Doomsday, what the tail rotor is doing is totally normal for these types of helis. When it speeds up, it fights the torque of the helis main rotor forcing the nose of the heli to face right of its original position. When it slows down, the torque of the main rotor causes the nose of the heli to face left. The tail rotor in all helis is an anti-torque device. It, in combination with a gyro of some type, fights the spinning of the main rotor (called torque) so the heli can even fly at all. The reason your gasser changes the pitch is because its either belt driven or driven by a fiberglass tube in the tail boom. Either way, its driven by the main rotor's motor and it can't spin independently.
Yes I understand how the tail rotor works, I was just curious about these small helis, As I stated before, I had a gasser for a short time and just remember it being able to adjust the pitch on the tail rotor blades. It wasn't belt driven, It actually had two rods going through the tail boom and connected with z-bends onto the tail rotor.
I was unaware (at the time) that these small helis were a fixed pitch tail rotor so it kinda threw me off a bit. I gotta say these small helis are extremely twitchy. I am really shocked at how hard they are to hover. I am currently up to about 30 seconds at a time hovering mine in my kitchen now though. The ground effect is pretty rough when you only have a very small area to hover in. Two full length wall cabinets on two of the walls creates an interesting ground effect and keeps me on my toes hehe. I will say one thing though, these birds are tough as nails. I have crashed mine several times now (nothing more then 3-5 feet from the ground) and the only thing I have messed up was a small crack in the canopy.
I have also found that the aileron pedals and the rod do seem to bend very easily even a hard landing seems to knock them out of alignment very easy. Something I just got to get used to I guess. I have taken this thing outside one time so far and had it about 10 feet in the air for about a minute till a gust of wind came and forced me to land it as I am not yet ready to deal with that situation yet hehe.
I have been through 8 battery packs so far (would be more if the wife would stay out of the kitchen hehe). i have noticed some glitching in the tail rotor on occasion, sometimes you can hear the servo and the tail will swing over to the right. I believe it may be caused when I get the heli directly in front of me with the transmitter antenna pointing straight at it. I remember my airplanes glitching when that situation came up, so I am not worried yet. Wont know if its an actual glitch till I can get it outside and run it for a while in a more open space.
