[QUOTE="Northwood Mediaworks, post: 97735, member: 6411"] Hi... the Spark uses a combination of the IMU, Compass and GPS to figure out its position, speed, etc. A sudden gust of wind can affect your IMU (think accelerometer) and cause it to become out of sync with the GPS and compass, if it's significant enough, the aircraft will switch to ATTI, and then you must manually control the position of the spark, otherwise the winds will take it to wherever they want. (hence the idea of a fly away...). If you have line of site of your craft, you can pilot the drone back to you with the remote control and land it. Sometimes once the wind settles you may regain a GPS lock. Simply having a bunch of satelites is not a guarantee that you will maintain position. Hope this helps. By checking the wind profile in the area where you plan to fly in advance, you have the best chance of a safe and happy flight. On windier days, best not to go up to 120m/400 feet. Flying low to the ground is a way to get out there and fly without that particular risk. Just watch out for trees and buildings! [/QUOTE]
