While that will work, it sounds like you are adding a considerable amount of weight up high. While aluminum is light, it doesn't take much to have an affect on your COG.
And just so you know, I probably wreck more than you and the CF towers are holding up fine. They are much stronger than you'd think. I should see you at the MAW race.

Hey Brad does this mean you are gonna run Xray this year? If you are looking at truck body's that is a good sign. :D :D See ya at Wolfpack.


I'm probably gonna run Xray this year got a 2010 808, 808-e, xt8 09 and I am working on a xt8-e 09 have you ran you're new truck??

PROBABLY going to run xray this year? That sounds like one heckuva line-up of rigs for a probability..... :lol: :lol: 8)

I have ran my XT8-09 at the track only once and can tell its gonna be a beast when it "comes in". The RB WS9 is still a bit new and tight and I have yet to even touch the low speed needle from factory settings. :shock:

We are talking about 2 aluminum parts, approximately 3/4" x 1/4" x 1/8" in dimension. WITHOUT deducting any weight for the corners being rounded off or the holes drilled in it, that's .03675 oz each... or 1.0418 grams. You also have the 2 longer screws for the Mugen body posts, and the 4 aluminum locknuts for the original screws. Let's call it 3 grams total, or about .1 oz... probably less.

(If you doubt me, look up the density of aluminum... .098 lb/in3... and do the math yourself.)

You'll lower the CG that much by lowering the body.

Ummm... you don't know who you are talking to, do you? They used to call me "Captain Crash" but I got promoted... now I'm Major Crash... or just CTD (Crash Test Dummy.) I used to break the carbon fiber top plates (the ones that connect the servo saver and chassis brace to the bulkhead) on my Jammin' buggy. A few weeks ago I broke a shock bolt off.

I'd rather finish a race with a bent aluminum tower than DNF with a broken carbon one. ;)

STartin to sound like RCtech around here LOL! I personally prefer Carbon/graphite. But really the milled alum. weight is negligble at best

I never had problems with my towers...BTW they are graphite not real CF. Ive broken more Alum. towers in my time than these here and Ive been running this truck since june of 09, still got the same towers.

I agree with you. Please no offense to those who do like them and have spent time making them look great. I guess thats why they make more than one kind huh.

Id be happy with the current JConcepts one if it were stretched out to fit the 09 specs.
IMHO the Xray lid LOOKS as good as any other. Its just too thin and/or too expensive in comparison to others out there. I can see the smarts in it being lighter with paint. And I suppose as long as the benevolent Mr Hudy were providing me with a fresh new one every time the thin light one broke Id get along REAL good like that. :lol:

Regardless of all of this...the stock xray body is not practical and the Jconcepts one really just doesnt fit. Plus IMO, I dont like the look of it. The cab forward bodies that are out now provide better airflow to the motors, give better aerodynamic characteristics to the trucks and they LOOK like trucks too. Ive also found that my trucks jumping charactersitics have improved with this body as well and I know my truck well enough to make that statement.

Its all about preference, but many bodies are going the cab forward route these days and for good reason.

BUT I hope XRAY decides to make us a new body soon. 2 choices would be nice...cab forward and a normal one as well. I think we've gone long enough without a body for our trucks dont ya think?

I'm not sure what you mean "graphite not real carbon fiber." Graphite IS carbon.

I have no complaints about the new one, and I've never seen one broken. I've seen some of the Mugen guys break theirs, and some other folks, so I'm just being cautious as a "not so great" driver. I've yet to bend an aluminum one... and if something can be broken, trust me, I can break it.

As for the newer bodies... I like the fact that they paid attention to the aerodynamics, but absolutely hate the looks of most of them. It seems they could find a nice compromise somewhere... in fact, I think Mugen did a decent job of that with their stock body. :)

Not so....Graphite and CF are in fact different materials...heres a link...http://www.chem.wisc.edu/~newtrad/CurrRef/BDGTopic/BDGtext/BDGGraph.html

and if you scroll down a bit it says..."The biggest difference between carbon fibers and graphite is that graphite is flaky and breaks apart very easily while carbon fibers are strong materials that do not break until much more force is applied."

What did I say? "graphite IS carbon" NOT "graphite is carbon fiber." Note however that from the link YOU provided: "When vendors market "graphite fiber" products they are usually selling a "carbon fiber" product." I am pretty sure you're getting hung up on a mistake in terminology, and that the components are in fact carbon fiber... more than likely pre-formed sheet stock cut to shape with CNC.

Tomato, Tamater, Potato, Patater. I refuse to believe that XRAY Carbon fiber is anyhing less than the very best the industry has to offer.
None of it is indestructable. Obviously the stuff is CNC cut from sheet stock otherwise we wouldn't have to coat the edges with CA glue. If they made em by hand we'd be paying 1:1 Ferrari prices and on a waiting list.

Too bad "they" don't just make us a lid from the stuff and get it over with.... :lol: :twisted:

LoL...Ok man...I had motorcycle fairings made from real CF and I can tell you that this stuff is not CF. But anyways...good luck with your science project lol. :roll:
