Assuming you mean a "standard" RC servo? You need to generate a 1 to 2ms pulse every 20ms for each servo. Most RC servos use 1.5ms as the centre position, 1ms for minimum position, and 2ms for max. Depending on the physical limits of the servo, you might be able to get enough angular movement of each arm to do something useful (aka like the Lynx5)
