WARNING: Cancer and Reproductive Harm -


I got one in May. First flight it stopped working at 300ft agl then started to shake. After landing it showed -400ft. I sent it back strait away. In July I got a response that it had been received and was being sent off for warranty evaluation. It is now September and no word. Very disappointed as I have never had a problem with a Aircraft Spruce product in the past.
