Cheers for replies chaps.
What's the 50g bulkhead? Is there a part no?
Re steering - I ran at Worksop yesterday and it was again an issue on fast sweeping corners - the car won't hook in - it pushes on through the corners.
Do a test in your cars.
Pick it up and move one side / wishbone up to see the amount of bump steer - you will be shocked. What's happening - is that as the car leans into the corner - compressing the outer front wishbone - the bump steer is actually turning the wheel out of the corner - the wrong way!!!
I compared the Losi to a YZ2 - on the YZ it has very slight positive bump steer - so as the car leans away from the corner - it turns into the corner.
On the Losi - it has massive negative bump steer - so wheel turns away from the corner
Removing spacer on axle side track rod helps - but it's still there.
I know a number of people struggling with steering in low grip tracks - to the point where some have decided to run a different car....
I'm hoping in Astro etc it may not be a problem.
Re running diff looser - bad idea - last thing you want is the diff slipping - I know as I've already had to rebuild and replace balls on mine.
