x5 rebuild

[Naushad]

Hi,

I am rebuilding an X-factory x5...I have a few questions...some may be silly

1. Apart from losi wheels what other makes can I install?

2. How tight should I adjust the slipper...I'm running on smooth surfaces mainly. If I run on grass what adjustment should I be making.

3. I am not sure, but I think the front wheels move independently of each other and the rear wheels. When I press the throttle, the front wheels take some time to roll. Am I right in saying there is a front one-way installed? I am not sure!

Thanks for your time
