Welcome to RCU. Perhaps a better forum for your question would be one of the "electric" forums RCU offers such as
http://www.rcuniverse.com/forum/forumid_123/tt.htm
or RCU's sister site dedicated to electric flight
www.wattflyer.com
Other than this we are more than happy to try to help you. Speaking only for myself, I know next to nothing about electric planes.
