A pleasant contact and an effective way to each give the wheels a brand new look AND cover the middle wheel nut! The tires, though un-branded, look actually good as nicely and have a shallow sample, including as a lot rubber to the bottom as potential. Their low-profile look additionally helps reduce tire squirm whereas making high-speed passes, one thing the Audi likes to do.

A single strap retains the battery in place with the tray being adjustable for various battery sizes. A multi-piece heart backbone runs the size of the automobile, overlaying the entrance and rear diff enter outdrives in addition to the spur and pinion gear. HPI has additionally taken the additional step to make gear modifications simpler – as an alternative of eradicating the entire higher items, you may entry the gearing via a decrease panel positioned on the underside of the chassis – 6 screws and increase, you’re in.

The decrease arms are good and thick with each droop and shock angle changes. Ball stud changes are additionally obtainable, nevertheless adjustable turnbuckles can be a prompt improve to take full benefit of those tuning choices.

The 1:1 Audi e-tron is a triple-motor, 600kW (815hp) tremendous light-weight race automobile that’s able to a 0-60 time of roughly 2.5 seconds. HPI, wanting to duplicate extra than simply the look, stuffed their highly effective Flux brushless system into their scaled down Audi e-tron. The Flux system is kind of stout, permitting energy from both a 2S or 3S LiPo pack to be delivered to the 4000kV brushless motor. This, with elective gearing, can push this Imaginative and prescient GT to over 70mph – proper out of the field! We expect that is simply achievable seeing as we hit 65mph in inventory type! We are going to, in fact, be seeing simply how briskly we are able to get the Sport 3 to go. In fact.

The park throughout the road from the CompetitionX compound was the positioning of the preliminary testing. Nonetheless, earlier than we get to the good things, let’s get to a fast down-and-dirty overview.

In the course of the first shakedown run, we seen just a few issues that we felt had been going to trigger points as soon as we began performing some full-speed passes. These can be:
1) The rear diffuser (linked to the physique) would cling up on the again of the chassis inflicting it to rub and scrap on the bottom.
2) The chassis saved bottoming out and we couldn’t increase the experience top. We would have liked to examine the shocks to see what was stopping this.
3) The steering was wandering alot, so we would have liked to handle the servo saver to take away this.

All of those, aside from eradicating the limiters within the shocks, had been straightforward fixes. To see what we did to treatment every one, watch the video above and scroll to the 6:36 timestamp.

Now that we obtained that out of the way in which, let’s chat about how the Audi e-tron Imaginative and prescient GT supercar ran after our mods!

The primary preliminary runs with a 2S pack had been enjoyable however, as everyone knows, extra energy means extra velocity means ‘extra funner’. Including the 3S pack actually introduced the Audi alive and, after the modifications to maximise efficiency, the Sport 3 simply dealt with the almost-70mph speeds. Now, if almost-70mph isn’t your factor, you may improve to the Excessive Pace Gear Set, for about $20, which supplies you a 53T spur and 44T pinion. That’s going to be our subsequent improve for positive!

Dealing with
Previous to our mods, we’d need to say the dealing with was a bit on the sketchy aspect. On any form of uneven floor, each the physique and chassis would backside out fairly simply. As soon as modded, you possibly can nonetheless hear it contact down on rougher surfaces nevertheless it didn’t upset the automobile practically as dangerous. As soon as on a smoother floor, although, the Audi was a pleasure to drive – very steady with a very good stability of steering and grip – so long as you drove it inside its limits. If we pushed the automobile (on 3S), it could exhibit some oversteer or understeer however, for probably the most half, it was a steady automobile to drive.

Once more, as soon as we made our mods to the Audi, it was a enjoyable automobile to drive. The suspension works nicely on each easy and tough surfaces (when you choose that chassis up off the bottom), with the oil-filled shocks doing an incredible job of absorbing any irregularities. Now, one draw back is the dearth of changes on account of mounted hyperlinks however, with an improve to turnbuckles, this automobile could possibly be tuned for higher efficiency. That is one thing we’ll be doing sooner or later as nicely.

We don’t actually like to check the sturdiness of vehicles. We determine when you merely drive your automobile usually (and never attempt to soar a home), it ought to final you a very long time. Properly, because of the horrible dealing with earlier than our mods (and our first velocity run AFTER our mods), we had loads of possibilities to check out the power of the HPI elements. We’re joyful to say, although, that the principle chassis stood as much as some critical abuse. Our solely actual situation was the ESC releasing from the chassis (a straightforward re-tape repair). The physique, nevertheless, didn’t truthful as nicely. A number of scratches, a torn rear diffuser and a pair of lacking headlight ‘grilles’, the physique is already prepared for alternative. Whereas we love the look of the Audi, we’ve additionally obtained our eye on the brand new Ford Mach-E 1400 physique set… Choices, selections.

Last Ideas
First off, we’re extraordinarily joyful to see HPI again within the RC recreation. They’ve been sorely missed in each the bash and racer communities.

That being stated, we’re additionally glad to see them nonetheless dropping body-oddities on the Sport 3 Flux chassis just like the Audi e-tron Imaginative and prescient GT (for one). This automobile, with a pair straightforward mods, will definitely carry a smile to your face as you blast by at over 60mph in RTR type. Add an even bigger battery, a gear change and that smile will get expotentially greater because the speeds get quicker.

We don’t assume this automobile is ideal (thus the unlucky low rating within the Efficiency division above), nevertheless it positively has potential. And it seems tremendous cool. And it’s fairly quick. Simply be ready to tweak it a bit for optimum efficiency!
