Linear servo actuator for trim surface control in ultralight aircraft

Trim Servo Pandora T1

Compact linear actuator for the trim surfaces of ultralight aircraft. 20 mm stroke in 9.5 s, 68 N (7 kg) load, integrated position sensor, self-locking rod on power loss. 136 g.

Pre-order — expected availability late October / early November 2026.

The PandoraT1 servo actuator is designed to control the trim surfaces of ultralight aircraft. Its extending rod with a 20 mm stroke moves the trim surface smoothly and precisely: the direction of travel is set by the polarity of the supply voltage, while a built-in sensor reports the current position. The unit detects both end positions internally and stops the drive automatically once they are reached, and if the power fails the rod stays safely locked in its current position. Measuring just 68.4 × 68.4 × 28.45 mm and weighing only 136 g, the PandoraT1 is equally suited to installation in the wing and in the tail surfaces. Fitting is straightforward: four M3 screws on the surface, or recessed into a cut-out. Two actuators can also be wired for synchronous control of two surfaces. For a complete electric trim system, add the CTRD relay polarity switch and the TRIMIND position indicator from the LA range, or go straight for the PandoraT1 KOMPLET set.

Wire identification

  • MOTA grey — motor supply, (−) extend / (+) retract
  • MOTB white — motor supply, (+) extend / (−) retract
  • POT_HI orange — position sensor supply (−)
  • POT_MID green — position sensor signal (OUT)
  • POT_LO blue — position sensor supply (+)

Installation
Secure the actuator with four M3 screws (surface-mounted or recessed into a cut-out) and make sure it cannot work loose. Check that the rod cannot foul any surrounding parts anywhere along its travel. Then connect the control accessories and an adequately protected supply voltage. Direction check: with the positive terminal on the white lead and the negative on the grey lead, the rod extends. We recommend running the actuators to the end of their travel before every flight in order to synchronise them.
