Same here, incidentally where can I get replacement batteries please? Also have a “Picolo” heli with a bad feedback IC , supposedly this part can also be replaced on some units as its a soldered vertical board on the main.

I’m halfway there and grateful for the directions. But I’m not having any luck removing the broken plastic pins from the blade carriage. I’ve tried using a needle but no luck. Did anyone else come up against this?
