Hi party people,

I want to make a decently hard limit of $600 buggy build but I have absolutely no experience the race track. All I know is they do 1/8th scale and 1/10th buggy which has got me super interested. I made a build and would like some critique on if these are all compatible and things I may have missed or need to know.

Assume that if you do not say it, I don't know it.

And I have a Spektrum DX4C DSMR Tx that I want to use.

1. What Rx do I need/is best for quality and budget?
2. Will they let me race this setup on local clay/dirt track that allows 1/8th (that's all they say on website) or are there something I need to know?
3. Is this good enough once my skill catches up and I learn how to drive better where this will compete on track?
4. Is there a better price/value for some of these parts or is this about as good as I can do given budget limit?
5. For off-road Force track layout that is outside with clay/dirt what are some tires I should look at?

Thanks so much for taking the time to help a noob out!
