I can't speak for the eb48 specifically, but I practiced with an Eco with a 2s/Tekin pro4 4000/rx8 setup on a smaller (36x98) indoor clay track, and it was awesome. Plenty of top end speed geared 46/13 and cool motor temps, too. I would've stuck with it, but some guys at my track weren't happy about having ebuggies out there so I converted my buggy to a sct.

i've also been running my EB with a 2s 540 4 pole setup. I'm very happy with the power and speed I get out of it. The temps are great and if anything, the car is a bit too light. I'm going to keep running it like this for a while and swap back to 4s when the SCT410 comes out.

Really the EB48 is the best buggy out. It drives great and has done the impossible, it is both light and built like a tank at the same time. The biggest advantage the EB48 has going for it is the low and centered weight. But it still has enough weight to stay settled on a rough tracks.
The term "polar mass moment of inertia" comes to mind when I think about this car. Google the term with reference to racing and you should find some pretty good reading material. The EB48 keeps the polar moment lower than other cars out.
Now a car with true 50/50 balance (EB48 should be close) will always push at corner entry. This is because an additional lateral force is applied to the front tires but not the rear until later in the turn. Now the push can be tuned out with a number of settings but corner speed is all about staying neutral.
A car that is heavy in the back (say serpent) should theoretically turn in better but scrub speed as it swings it's weight through the turn (assuming you break traction). In the end the car with 50/50 will keep more corner speed but may not be the easiest to drive. It needs to come in smooth and exit smooth to keep the advantage. But driven at the edge of the traction limit 50/50 will be the fastest because all 4 tires can apply their max force.
I do not own an AE 8.2 but they seem pretty good but very heavy. They look and sound like they land jumps very hard. They turn well but look like once they lose traction it is hard to get it back.

My main reason was weight. I have been running an RC8 in one form or another for the last 4 years. It started out as a RCPD converted RC8 and it drove like total crud. I then switched to the RC-Monster RC8 conversion and it was better, but the super wide chassis and the crazy drive line angles did bad things for the car. I then constructed my own conversion that used parts from the RC-Monster setup and the stock chassis. I kept the drive line closer to the original offset and use the battery tray and motor mount from the RCM setup. This setup was almost identical to the AE conversion in terms of weight distribution. The car was pretty good, but still lacked stability off the jumps. The final conversion was to the Tekno V4 setup and it was like driving a completely different car. Cornering was improved, jumping was more stable and rough track stability was better. I didn't change anything else about the car so in my mind the difference was the layout of the chassis. Seeing that the EB48 was the same layout and the car as a whole was about a pound lighter than my RC8, I couldn't resist. I haven't had much wheel time with the EB48, but from the time I have had it seems to drive similarly to my RC8 with the V4 conversion. Very quick through the corners and very nimble.

Rc8.2e is only a year old, so i'm not expecting a new car out of associated anytime soon. The eb48 is mlst likely what i'll be running next season, but i'm still waiting for more kits to come out to be sure.

Main thing that I love about the EB48 is the layout. Having owned back in the day the RC8 conversions from RCPD as well as others in a variety of vehicles, getting that battery close to the centerline really made a big difference when I owned the Hyper 9E.
And the benefits in general for layout I saw this summer when a Durango was going toe to toe with a Duratrax DRX8E in the turns. Corner mashalling that race, you could see how quickly it could take the corners where the durango kind of fought its rear end to get around the corners as fast.
Being a Tekno fan with my D8, the choice was pretty easy to make lol.

yeah, I just did lol. Mainly contrasting the layouts, but to be honest after looking it over and seeing it go, after you upgrade it with a few parts for racing, its not a bad vehicle. They have come a long way.
But again, main point was to contrast the layouts, there were no EB48's out here at the race I attended.
Hope to change that

I race 1/10 mod 4wd buggy and the EB48 to me feels almost as light and flickable as the 1/10 does where my RC8 and Tekno D8 feel much more "numb" is the way I would describe it .
At first I had to get used to how quickly the car would respond to input changes but once I got used to it I started to finish races on the lead lap with the fast guys instead of going down a lap by the end of the race . I was only able to get to 3 races on it after I got it but I was noticeably faster right from the first lap with the EB48 .
The outdoor season is over for now around me but I cant wait for next season and some more wheel time ....

My rc8.2 tekno v4 (b4 was a 8.2e) maybe has marginally quicker initial steering response though. Shortcoming of eb48 is the car is so easy to drive fast so i just keep the car for racing days only ;-) The key disadvantage of my 8.2 is the weight of the car, other then this the car runs and turn really well. And the car is more exciting to be driven especially given im still using metal spur and the sound is as if a big monster is coming when accelerating... Haha
