Guys,
The real answer is the new "tuned electron pipe"! This is a magnetic tube with expansion section that will not only direct the messy electrons out the back and away from the ship but also provides superior wind performance by maintaining constant negative electron flow pressure on the motor subatomic magnetic flux structure. Another benefit, being a magnetic structure it is virtually invisible and can be mounted anyplace on the fuse without disrupting the look of the plane. The only negative is for anyone holding the ship if they are directly in back of the exit focus cone they could start glowing a slight shade of cobalt Blue. This is usually temporary but you may need to be defluxed or start a Las Vegas night club act.
This is going to change the way stunt is flown forever, no one will ever use anything else!!
Best, DennisT
