RE: A-10 thunderbolt /Gaunli
That plane uses a brushed motor with a LiPo battery.
For longevity you want to break in the brushes.
Charge the battery and run the motor at about 50% until the battery runs to cut-off.
Repeat.
Then do it again, incrementing the throttle about 15% for each run until you get to 100% ( however only run the plane at 90-100% for less than 30 seconds at a time on the ground... ).
This should wear the brushes in approprately.
Remember to get it trimmed out by an experienced flyer.
