Dancing Wings Spacewalker
 

Has anyone built the Dancing Wings Spacewalker (1200mm wingspan) kit? Looking for any advice or build logs that might assist me build one. I have just purchased a kit and am wondering whether to go electric or to go IC.
I have the servos, ESC and motor to go electric (but don't have the battery yet). I also have a brand new Saito 62-B sitting in a box that could be used.
Forgetting all the starting equipment fuel or batteries, I am also interested to know if this particular kit flies better with an IC engine or whether the electric version is a better flier.
Let me know your experiences of the build and any tips you might have.
