Twister,

Engine pods gas or electric is really already done, all I need to do is make a duplicate power pod that has an e-motor speed control and lithium poly battery secured to it. You can see the design is interchangeable within 20 minutes.

Problem is I want 50 oz of thrust for an e verson, and the weight will probably be a draw other than the penalty of fuel. So other than cleanliness the e version has little to offer for a $300 power plant setup.
