Bob, I got the tee-tail version of the Silent Dream 2.2, and ended up cutting a rudder for it. The adverse yaw at thermalling speeds could not be completely chased away with aileron differential, even at 100% mix, so I cut out a portion of the hollow fin, added a rudder post, built-up a rudder out of balsa, and installed it with EZ hinges. Added another microservo and music wire pushrod. Took maybe two hours tops, and the adverse yaw went away for good. I now use rudder-aileron mix and 50% differential. It turns on a dime, and you can rack it around from right to left to right again in less time than it takes to think of it. Maybe someone on the Exchange can explain how so many European hotliner designs can get away with no rudder, i.e., Graupner Cherry, etc. Don't they have a lot of adverse yaw at slower speeds? I don't like vee-tails, but if you do decide on one, you will not have to make a rudder like I did. You will, however, have to play with ruddervator mix to get rid of unwanted pitch with rudder input. BTW, you are going to love the SD. It's a real performer, and will permanently spoil you forever. You will never again be able to go back to balsa boxes with motors.

The wing is built-up, with a SD 7055 section. I have the option to get it with a Vee Tail or Tee Tail configuration. I've never flown a Vee Tail and was wondering if those with Vee Tail experience could enlighten me to the avantages/disavantages of the Vee Tail compared to the Tee Tail.
