Thanks 159th_Viper. Excellent videos - making it look so easy! I ran out of fuel trying to hook up in the A10 - could not get the speed constant - always accelerating to catch up or trying to slow down. Practice!! However, could you tell me the best way to set the tanker up? I have used the loop begin & end waypoints, but what does the refuelling mode do? What is the best speed & altitude for the tanker? Any help appreciated. Regards, ChrisD
