500 size Chinese Tail Weight Mod:
The tail servo is under much more strain while the tail blades are spinning than you realize.
When
the tail blades are not spinning, there is very little load on the tail
servo. But when it is spinning, the tail slider wants to forcibly move
to center due to something called the "tennis racquet effect".
This makes servo movement to the extremes cause ALOT of force on
the tail servo. Tail servos need to be fast to compensate for forces on
the helicopter that want to spin the tail. Faster tail servos hold the
tail better. But tail servos when loaded against more force will move
slower. Many manufacturers are adding this standard to their helis (MSH
Protos, Align 450 Pro Align 450 Sport, Align 250SE, Miniature Aircraft
Furion, SJM 430
Coupled with a digital tail servo, I have been able to increase my gyro gain by using this mod.
How
much depends on the existing weight of your tail blades and the
strength of the servo. Weaker servos benifit more than stronger servos.

So your parts list is:
qty 2 3mm by 20mm long socket cap head screw
qty 2 3mm nylon insert nut
qty 14 3mm flat washers
You can get fastiners from http://www.rtlfasteners.com

CM3020 (#3 3mm x 20mm SS hex cap screw x 12)
ML030 (#3 nylon insert nut x 12)

This is enough to do 3 500 sized helis. Add more MF030 washers to do more helis.
