I am building a small model for Lambert Kolibri. In an attempt to make things simple I elected to use High Voltage rated servos on the flying controls (JR DS378HV) direct with 2s Lipo. A change of plan from hand-launch to fixed undercarriage means that I now need a steering servo. I am not too keen on spending $75 on a nose steering servo for this model.

Has anyone used 'normal' servos (such as Hitec 65MG) on 7.2V? If so, how long do they last?

Is there an easy (small/light) way to drop the voltage for the one servo? I have seen the Align step-down but this only drops 0.7v which I'm not sure would be enough.

Thanks
