Hi Grayone, welcome back to the hobby again. I started with a kinematic servo, very clever bit of mechanics.
The RC gear is so cheap in comparison though (for model boats) there is no need for complex mechanics.
You may have to ditch your RC helicopter radio in favour of the 40 Mhtz. or maybe you are on 2.4 Ghtz already?
Otherwise choose carefully and you should be re-using your servos.
regards Roy.
