DAC question

I am working on a project currently and have very little space to work with. My project is made to control the speed of my model rocket, and in order to do that I decided to either find a sutiable digital velocity sensor (which I'm having a lot of difficulties withskull.gif ) which would turn a servo or a propeller that spins a metal gear and then use·a hall affect sensor than use the DAC to change the analog signal into a digital signal. The only problem however is that I do not know whether the DAC will be able to work the servo!!! PLZ HELPconfused.gifshakehead.gifconfused.gifshakehead.gifconfused.gif

    Analog to digital is an ADC. How do you plan to control the rocket thrust? That seems where I would start since the electronics will all have to follow the hardware. Is this one of the Estes rockets or something bigger and why would you want to control the speed? I thought that was the whole object of quickly burning large amounts of propellent.
