RE: Newbee has a couple of questions
I have to agree with a brushless setup. If memory serves me correct (which it seldom does), the Astro 05 was just your standard 27-turn brushed motor. I do not recall if it had a fixed endbell or not. If it is the fixed endbell variety; than it would make a far better paperweight than any type of propulsion system. Again, do not quote me on accuracy of the motor; but brushless / lipo's are the way to go.
