Yesterday I tried out some glue for the picooZ and I found out it dissolved foam, so I have decided not to use that After I found out I put it back together with rubber bands. The picooZ did however keep spinning so I don't think replacing the main rotor did help Something else must be the problem. I don't want to spend more money and effort in getting it flying again. It's not that fun flying compared to the Lama after all.
The best thing is the small size that means it won't break things easily when you crash. If I want a small heli again I'll get a Walkera 5#6 or similar. These small helis seem more gf friendly
