I have a Herr Little Extra with an OS .10LA on it right now, and love the performance, but only get seven minute flights.:( A bigger tank would require cutting the formers, which I do not want to do.:mad: I would like to go electric, but have no experience with it.:eek: My goal is to keep the same level of performance and increase flight time to around twenty minutes. What motor, ESC, and battery?:confused: Please help!:D

This is just to give you an idea of where you would be going cost wise. This would be a nice flying machine I'm sure.
Here is the site for the Himaxx motors. They have the other items listed and you can do a cost survey.
