i've noticed that I had a vibration problem when there was some space between the chassis and the maingear and the mainshaft was a little bit loose.. so i pushed the maingear up to the chassis and put in the screw from the maingear. I use a carbon shaft for this.

and most drifting issues can be solved by adjusting the length of the servo linkages.

this also fixed a xk k100  which wasnt able to lift off..on full throttle the rotor was only spinning but the k100 didnt take off.. so I adjusted the length of the linkages and the k100 was fixed..
