Today I added the Xtreme production heat sink to the main motor of the Walkera 4#3. It was a little loose so I bent it a little to make it fit tightly smiley

It seems there is always a problem with this little bird smiley Today I encountered several:
1: Battery tray broken – fixed with soldering iron
2: A main wing was tightened
3: A flybar paddle flew off during flight – Was recovered and put back on
Maybe the main motor is also due for replacement?

Anyway it really flew excellent after the main wing was tightened smiley
