Cheers for the heads up, not much point running the included filter, cant get spare ones. I was goin to try run the x6 elbow with the rest of the air filter mount off the 5R with 5R powersaver filters.

I would run another filter set up if I were you guys until this issue gets addressed. And before you ask, yes it was on tight, yes it had filter oil and yes it was installed correctly.
This could be the case as the filter seems rather tight on the assembly and may bunch up.
When i put the air filter together i made sure the filter spread out and I always flood the ends with extra oil just to help them seal
This being said im going to keep a close eye on it now!

I know there are a ton of pics of peoples buggies, but i was wondering what were the most significant changes Mugen decided to change with the all mighty 5R...so i took some comparison pics...i have to admit, its pretty significant just by comparing the chassis and diffs alone!

If you look at the chassis, Mugen didnt just go long like most were assuming, they actually decreased the actual width of the chassis, and decided to move the motor assembly forward, and ontop of all that, they didnt even change the chassis length at all! also it seems to be hard anodized, which looks awesome!

Also they reduced the weight where it counts basically, right on the drivetrain (which is no secret) but when you add up all the numbers, its allot considering where they reduced their weight.

I compared the old center diff to the new center diff, so everybody can get a general idea on how much they took off overall. but on the center diff alone, it was a 10 gram difference, so if you times that by 3, thats nearly 30 grams right off the drivetrain alone, thats not including the driveshafts and so on, as there was some weight removed from those areas as well. anyhow here are some pics so you guys can get a general idea of what i am talking about:

here are the weight differences between the 2 chassis...I realize the used 5R chassis has dirt and all, but keep in mind its a used chassis that was wore thin...like razor thin in the rear lol so the actual stock 5R chassis may weigh even more. but here are the weight differences between the 2:

Default X6 Diffs are lighter and heavier.

Jesse,
Good visual on some of the X6 weight reduction.
I would like to point out one other innovation with the new X6 Diffs. Yes, your pictures show the overall weight reduction. Yet, the design is also beefed-up. Seems like a paradox from a distance. Diff Cups, Cross Shafts and Satellite Gears are all unchanged. But, those old 2.0mm drive pins the light-switch-throttle truck drivers kept shearing-off have been replaced with new 2.2mm Pins. The 18T Sun Gears are new with a larger slot to fit the larger 2.2mm Pin. The new 18T Sun Gears also appear to be cut slightly deeper making the teeth bigger. The new 44T Spiral cut Ring gear, 46T Spur and both types of out drives have been lightened more than 10 grams. Because the new bigger drive pins are heavier. Those tricky Mugen designers snuck-in a weight increase!

Jesse, Do you have different weight oil in those diffs? HeHeHeHe.

We weighed some cars at the races this weekend. Losi eight was 7 LB 9 oz with half tank of fuel, Kyosho MP9 7 LB 10 oz dry fuel tank, and my MBX 6 was 7 lb 7oz with half a tank of fuel!!!

I ended up going to 350 front, 300 rear for the shocks. And dropped the front diff to 4000 and the rear to 1200, and also brought the rear camber links in one hole. These were all changes from the stock setup which I tried first. I felt the car handled bumps and rotated better after these changes.

I have never driven an offroad car that comes out of the hole as hard as this one does. Pretty fun!!

Disregard the above post the grooves arent needed at all after a bit of fact finding they are meant to be like that.

actually i took out all the diff oil from the old center diff and left the 5k diff oil in the new one...

so if i added a small amount of diff oil, that might raise it up a tad bit for the old one, but i made sure i took that into account lol

and yea, you really dont need grooves in your outdrives, the Xray doesnt have grooves as well and runs just fine!

What sort of track surface were you racing on.

That 5R chassis must be REALLY worn. Brand new MBX5R chassis weighs 313 grams so the new chassis is a LOT lighter (51 grams to be exact).
