I've got a new Castle brushless conversion hardware kit for the HPI Baja, and a new Castle Mamba Monster XL v2, and a new Castle 2028 brushless motor (or a couple Leopard motor options also), and new 4S hardcase lipos. I've been hanging onto these items waiting to come across a Baja 5B SS roller, but I will gladly sell to you if you can get your hands on a Baja roller. You could definitely come in under budget and build an awesome 1/5 brushless rc with readily available upgrades and replacement parts. Let me know in half a month
