why is the battery connectors plugged in with only 1 pin of the ec5 like that? Not trying to take the piss but genuinely curious that’s all.

[@RC4us]

@@jamesdalby-r3v never a dumb question but I'm not real sure what your meaning

[@jamesdalby-r3v]

Hi thanks for the reply! I was just meaning look how the battery is connected to the esc in the car. Is this just for transport or something so the leads don’t flop around?

[@RC4us]

@@jamesdalby-r3v all ok at the beginning yes it's just to hold everything in spot.... also allows me to have my lipos strapped in and I know where my wires sit when I'm ready to go I just need to plug them in battery is already strapped in

[@jamesdalby-r3v]

Nice, i wouldn’t have thought to do that but i just might start doing it myself. I have this same infraction and also the same battery you have in there at the beginning of the vid! Love the car! But just not having to buy new tyres all the time as they are pricy here in Australia 🤣 Appreciate you taking the time to reply to my comments 🍻

@ no problem buddy

[@blacksheeprc8113]

Nice try brother. I had the same problem mine shooting up in the air like at about 111 mi an hour and it was just me trying to pull the trigger too hard every time I rolled into it. Easier 140 some mile an hour. Just an idea man. I know I know he's rolling into it easy but that was a problem I was having and I also had to put fuel tubing in my rear shocks to stop the squat cuz when you're laying in the trigger harder it's making your rear end squat. Your earring goes lower than the front end. It's going to do that every time. Not saying you don't already have it set up that way. Just giving my advice

Sind im Fahrzeug Plastik Diffs verbaut?

[@RC4us]

@@CarstenKoppenhagen no 4s metal ring gear did

[@CarstenKoppenhagen]

Ich überlege mit einen zu kaufen, gibt es Motor oder Hitzeprobleme?

[@CarstenKoppenhagen]

Bist du noch zufrieden mit dem Infraction?

[@RC4us]

@@CarstenKoppenhagen no in fact i use the stock 3900kv on 4s and went 100mph using a 6s esc

[@cacanjacowans540]

Bump stops & shock limiters

[@RC4us]

Yes I’ve installed some limiters inside the shocks to help keep it lower to the ground
