Andy is spot-on,they make a 50 tonner move like a 50 tonner should.
The so-called "super-spins"?,what're they??.
My Tiger now performs a steady pivot turn on the spot without throwing a track,admittedly,
I've only tried it on newspaper(tracks full of dried mud see

)but on my work surface.
Previously it was way too quick to risk driving it on a surface four foot off the kitchen floor.
The acid test will be out in it's natural element(well,the garden).
Something else I did while the sprockets were off was to check them for moulding
burrs and pips.
Making sure the tracks can seat in the sprockets properly should help to reduce throwing too.
