Walkera 36 whatever. By the time you get the lipo, compatible charger, motor, and speed control, you have already spent more than you would on a Belt CP with spare parts, and it COMES with lipo, balancing charger, brushless motor and esc for only 180 USD plus shipping. With the MX 400 it is the same. After the motor, esc, gyro, radio set, any extra servos, battery, and charger, you will be way over what the Belt cp and extras will cost.
