I am working on a robotics project for my Masters Thesis and am designing a robot that will fly (kind of like a helicopter) but can also power other systems with the second shaft of a dual shafted motor. The secondary system is essentially a linear actuator and will be engaged and disengaged with a clutch. No motors I've found have the power to weight ratio that the motors specifically designed for RC airplanes have. Most of the controllers use back emf to control commutation, but from what I've read, it is not effective at the relatively low RPMs I will be driving the actuator at.
Is there any way I could assemble a hall effect sensor assembly to one of these motors, and combine it with a servo driver to make a servomotor?
Here is an example of one of the motors I've been looking at:

Here is the hall effect assembly I'd like to assemble to it

And finally, this is the drive I have been looking at integrating into the robot's controls

For the prototype, I'm not looking for ultra precision out of the actuator, just enough to move back and forth between the stroke limits at decent velocities. I don't have a lot of experience with this sort of stuff, and had a few questions. Are there characteristics of the above motor that won't let it work in the proposed system (ie number of poles)? Do I need an encoder, or will halls work? Is there a different drive I should be looking at?
I don't have a huge budget and would hate to buy the components and not have it work. I'd really appreciate any feedback you can provide.
Thank you for your help!!
