They told me that some of these plane have a bad circut board.
I have to send it back to them with a note saying what is wrong and they will fix it or replace it (most likely replace). The rep told me to keep the flight battery to defray the cost of shipping to them. (Shipping back is on them).

Here is the contact information for them.
