Hi Guys...I have one of the first assembled MI4s,so I thought I would give my comments...Overall I was quite impressed with the build.I put the car on a Hudy setup station and it was almost the same as the tarmac setup in the book.Slight variations with droop and camber but overall pretty good.The only major problem (no one seems to have commented on )is the steering assembly is not high enough to clear the servo.Must admit as my car was in the first batch it was missing the bag with the servo posts/arial post etc so I used some servo posts from the 3.5.I had to put a spacer under the steering post and this fixed the problem.
Everyone...please locktite the screws that hold the outdrives onto the spool!!!!!otherwise they will come out..as one of mine did...even though they had used some form of threadlock on the screws.
I found some of the screws in the chassis were not flush ...I think this might be due to inferior screws rather than the chassis..
The car handles vey well out of the box..going to try harder springs/oil
this is just my 2cents worth

It was the basic setup ? Or it was the setup of Grainger ?

they keep the set-up MI3.5 :
front: blue spring, 0.5
rear: white spring, 1.5
Yoann bukowsky: "the test is good now! the rear block have more grip than the MI3. But the MI4 has lost directivity ! I' think we can take the same front train MI3..."
Alexandre Laurent tell me and he say : "I recive the new chassis 2mm MI4. the car has more flex and i doing more directivity!"

Hi Heavy, there should be a small amount of play in the layshaft, any more than .2-.3 of a mm can be removed by adding a shim or two.As for the ball stud nut rubbing on the servo case i had the same problem, the easy fix is to use a slim nut and then file or dremel of the remainding ball stud thread or just dremel the existing nut and thread by approx 1 mm. hope this helps Scott.

Use a pair of 0.5 or 1mm washers (depending on servo height) between the alloy steering housing (U3493) and the c/f arm (U3501) then remove the washer that's underneath the ball stud on the c/f arm (U3501) to bring the height back down again.
These washers should be included in the tuning/spares bag and this will not affect the steering geometry at all.
