It will probably be o.k. but it depends on the exact motor and what load it has (e.g. what gearing and what prop). Some 540 size motors will take a lot more than 30A if you let them.

BTW when you say 1000-2000mA I believe you're thinking of battery CAPACITY (mAh) not current. Any 540 will take more than 1 to 2 amps.
