Question about your Bumblebee. I just finished putting mine together and noticed that 3 motors appear to be tilted 2 or 3 degrees from level and the four appears to level. Is this normal ? It just doesn't look right. I am new to quads been flying Heli's for away and still trying to get my head around the concept of four motors flying in a box formation. Any help or insight would be appreciated. Your pictures are inspiring.
