Nice pics Siggi, keep them coming! I'm interested to see how that technique turns out, because one day way down the road I'll be playing with electric power and I'm going to need every lightening technique I can find. That one looks neat, keep us posted.

Hi Mike!
Well it is a problem if the plane is meant to handle both electric and IC power. If one makes a plane purely for electric power, it can be lightened a lot because it doesn´t need to cope with all the vibrations from the IC motor. The german E-Factor is an all-wood electric 2x2m plane that weighs in at 7.5 lbs! If you´re interested in seeing how it´s built, there is a build thread going here:

Really a beautiful design, but maybe a bit too fragile for my taste. But I just meant to show it as an example of what can be done with a pure electric construction. At least keeping one below 11 lbs should not be a problem.
