hey guys just got a sc10 and will start putting it together. I know these questions have been asked but it will take forever to read all the threads.

Is the chassis plate a must have?
what pinion is a good place to start with a 17.5 brushless and lipo?
what problems has everyone been having and what can I do to resolve these during the build?
does anyone have a good setup for dirt


If I have missed anything feel free to chime in and let me know

Thanks
