XRAY - Model racing cars

Hello,

Im search ECS Drive Shaft which are the Beste for the T4'14 ?
Have heard that the original ECS from Xray are not so good, is that true ?

Thanks

I ran the genuine Xray shafts last year. Good quality as you'd expect, and very little wear. After about 4 months I snapped a dogbone. Shortly afterwards a teammate snapped one in the same place (similar age parts). Which to be honest isn't bad going running 13.5 boosted as thats a fair bit of power.

But this year I went for the Roche DCJs instead. I wanted to find something stronger, and preferred the c-clip design to grub screws.

So far the quality is as good as Xray parts. Zero wear or issues. Can't comment on reliability just yet as they're only 2 months old, but looking good.

where do you get the roche dcj's dale?

just to add to this,i picked up a set of spec r shafts and although i was initially put off the brand i found them well made with no slop,ran them for one meeting so far so will update if there are issues with these,so far so good,i did have a lot of slop in the bearings so i have shimed all the slop out,i used small 0.1/0.2 and 0.3 shims that i had lying around,so with 1.8mm of shims between the bearings and 0.3 mm shim between the bearing and pin,once all tight i have no binding and the smallest amount of slop,it could be measured as 2 deg of slop before,now id say i have less than 0.5 deg so hopefuly this will translate into faster lap times,im hoping the front will now feel more planted

Hi

Just want to add my input on the ECS questions.

I have just build a second hand T4 2014 , but with brand new xray front ECS. Have not ran 20 akku's when the inside just snapped under braking on asphalt. Have had no big crash , not hit anything. After xray changed to the 2 mm pins , the dogbone part of the ECS have been way to fragile. Everyone is looking at other brands for ECS , they last longer and for half the price.
This is a mayor part for Alex, mario and Martin to design a new ECS. The 1,5pin broke at the flat part , mayby to use a clip as many other do and then go back to 1,5 or 1,8
