If I remember correctly, with no input, a servo will sweep to one end of its travel, and if you connect it to +5 v will sweep to the other end. If that's all you need to pull the release lever, then just use the receiver output to your servo

As I said, to reach the limits, you DO NOT need PWM - I am assuming you only want your servo to be "all one way" or "all the other". Try it. If I'm wrong, you need a simple 555 circuit, if I'm right, you have all you need.
