idk about the ember but i have the vapor and it will take ZERO wind. As in, you fly it in anything other than a big room with no a/c youre eff'd especially if its your first plane (idk if it is or not).

the ember looks a little beefier and might be a little more stable but i fly my vapor at my lhs and its a blast. i'd never fly it outside unless someone bet me and they'd replace the plane when i lost it. haha
