Many thanks for that - glad somebody is still here! RCTech is very quiet these days.

I have sorted the problem with wander steering once and for all.

Firstly, we needed to get a bespoke spring, with a higher rate and more space between the coils.




Here, the uprated spring fitted to the steering assembly.

Compare this with the stock item, which would only give reasonable steering with the road tyres when really pre-loaded.



Next, I reduced the toe-out to 1°, which should improve straight line stability. As it was out of the box, it was more like 3° which on reflection for a car this size running on tarmac is excessive IMO.

The horses certainly love the Kronos XTR! It was so funny watching them chase it. Bless em'!
