There is still more grams to shed by drilling holes in the front and rear braces like what Kortz has done. I like the blue anodised parts too. BTW how many grams overweight does a 8.5 weigh as standard? what is the legal weight limit for racing sanctioned events?

As they no longer have the fore/aft support from the upper a arm. Also, what modifaction have you dont to the spur and crown wheels ?

You can and more than likely will bend a shock tower under a heavy crash, but that's the only downside I've experienced. You can break an arm easier too, but I've not had that happen. The upside is the buggies steering is so quick, and precise, and it'll go through the rougher sections of the track with a lot more speed without upsetting the chassis... It's a, I'll take the "good" over "bad". I'm faster and much more consistent with the front upper a-arm setup, so I'll be staying with it... Hope this helps... Have Fun...Burn Nitro... Rob B.

I've made up a set of Kortz arms for the front, going to test them later on in the week. I did notice that the front end is a lot more free with the Kortz mod. I've been doing a bit of weight saving with the lower suspension arms, chassis braces, steering arm and radio tray. Next to do is the chassis, from what I've calculated I can get around 100g out, maybe more if I cut the chassis sides down.

There is a tiny bit more wobble in the hubs. The buggy definately feels quicker through the rough sections. Back to top Author Message Nitrohouse Joined: 26 Oct 2005 Posts: 3669 Location: Irvine, Ca.

The Hyper 8.5 is right at 8lbs 7oz stock, depending on which engine pipe and radio gear... Mine is now just a hint over 7lbs 2oz...And could be make even lighter if I really wanted to...

Or can I buy direct from them and have them shipped to US? You should be able to mail them in a envelope?
