    Mr. Rouelle, thank you for your valuable comments.


    We see now that we have chosen the wrong approach and started modelling the frame prior to the choosing mountings instead of the opposite.

    We have already written a list of mechanisms to be mounted and work on them.
    We are rebuilding the frame based on mounting points and make a stress on the templates pass. Of course, we do not forget the driver’s safety and try to find the balance between the safety, rigidity and accessibility

    Mechanic,
    Charles Kaneb's use of the word 'el-floppo' to describe tyres is probably a poor use of slang.
    What he is talking about is a current generation of FS tyres that have high grip but low lateral stiffness, especially at low inflation pressures. Hence they tend to 'flop' around somewhat in use.

    Remember, the choice of tyres should be made very early in the design process. Make sure you read the 'sticky' tread here regarding the 'Tire Testing Consortium' or 'TTC' as there is a lot of knowledge there about tyres.

    "el-floppo" is an entirely appropriate use of slang here!

    Our tires give over 1" of lateral deflection at maximum load. If your design does not account for that, you will choose different front and rear track widths than if you do. They also deflect vertically - enough to give .3 deg/g roll in the tires alone. You can find yourself scraping things you wouldn't think would get near the ground.

    Charlie,

    I never disagreed with your summation of current tyres, just that I suspect 'el-floppo' probably doesn't translate well into Kazakh!

    Mr. Clarke,

    Yes, you are right. We just couldn't find the equivalent translation for that tyres. Thank you for description.
