Ybenjulkay,
How long will your heli hover before it drops? How much throttle do you input to get it back to the altitude from where it dropped? Did you mean that your headspeed remained the same when your heli drops or does the headspeed drop too?
Didn't make it the my LHS today, I'll try tomorrow. Meanwhile, I'm thinking about my next alternative. Maybe I didn't spray enough silicone on the tail drive belt, who knows.
