XRAY - Model racing cars

The grease tip will add a little friction due to the grease but this goes after running for a short while. Any squeeking can be many things breaks binding incorrect gear mesh on diffs, mesh on clutch & spur, Shimming to tight on engine to do with clutch so when it gets hot can expand & bind. Whishbone pins or anti roll bars all squeek after a time if run in dusty conditions. As you can see many reasons just a process of elimination.

Razo Im glad to hear you are able to make your car last as long as you say but switching your driveline to either one of my or extra's designs will eliminate all of the drag that Im 100% sure your car has. After just one race you could spin the wheels on my car and they would go around 3 to 4 times before stopping. Now its even smoother. Im willing to bet yours won't turn over one time. Too much drag and too much grease.

Zero I ditched the stock driveline and upgraded to the new bulletproof Mader design which is really just other Xray parts and a custom sleeve. Im in Urbana Oh where we are putting the best track is Ohio in right now. Go check it out at www.area54rc.com

can someone explain, what is the advantage of the 808 driveshaft system ?
or why xray wants to use it ?
I don't see any...

The benifit is that the driveshaft pin is captured when the bearing is installed for reliability. Also more room is gained in the center of the chassis and theres less spinning mass because theres no heavy coupler on the pinion gear. It also results in less parts. I really like the design but it failed the durability test time and time again because of the bearing issues.

in reverse, the pinion wobbles a lot more onto the conical gear
bearings are weaker
a costly gear crash can occur at any minut
it's a hazzle to remove the driveshafts each time, between the engine blocks
and the radiobox

less parts ?? :
2-3 bearings, a spacer, a pinion part, a driveshaft, a joint, 4 screws, grease..
with an xb8 homokinetic driveshaft, you have to unscrew, but one setscrew of driveshaft and pinion

Guy your preachin to the choir. Sounds like you need to upgrade to my system. Let Me know when you want some sleeves.

thanks but actually
I have a xb tq fitted with the rear
and soon front suspension of the 808

Sounds like a good combo. Post some pics when its done.

Which one of these are the rear and front axels we are looking for this mod?

Thanks

this one

KYOIF458 Kyosho Rear Universal Swing Shaft
and this one

KYOIF457 Kyosho Front Universal Swing Shaft

Yup those are the ones.

also xray sends the wrong inputs to other manufacturers too
like Serpent and also the new OCM, who designed the same driveshaft system
and who's drivers will face the same problems

very disappointed in xray there....

I just had the rear central drive shaft bend on my 808e. It partially collapsed the rear diff pinion bearing in the process. Everything was running fine afterwards, I picked up the issues during my regular rebuild

i hope the 2011 808 does the trick.. sucks we will need to buy new bulk heads,shafts,pinions,bearings etc..

And a chassis plate
