Logan,

Although I have seen modifications on the larger Ultimates, I have not seen a need for them on this plane. The rudder is already much lasrger than it actually needs to be; if you like the look, I see no problem with counterbalancing.... I have seen no reason to think she needs it. I also thought about the 2 servo question (in the wings) until I flew a friends; once again, it is a weight addition without a true need. With all four ailerons connected, 1 Hitec HB475 servo as indicated on the plans has worked well. The beauty of this plane is partly due to its size and wing.... it is a great flyer if built stock and nicely powered. The only problem I see with the 70 is not ulimited vertical; but I flip this think around so much, I usually don't fly straight up very long.... a friend suggested the Saioto82 for that but I don't think it would enhance the fun I have with it now. Take care when you fit the upper wing; if you get it right the first time, it is a great way to setup a bipe... I use locknuts that I replace every other month to hold it down nice and tight.

No problem with the questions, that what is great about RCU.
