Thanks Marco,

It's probably 1 full pound lighter than a V4 D8. Our test cars are 7lb - 7.5lbs depending on what system, battery, and options we're running. It is the lightest buggy we've tested and we've tested them all. XRay is the closest in weight comparing rolling chassis.

We weighed a friend's 811Be and were surprised how heavy it was (8.2lbs with a Tekin and 2x 5600mah packs).

I ran a Neu 1509 1.5Y (2400kv) with a 4s/4400 pack and the car just tipped 7lbs. That setup is good for at least a 10 minute main.

I'm currently running a Tekin 2050/RX8, 4s/5000 and the weight is around 7.5lbs.

Austin Blair recently installed a Castle 2400kv SCT motor and dual 3800mah shorty packs. He is below the ROAR weight limit at this point. He got over 11 minutes on the setup indoors and over 8 minutes outdoors with those tiny packs. That's impressive when you consider he drives harder than just about any pro driver out there.

The beauty of it all is that there are so many options. The standard 1/8th buggy motor in the EB48 feels like a 1/8th truggy motor would in most other E-buggies.

I notice you have a rear chassis brace on this model. What made you decide to go back to a rear brace over removing the need for them on the V4?

Thanks Kufman. Diffs are 10/40 (4:1). The spur is 44t. We've been running 15-17t pinions/bells for most of testing depending on track size/conditions.

that's great.......lighter than V4 D8 is already a good standard in my point of view......
hope everything can keep on schedule~~~i'll probably get one once released

Options.

I think only one of us is running the rear brace right now. There are 3 braces on the car. One front brace (always recommended), a center diff brace (optional) and a rear brace (optional). You can tweak the flex to your liking. The best combo so far is front and center, no rear, but I want to test front/rear, no center a little bit more.

BTW, we will have setup sheets available at launch! We plan on releasing 3 setup sheets that you can start from. Basically a setup that pushes slightly (easier to drive), a balanced setup (recommended), and an aggressive (MAJOR steering) setup.

One of the things we found is that the car is very responsive to setup changes and you can really tune it to your individual driving style. You can setup for tons of traction or tons of steering and it's easy to adjust that bias to your driving.

But, the car doesn't just push OR steer. During testing, we drove dozens of other 1/8th scales back to back with ours to see what was working on other cars. Where were the other cars beating us. Did they steer better off power? Did they stay flatter in the corners, etc.. What we wanted to do was to beat every car in every category. That's not always 100% possible since a gain in one attribute usually results in a loss somewhere else. But when you combine the features, weight, suspension geometry, etc we've come very close to having a setup that is better in almost every way than the conversion we've been driving up to this point.

Three quick questions:
1) What kind of shafts did you use on front and rear? (universal, cvd..)
2) Are the screws metric or imperial?
3) What about the angle of rear dogbone?

Perfect, my birthday is June 29th and I know what I'm getting

Will I be able to purchase it from SDRC as well?

We used dog bones in the center. CV's with captured pins on all 4 wheels.

Metric screws throughout.

About the same angle or less than our V4 conversions on the rear dog bone. The front is perfectly straight and does not wear. The rear will eventually wear, but the angle (~6 degrees) is less than most nitro driveshafts and far far less than say a Losi or HB front shaft.

I know this may sound completely backwards to your business model, but any plans on releasing a nitro conversion for us guys that like to play with both power sources?

Really nice work tekno!! I believe that this chassis layout will become the "standard" for all e buggy and e truggys in the future. Sort of like the nitro Buggys all basically look the same now with just minor variations to component positions. I've definitly got this on my list as one to watch for the next time I need a new buggy. Nice to see someone taking the lead on this rather than just putting out another conversion.

Why center front CV on conversions and dogbone on this? Did you tried both and decided to dog bone?

Since the center and front diffs are lined up straight there's no need for a CV.
