I've had mine for just a little over a year(2nd batch) and I'm just now getting it dailed in where I like it. The plane has been fun to fly sport with but 3D'in it was a bit puckering to say the least at times, it would start rocking and scare the crap out of of me so I would just stop trying.

I've finally figured it out though. first of all NEVER assume that the plane will build with the correct incidences out of the box, they never do. With the airfoiled tail being as effective as it is there is zero tolerance of mis-alignments, trust me on this. My edge had enough play in the stab mounting holes that I could vary the incidence by + or - 2 degrees on the right side and about a degree on the left. You HAVE to use a meter to get this right or you will be chasing your tail.

Lateral balance is the second issue to be addressed and should be checked by supporting the model, hatch off, dead center by a cord. You can make a fixture that will slip between the motor box sides in the lazer cut holes.

While both of those steps really can help they pale compared to the last step that has been to date the hardest for me to get right but each time I tweak it the plane flies better. GET THE ELEVATOR HALVES TO MATCH PERFECTLY though the whole trave from 50 degrees up to 50 degrees down. I can't say this enough, you CAN NOT eyeball this so don't even try. Get a couple of clothes pins and a length of .070 carbon fiber rod. The CF comes in 24" lengths so you can cut it in half and glue the rods to the clothes pins. Clip these pointers on the elevators and bring the tips of the rods close together behind the rudder. Now turn on the radio and the plane and test the set up, chances are you'll find that they don't match each other, especially at the extreme limits of throw. Getting these two halves synced together can be a real pain in the backside but it WILL kill the rocking everyone keeps experiencing. I've used this technique on 3 other planes that had rocking problems and it has solved the problem on all of them.
