Horizon recently announced the recall of the charger and power supply from the Hobbyzone Super Cub S RTF and BNF. Apparently, there is a possibility that the combo could damage products and/or start fires. The effected items are only found in the Super Cub and not any other airplane by Hobbyzone or Parkzone.
If you own a Super Cub S (the version with SAFE technology), please stop using the charger and power supply, go here and fill out the form, and wait for Horizon to send you an email containing a pre-paid shipping label. Please do not bring the items back to the store, as we cannot replace the items for you.
For more information, please see Horizon's offical statement: Product Recall: 3S Li-Po DC Balance Charger and Power Supply.
