I look at it as 3 main parts and don't want to advise as I get in trouble. BUT you have a battery, 2 motors, 4 in 1 unit. I thought the battery but the 3 I had were all doing basically the same thing from 1.5 to 6 minutes of flight time. I changed the 2 motors as they say they have a life of about 20 hours flying time NG. The worst is the bigger money item the $59.00 4 in 1. After talking with a total of 7 techs from e-flite some things started to come together. One tech kept asking "Now whats the problem again" next time "so it won't fly" next time "So the battery is dead" next "so you can't get it to fly". WOW! Seemed like something from the late 60"s. A FEW TECHS HIT ON THE 4 IN ONE SO THATS THE WAY TO GO. Most of us spend tooooo much money anyway on junk try a 4 in 1. Hope this helps! Ron
