For NiCD Battery ONLY!!

For car and boat


  • Auxiliary safety device that constantly checks the pulse signal from the receiver by means of a CPU and turns on a fail safe (F/S) function if the pulse is disturbed by interference. When the power supply voltage drops, a battery fail (B-F/S) function turns on and moves the throttle servo to the position set (brake or engine slow) by a trimmer
  • Compact and lightweight design does not affect servo performance.
  • Response quickly to erroneous operation by interference, etc. and prevents loss of control of R/C models.
  • Quick recall function quickly resets the F/S function by normal servo output signal from the receiver when the interference, etc. disppears.
  • Use the FP-FSU1 with AM and FM system
