TP,

Brushed motor power level control has very smooth start up and can often be turned down to a very slow rotation. One of the first brushless motors for R/C applications used sensors inside the motor to detect rotor position and send it to the brushless controller. This provided an incredible slow start up with predictable feel. When the brushless power systems lost their sensors to reduce cost and complexity as well as allow interchangability between manufacturers, they all started up with a slight jiggle to sense the rotor position based upon back EMF before starting up. Once started, the motor control works smoothly enough.

Julian,

Try pulling the videos from review which is now published on RC Universe at the link below. The Hitec Laser 4 radio system is top quality and could be used on any giant scale application without interference. The radio system will control the plane much farther than the eye can see it in the air.
