While there are ways to improve the situation (direct drive or dual motors), there is no way the Blade and it's variants will have the tail control of a driven tail rotor.
I've just finished flying my modified HoneyBee CP2 and my HDX300.
The HoneyBee CP2 has the stock, geared motor driven tail. I now exclusively use the stock plastic tail rotor blades. I've had two crashes due to the inflight failure of the carbon fiber tail rotor blades. I no longer feel comfortable using them. This heli is equiped with an outrunner brushless motor. Changes in throttle/collective put varying demands upon the power system. This causes variations in the tail rotor speed that are not commanded. I keep the gain on the stock rate gyro turned down and just prefer to "fly" the tail. The fluctuations in the power system cause some slight yo-yoing.
The HDX300 uses a belt-driven tail. I'm currently using the 32-tooth main shaft pully. While tail control is "OK", I've just ordered the 40-tooth pully. I feel that the higher RPM tail rotor will raise the level of crispness to the tail control. The HDX300 is strongly stable in hover, with no hint of the yo-yoing that is typical of the Blade/HoneyBee and similar helis.
The HoneyBee CP2 is not flying on the stock rotor head. This heli is equiped with the MicroHeli rotor head/swashplate combination. These are very high quality components that offer stable and consistent flight characteristics.
The HDX300 is flying with the new V2 head. For want of a better description, this head is very close to being a miniature version of the T-Rex 450SE head.
Both Helis are equiped with E-Flite carbon fiber blades, flybars, flybar weights, and flybar paddles. In this configuration, the V2 head is extremely more responsive than the MicroHeli head.
My Blade CP has been retired. My HoneyBee CP2 is used as a backup to my T-Rex 450SE and HDX300. If you've not experienced or flown a driven tail, try one. They are definitely more accurate than a motorized tail. The down side is that they are more involved to set up. But they sure fly nice!
