Them Tenshock motors are no joke for the price crazy mid/top end power ! I run a 4600kv on a big track and a small indoor one which im planning to get the 4000kv for more torque.
Although you do need to set the LVC higher because they do demand a High C" and MAH rating lipos.
I would recommend taking a look at the New Tenshock motors when they come in stock im hearing there better than the old ones.
