What to do if LED on Horizon Hobby UMX PT-17 receiver flashes rapidly after binding?
- P

  If the LED on the receiver flashes rapidly and the aircraft doesn't respond after binding, there might be several reasons. Ensure you wait at least 5 seconds after powering on the transmitter before connecting the flight battery to the aircraft. If using ModelMatch™ radios, select the correct model memory on the transmitter. Also, check and replace or recharge the flight battery or transmitter battery if the charge is too low. The transmitter may have been bound to a different model or with a different DSM Protocol, so select the right transmitter or bind to the new one. Finally, move the aircraft and transmitter away from large metal objects, wireless sources, or other transmitters.

Why does Horizon Hobby UMX PT-17 motor lose power?
- M
  Melissa HowardAug 4, 2025
  If the motor loses power, it could be due to damage to the motor or power components; inspect these and replace as needed. Another cause could be that the nut on the prop shaft is too tight; in this case, loosen the prop shaft nut until the propeller shaft turns freely.

  Cameron PerezAug 8, 2025
  If a control surface isn't moving, check for damage to the control surface, control horn, linkage, or servo, and replace or repair any damaged parts, adjusting the controls afterward. Inspect wires and connections for damage or looseness, connecting or replacing as necessary. Ensure the flight battery is fully recharged. Also, make sure the control linkage moves freely.

What to do if Horizon Hobby Toy motor/ESC is not armed after landing?
- N
  nwallAug 13, 2025
  If the motor/ESC is not armed after landing, it's possible that the Over Current Protection (OCP) has stopped the motor because the transmitter throttle is set high and the propeller cannot turn. To resolve this, fully lower the throttle and throttle trim to arm the ESC.

What to do if Horizon Hobby UMX PT-17 motor power quickly decreases and increases?
- K
  Kimberly RogersAug 21, 2025
  If the motor power quickly decreases and increases and then the motor loses power, it is likely that the battery power is down to the point of receiver/ESC Low Voltage Cutoff (LVC). Recharge the flight battery or replace the battery if it is no longer performing well.

Why does Horizon Hobby UMX PT-17 Toy servo lock or freeze at full travel?
- J
  juareztiffanyAug 26, 2025
  If a servo locks or freezes at full travel, the travel adjust value might be set above 100%, overdriving the servo. Set the travel adjust to 100% or less, and/or set sub-trims to zero and adjust linkages mechanically.
