Ive got a t4 2016 and want to put the flex linkage from the 2017 t4.is this an easy bolt on or ??

the short answer is no. The servo mount & motor mount which have the necessary attachment points are not compatible with the 2016 chassis, due to pins that extend from the servo mount. the 2016 also does not have the screw holes in the chassis for the flex plate or linkage. You would need a 2017 chassis, servo mount, and motor mount to make the system work.

You'll need to use some ball nuts (so you can screw into them from underneath), the ball cups and a 39mm turnbuckle. I used Awesomatix parts as they were what I could get hold of at the time.
At the rear, use a 10mm countersunk on the forward hole of the motor mount plate, and then screw one of the ball nuts down on top. I spaced it up with a 1mm shim as well. (Alternatively, you can use a grub screw into the plate if you don't use the forward hole).
Up front, mount it into the ariel hole. Again with a 10mm countersunk, 3mm shim, then ball nut.
Then set the turnbuckle so it's loose and free to move when the the top deck is on.
The front hole is a little off centre, but doesn't seem to affect the car too much. Spaced up the way I mentioned, can still fit the Xray weight in the centre too.
And for what it's worth... I recently did a back-to-back at my local track (outdoor asphalt, medium-high grip) with the three different flex options on my '17. No link, Carbon brace, and turnbuckle.
Turnbuckle was not only fastest, but also consistently as quicker too. Nothing in place was about 0.2 down on fastest, but more inconsistent also. Carbonbrace was as consistent, but the car lacked overall bite, so was slower by about 0.3 over the turnbuckle.
The turnbuckle seems to affect a few things - more positive on the brakes and on throttle, but also rotate quicker through the middle of the turn. So a bit of a win-win tbh!

Excellent work ed.thanks for the info i will try that on my car also

and I suppose the goal is to link the longitudinal aluminum structures on the chassis, in this case, the motor mount and the servo support. Here you are just "extending" the motor mount, I suppose it is different at the end. I would avoid this solution, especially if the hole is not perfectly centered...

Both solutions achieve that, albeit with the '17 being more refined with the link being designed into the car.
At the very least, I'm just offering the option up for those who want to give it a try... and happy to state that a large majority of Xray's at the worlds ran that exact setup (only the team guys had the '17's then), and I'm under the impression it had been tested on the team 16's for quite a while before then... take that as you will.

actually i suppose that is the antenna mount hole? It might be as central as the middle motor screws are. The servo mount wouldnt be centered and i was thinking if someone connected to that, the link would be compressed or stretched when the chassis tries to twist.
I like having my cap there though.

Hi guys
I realized that my T4 2016's servo moves slightly whenever I made a steer from my transmitter, and this creates a problem of not aligning straight whenever after making a turn. The screws attached to the servo are tight enough.
I'm using Sanwa low profile ERS-96E servo and Hudy direct servo horn with 7mm shims connecting to steering link.
I can't find any answer on the Internet pertaining to this issue, and can anyone please advise me on this?
Thank you.

Two things come to mind, are you mounting the servo directly or have you used the rubber isolation tabs? Could you not have your end point adjustment on your transmitter set so your not crashing the steering blocks into the c-hubs and possibly tweaking something in a way that it doesn't return to center?

You want these.
