This is the new 2021 version of the F-16 electric retract set from TOPRC. It also contains a complete redesigned and very robust retract controller with brake and gear door functionality. The controller contains a smart programmable controller which is able to control the retract motors, brakes and the door servo's. The controller also contains a test feature to open and close the retracts.
The gear door sequence can be programmed.
The 2 brake outputs are controlled by a receiver output channel and the 3 gear door servo's are controlled by the retract open/close input signal from the receiver.
