esp if you run a high torque steering servo. I have a 1200mah battery and I get a couple hours of runtime. But you can get a second hump pack like 1100 or 1200mah and still use the 600, when your 1200 goes dead pop in the 600 while the 1200 recharges. The 600 should last until the 1200 is charged if you have a decent charger.
