Since converting a giant-scale plane to electric is a costly endeavor, please do some research before you decide to buy a power system. You can start your learning process by reading my article called, [link=http://www.gregcovey.com/Glow_Conversions_Made_Easy.htm]Glow Conversions Made Easy[/link].

We saw some new 10hp and 15hp electric inrunners at the WRAM show last weekend. These may provide a better choice and lower cost for your project. The shop called [link=http://www.finedesignrc.com/default.htm]Fine Design RC[/link] does not appear to have them on their Web site yet so I have queried them for information.

Good luck and welcome to clean and quiet electric flight!
