This is an old model from Walkera. It's the first version Flying Boat #58. There are several videos on Youtube. It's new in original box. We have never flown this model. So we can't guarantee its performance. Recommended for experienced flyer. It's RTF package with 72MHz radio. The radio is an earlier version Walkera 4-channel 72MHz, which we don't recommend it be used. It's powered by brushless motor.
