Theres no doubt this is legal, it just brings sanity into question in regards to the builder.

I made the rudder pretty good sized.

My biggest concern is a hard left roll when I make that first full elevator turn.. I was thinking about how I would test fly it, and it will be a gradual takeoff from idle to see how hard it pulls left on the ground to decide how much rudder I need for flight #2. Once airborne, instead of making a standard left turn I will get some altitude and make an immelman turn to see the effects of the elevator pull. The viper Ailerons are pretty small, but I set them up for max throw to try and control this thing after I know what its going to do. I still think there is also going to be some sort of yaw issue with elevator, but I think the roll will be worse.

I just hope to get a few flights in it to try and mix it out before the locals start digging through the trash can. First flight won't be much more than 1/2 throttle, unless its flyable.

All in good fun, now I gotta finish the rest of 2008's fleet.
