T-REX 700E F3C Helicopter


F3C is currently the only FAI recognized RC helicopter competition class. The competition event is focused on the precision and completeness of flight maneuvers, critical not only to the contestant’s expertise, but also the design of helicopter itself. Based on the need of F3C market, Align designed the value priced T-Rex 700E F3C using its technology and experiences gained over the years.


T-Rex 700E V3 continued the legacy of the superior 700E by adding numerous new features: New design 700 rotor head with more adjustability, enabling more dynamic ratios for enthusiasts to choose from. New latch equipped battery mounting assembly with CNC aluminum alloy mounting plates for ease of battery replacement. High spec MOD1 112T helical main gear paired with 12T motor pinion, with increase gear mesh surface to withstand the monstrous power load.


High quality tail gearbox with thicker side plates for increased rigidity; Teflon material are applied at tail rotor control rod and bellcrank ball link areas for increased longevity and minimized interference; Carbon tail pushrods with new pushrod guides for more precise rudder control.
