Does the stock chassis fit it? Also this isn't a stock class. I'm trying to keep this in budget so I'm thinking of going with the Hobbywing Combo(7800KV Motor, ESC, and Program card for $47). Any advice about that? I'm really really trying to keep this under budget but it's quickly sailing over that mark. This is supposed to be just a relaxed 3rd class for me. Thanks for all the advice.
