BLH1650 E-flite Blade 450 3D Helicopter BNF: 420H Brushless System, Digital Servos, Spektrum Receiver Installed, No Charger, No Battery - Preorder

• The DS76-series servos are specially designed to deliver maximum power and precision for extreme 3D heli flight
• The G210HL gyro uses the latest in MEMS technology to provide amazing holding power during the most aggressive 3D maneuvers
• The robust 35A speed controller is engineered to efficiently channel the high current flow of most any high-C 3S Li-Po battery
• The compact 4.0 gram AR6115E receiver provides the superior response of Spektrum DSM® control as well as the benefit of ServoSync which dramatically enhances the precision of any CCPM heli
• The rotor head mechanics have been optimized to provide the most aggressive 3D control response possible

The Blade 450 3D BNF blasts 3D heli performance to new levels of precision and power. It comes completely assembled and equipped for aggressive 3D aerobatics with the kind of pro-class electronics and mechanics you would expect to find in more expensive kits that take hours to build. It’s even been flight tested and had the rotors balanced at the factory so you don’t have to do any setup. Simply add your compatible transmitter and charged Li-Po battery and fly.

The Blade 450 3D uses a new design on the main rotor blades (BLH1615). The blades used in the Blade 400 3D look similar but are not the same (EFLH1415A). Do NOT use EFLH1415A on the new Blade 450 3D. Although these blades will work fine on the Blade 400 3D, the Blade 450 3D is a more powerful helicopter and using EFLH1415A will create an unsafe condition. BLH1615 is safe to use on BOTH the Blade 450 3D and Blade 400 3D.

To check if your blades are the new BLH1615 design, simply look at the mounting hole. If there is a brass insert, the blades are BLH1615. If there is not a brass insert present, the blades are EFLH1415A and should not be used on the Blade 450 3D in any circumstance.
