*Note: This radio-controlled helicopter is not a toy! The tips of the blades travel at an excess of 150mph. Do NOT buy this for your child to play with! These helicopters are designed for experienced radio controlled hobbyists in mind.*Align has a huge line of radio-controlled models, and I have purchased their smallest one, the T-Rex 450. More specifically, the SA version, which has a plastic rotor head and tail, but aluminum side panels. I bought it for $260 at my local hobby store, Hobby Hangar. However the $260 is just for the airframe and a brushless motor and esc. If you want it to fly, you will also need at least a 6 channel CCPM computer radio system, three micro servos, a gyroscope, a micro tail servo, and a 3 cell lipo battery. For this review I will be using a Spektrum DX7 radio system, three s75 servos, a Futaba GY401 gyro with a HS-56 tail servo, and an Align 2100mah 3s lipo battery with a Dynamite Vision Peak Ultra charger.
The 450 comes 90% pre-assembled, Align leave you do install the radio gear and electronics yourself. This took me 3-4 hours. The biggest pain was to install the three S75 servos. Align's manual does not provide much information on how you screw the servos into the frame, so I spent a good hour trying to screw in the servos before I finally got them in. Other than that, it all went together smoothly, and I was off to go flying.
All went well flying, and now I am on my 32nd flight, doing forward flight. My only other concern for this heli is that it has plastic tail belt pulleys, I would rather much see metal ones, but it is a simple $20 upgrade for them. I am very pleased with the helicopter, and I would recommend it to and experienced hobby-grade radio controlled modeler. Remember, this is NOT a toy! People can be severely injured if they don't know what they're doing around these models. This is for experienced, radio controlled modelers only!
