Dear GAUI customers.

GAUI X4 II was very well received in the RC helicopter market,
with its in-flight tracking accuracy, power attributes and the overall design characteristics.

However, during our continuous long term flight testing,
we have discovered a small weakness with regards to a part located in the side main frames.
In a situation where the helicopter is crashed, pressure is placed on one location in the side frames which has the tendency to break.

GAUI being a responsible manufacturer has improved and modified some parts to increase the rigidity of the main frames.

We ask that current customers of X4 II should contact their original place of purchase for exchange of their X4 II original parts
with the newly released upgraded parts (see attached photos).

Please accept our apology for any inconvenience this may cause.

However, please understand that these parts will reach our distributors at different times due to varying shipping conditions.

The exact time of exchange for upgraded parts should be based on information provided by your local Distributor or Dealer (your original place of purchase).

While you are still able to fly your X4 II in the meantime, please be mindful that should the model be crashed,
the likelihood of damage to the side frames is increased until the updated parts are installed.

Your truly,

GAUI Team

Original X4 II part (see attached photo) you should remove from your X4 II and send back to your original place of purchase
