A newly desined twin rotor helicopter from Hirobo

MRC/Altech releases newly improved 50 size Vertol kit. Hirobo has modified the bird with a new main frame design, larger tank, additional body style (CH-47 Chinook - item number 0406904), and updated heads and swashplates. Controls are now electronically mixed via Hirobo designed control system included with the kit. A 3 axis gyro is also included as well as a Hattori 540 tuned pipe and a header. No more complicated mechanical control system. The starting system is changed to the shaft type like that of the Sceadu and Freya series. It is setup for a 50 size motor to carry the weight, and requires seven servos (3 for each rotor head and 1 for throttle). Body is unpainted fiber glass.
