Schumacher Mi4

I wish I could find another SST 99, that was a good car. This car looks really good, I just can't afford it

All, don't concern yourselves with the motor twisting. We've been talking about this one today. Regardless of what has been posted, none of us have suffered from motor twisting - period!
Myself and Chris G had shunts when we ran today that would have caused a motor to move IF there was an issue - neither motors moved. Simple as really.

I know it's probably odd lens focal distances, but the steering bellcrank looks to have some odd angle in it (in a couple of photos). Is it intentional, bent or prototype parts in short supply?
Looks like the left side is bent...

I think the angle is intensional so you can change the ackerman by adding or subtracting spacers and moving the pivot position front or back. Thats the way I see it.

Hi All
I will try and answer as many things as I have seen posted, some may be off other forums
The car is very good, clearly faster than the Mi3.5 for me anyway. The areas that needed looking at have been addressed without just copying the crowd. Longer top deck. two piece rear bulkhead.
The Motor mount is fantastic, Its almost the perfect design as it does not touch the chassis at any point, so the flex of the car is perfect left to right. The clamp works 100% fine, never had it move never seen it move.
The steering that nobody seems to have noticed is very cool, the mounts angled in so the ball joint does not over rotate.
The drivetrain is the same as on the Mi3, diff spool center pulley spur belts driveshafts etc.. Only thing new there is the diff and spool pulleys are now lighter and narrower..
The layshaft is hard to explane,but a very cool design the way it works.
on the new suspention mounts you can still alter the width and toe with shims, just the height is fixed, personally I will never move that, its in the correct place.
The upper camber links are as adjustable as before just in a different way, there will be various brackets to alter the width in half mm steps and you adjust the height with shims. the kit ones I will use 99% of the time..
I read that I was breaking lots of arms, that was Mi2 arms, I broke 4 I think But that was why Schumacher made the Mi3 arms! They dont break, Or at least I have not broken any.. The reason I was running Mi2 arms before someone asks is the Mi3 is a little heavy so I used them as they are lighter, but as the Mi4 is lighter there is now no need..
Driveshafts I have bent one bone since joining the team..
The top deck angle is a secret, but It seems to work! Today I did my fastest run ever on my local track, first time on it with the Mi4. Personally I am very happy with the car!

Hi, can we get some pictures with the electronics installed? Thanks.

The angle is intentional to allow better articulation of the track rod arms.
