The reason that the torque question came up was due in fact to servo selection. I see no problem with where this thread has gone. Half of all of the posting going on in RCU is subjective and only scratches the surface of the subject. That is what makes it a forum. If the original poster wants to broaden the scope of the thread to answer what is behind the original question, I see no problem in it happening. That is why RCU is great!

Imagine a forum where the handling of a car was discussed. We wouldn't be able to talk about tires, because selection is subjective and there are many brands and types out there. We would have to start a seperate tire thread to discuss how tires affect handling. Sorry, just another bad example.

The only problem I see is that the thread may be in the wrong forum, but I see a parallel because it is aerodynamic forces that play a roll in what the thread is discussing. It would be great if some of the people flying the bigger birds would chime in and give the original poster some more insight on what was behind his original question.
