I got a question. I had my heli apart last night and I was checking the main motor (nothing hooked to it) and this is what I observed. At low speed it sounded like it had a "growl" in it and as I increased speed it would change from a "growl" to a higher pitched whine. I assume the whine would be normal and good but I am curious about the low speed growl. Based on your experience and what I have written, does it sound like the stock motor is going bad? Been flying on average 10 minutes a day for a month. Also, I don't know if it is related to the motor or if it is just the swash plate slop etc., but it seems that I am getting the Up/Down surges a little more often in a battery pack flight. The flybar is really loose on it and the servos (stock) seem tight under slight presssure.
Thanks in advance.
Heliko, still debating on priority of getting an upgraded TX or a HH Gyro. As you said earlier, need a higher channel radio to run the higher gyro if I plan to swap it to a bigger heli someday. My concern is if it will survive my flying until I get the bigger one.
