yes the batt. box is almost exactly the same as stock, But I would advise you to purchase the nicd batterys for the transmiter
and receiver.
* Optional Receiver NiCd: (FUTM1295)
* Optional NiCd Charger: (FUTM1830)
and the transmiter batt. futm1462
in the long run you will spend less---no expensive AA batt. to buy just recharge and with the charger you can charge both batts at same time
