So, I just took my Spark out for an actual flight last night with 4.2.12  (coming from 4.1.15) I got out about 1900 feet and lost connection, I  have went the same exact route as last night, and was able to get out to  3000+ feet, also at the time I lost connection, I got a "High wind  velocity" warning could that have anything to do with the lost  connection?                                                

Hi, there. I would recommend you enter the wifi setting and check if most channels are green before flight. Please fly in recommended environment and ensure that your antenna is in the right position. Thanks for your support.
