Infraction Top possible speed for 1/8 Arrma Infraction 4x4

[FE3DM3]

I currently have a 1/8 Infraction 4x4 running 4s. My question is, how fast can I push it? I’ve upgraded everything minus the all aluminum parts. 2300kv 3665 brushless motor, 22t Pinion Gear, programmed 120a brushless ESC, dBoots street tires. I haven’t changed anything with the differential. I’ve noticed when I get top speed she gets a little wild. I haven’t put a speedometer on it yet, but from watching it I’d assume it’s probably hitting about 60-70 easily. How fast is everyone getting theirs and what mods have you done to them to keep them on the road? Thanks!!

Welcome to the forum!!

@vwturbowolf has taken a Vendetta (which I believe is the same platform) to 170mph+. I'm sure he can give you some pointers on what to look out for as you increase your speed.

Great to have you aboard!!

As a follow on to the reply above, I direct you to the Speed Runner's subforum where you can see how fast people have gone with the platform: https://www.arrmaforum.com/threads/speed-run-list-personal-bests-of-the-forum-v2.51640/

But first thing you need is a GPS speedometer as you don't want to be guestimating your top speed.

I appreciate the heads up on the speed runner subforum. New here. My next big purchase is the speedometer.

I'll add that you also do not want to throw your cell phone on the car to test speeds

@FE3DM3 it sounds like you want to know how fast you can take the original electronics? I would estimate up around 80mph.
You will have to get more invested with a Castle MMX8s or XLX2 if you want to go above 100mph which is very possible.

I’ve upgraded everything in it now minus the diff. It was the base model stock brushed infraction 4x4 mega. I’m using off brand parts in it for now until I want to really spend money on it in the near future. Just playing around at the moment. All the parts listed in the OP are upgrades I’ve made to it.

@LibertyMKiii not throwing my phone in it. Haha! I’ll be upgrading everything again to branded parts.

Feel free to ask questions prior to spending that hard-earned $$$.
Many aluminum "upgrades" are not worth doing. We can help guide you and save you some money.

You may also want to ask yourself how far down the rabbit hole you think you may end up going.
It may be best to consider a 1/7 scale platform that opens the possibilities and everything is engineered for high power and high speeds.
Like the Limitless V2 for example.

I totally didnt zip-tie my phone to the back of my mojave when it blew over at 70 mph. On a different note all together my phone screen just happens to be cracked.

What app is that? Lol

 

[Valkrieys]

I would spring for the SkyRC gps unit most of us (me included now) use. But here it is if your curious. They go on sale pretty frequently on Rcjuice.
