She took a bath in the lake, pulled her apart and put her in 10# rice for 4 days. At first nothing but green lights, then she woke up but no gps. Called 3dr and said send it back finally spoke with a tech and he told me to check gps plug which I'm sure I did the first time. PHOENIX she has risen from the ashes. Don't know about warranty but I sent trouble ticket just in case. Gertrude flies again
