Technical and Designing Review

Include with the CopterX 450AE V2 Kit is one set of wooden main rotor blades. These blades can be upgraded to carbon fiber blades if you are into heavy 3D flying, but there is nothing wrong with the supplied main rotor blades. The paddles are made from plastic with two separate flybar weights that can be removed for faster cyclic response. If you are a beginner, I will suggest that you fly the helicopter with the flybar weight first for extra stability.

The main rotor head assembly is made from blue anodized aluminum and is pre assembled at the factory. Two metal main shaft bearing blocks ads to the quality of the CopterX 450AE V2 Kit. The plastic main drive and tail rotor gear incorporates a newly designed dual cooling fan system that cools the electronics down during flight. Four precision aluminum laser cut side plates ensure for a rigid main frame, and gives the CopterX 450AE V2 helicopter a solid housing foundation for all the electronics and main shaft.

An adjustable battery tray can be adjusted to suite larger and heavier LiPo batteries. This will ensures for a perfect CG. The main frame base plate and landing skid struts are made from strong durable plastic. The aluminum landing skids are held in position with four rubber nuts and can easily be removed if needed for replacement. An aluminum tail gear drive set ensures for a perfect gear mesh with the main tail drive gear. The metal tail boom lock secures the tail boom in place with eight screws to prevent the loss of tail belt tension during flight. The CopterX 450AE V2 tail rotor is belt driven. I personally prefer a belt driven tail rotor system above a torque tube systems, so this gives the CopterX 450AE V2 Kit a few extra bonus points in my books.

The tail rotor assembly is made from blue anodized aluminum, and is pre assembled at the factory. The two supplied plastic rotor blades works perfectly, but can be upgraded to carbon fiber blades if needed. The feathering of the tail rotor blades are very smooth and will ensure for accurate pitch changes from the tail servo. Aluminum stabilizer fins gives the CopterX 450AE V2 helicopter a nice look and can be straitened after a mild crash. Plastic and carbon fiber fins usually needs to be replaced after a crash.

And lastly, the CopterX 450AE V2 Kit comes with a blue plastic canopy. The supplied stickers can be used to personalize the canopy. I found the edges of the aluminum main frame to be a bit sharp, so extra caution should be taken when installing the electronics. That is the only problem I have with this kit. Other than that, the quality and design of the CopterX 450AE V2 Kit is superb.

Assembling CopterX 450AE V2 Kit

Assembling the CopterX 450AE V2 Kit is fairly easy as 95% of the assembling was already done at the factory. Simply pop the supplied CD into your PC to view or print the manual. Follow all the steps and the helicopter will be fully assembled in no time. I got myself the CopterX 450 Electronic Parts Package to test their quality for this review.

The three swash servo's fits nicely into the servo openings in the main frame. The brushless motor has two different diameter holes for securing it to the motor mount. Use the two holes nearest to the motor shaft for a perfect fit onto the motor mount. I have fitted the ESC below the battery tray. This way it get sufficient cooling from the opening at the bottom of the canopy. Use the supplied double side tape to secure the CopterX 240Gyro on top of the tail boom lock.

Flying the CopterX 450AE V2 Kit

Any R/C helicopter will fly well if the setup is done correctly. My initial setup settings ensures for a gentle flying CopterX 450AE V2 helicopter. This helicopter flies very well with no unexpected surprises. Hovering is a breeze with the flybar weights, and gives extra stability. Transition into forward flight is very good with lots of power available from the CopterX 430XL 3500Kv Brushless Motor. The three CopterX 9g servo's works well with no centering problems. The CopterX 240Gyro and tail servo works well, but I still need to tweak it a bit for optimal performance. I'm using the 11.1V 25C 2200mAh BatteryHobby Lipo battery that gives me about 8 minutes of flight time. After flight, all the electronics temperatures are slightly warm, and is a good indication that all systems are working well together. There is no doubt in my mind that the CopterX 450AE V2 helicopter will handle any harsh 3D flying as the overall quality is very good. Great helicopter...Great flying pleasure...
