Hi everyone! I bought a 9053 Volitation Heli in Mumbai from Alpha at Irla. Failed to lift off the first time due to non-rotating lower blades. Closer look revealed that a screw above the upper gear had come loose in the first flight I attempted! Tried to tighten it, no go, completely free, I could see plastic threading coming off. So I put an over-sized screw, taking care it didn't touch any part of the frame, and it did the job. The lower blades were not slipping anymore. Tried to fly again. This time the heli got the lifting power and hovered for 2 seconds about 5 feet high and then came back to ground for an entirely different reason. The motor for the UPPER blades quit moving! I checked the motor's wires but couldn't find anything wrong and it hasn't started ever since. The on-board battery was at full charge, transmitter batteries were brand new. So I have yet to complete a single successful flight with this heli!
Now is it normal or just my luck that a brand new heli comes with slipping gears and defective motor? Could it be that the over-sized screw I used to tighten the hold of the lower blade shaft on the gear could have short-circuited something? I'm very new to RC flying and at a complete loss. Please help me!
P.S. I have attached pics of the screw I managed to fit above the upper gear.
