I have a MPI cobalt motor on my Electrajet, I have used this set up for over a year now and it rips!!! I have had no problems....it is a real work horse. I know that a brushless set up is more eficient, but this works.....when the brushes are low and worn....just change them. It is not rocket science. I do have brushless set ups in my other planes, but for now...this set up with the cobalt motor is working just fine. [link=http://www.maxxprod.com/mpi/mpi-26.html]Maxx Products[/link]
