I’m pretty new to the RC game

I only have an Arrma Senton BLX 6S, which is an awesome truck, but I’d like to get something a little bigger to handle taller/tougher/rocky terrain

My only requirement is that it’s electric

Arrma Granite and Arrma Big Rock both look nice for the price ($300ish). What others should I consider around this price point?

Please also recommend LiPo batteries if you recommend a truck
