Also using a longer flybar may also help.
Making the flybar longer makes the cyclic quicker, not slower. You can add weights and all that stuff and it will slow down the cyclic. The problem still remains that it is a small helicopter and is quite light. So I personally don't agree with y'alls assumptions.
Yes, using a longer flybar will indeed increase cyclic response. But the flybar is also a stabiliser bar that acts like a gyro when you are NOT giving it commands. Making it longer will give a longer moment arm for the stabilization (gyro) function to act. This was proven and explained by Curtis Youngblood (a world champion) many times at different events I attended. In fact you could tune your system to different wind conditions to optimize the stability by changing this length. If too short, the wind would make it drift downwind, too long and it would overcorrect and cause the heli to drift the other way.
