2007 Newest DragonFly 53#1 is more powerful, flies longer and has better servo resolution for more precision flying indoors and outdoors. The helicopter is easy to fly and spot landing on the kitchen table or other platform presents an entertaining challenge. You will also be impressed with its stability! The DragonFly 53#1 has two sets of main rotors and a freewheeling tail rotor that does not affect flight. The contra-rotating main rotors eliminate the need for tail rotor compensation becae they move in opposite directions, canceling each other’s rotational torque . In addition, the dual blade setup provides more gyroscopic stability. In plain English: you look much better on the stick than you thought you would. The DragonFly 53#1 comes with a 4-channel, 72mHz transmitter, 7.4V 1250mAh lithium-polymer battery pack, and charger. The transmitter has two features worthy of note. On the front there is a color battery meter which makes it easy to tell when it is time to replace the alkaline batteries. On the back, there are open dip switches for non-standard heli flyers to alter the configuration of the radio to a style they are acctomed to ing. Optional Li- poly battery will help to achieve better performance and longer flight time.
