I just dont get it? What the heck is all the fuss about. What is the big deal if David does some research and found data supporting the theory that the BC elevator servos are marginal (meaning if rigged exactly per manual their fine, move out one hole and you could be in trouble) and expresses his OPINION of this data he collected?? Had this data been posted by say....Bob Parks, would this information scrutinized so deeply?
In my opinion David's theory is correct, rigged perfectly the servos are adequate. For someone like me, where just adequate dosen't make me feel all warm an tingly, simply upgrade to higher torque servo!
I can tell you my BC was rigged exactly as per manual and I still had times where my elevator faded, not a pleasant feeling! I have since installed 2 DS8411's in my elevator and I have not had the elevator fade since, even though I have upped the motor from P-80 to P-120 and in much higher temps than when the fade was experienced. Does this support Davids theory? YES! Can I explain why many others have not experienced elevator fade using the 3301's, NO! But... I do know that my BC feels better and more responsive than before..... I also feel better mentally knowing I am over-kill rather than adequate....
I love BV product, he gets plenty of my hard earned money but I just dont get you guys..... he's just a manufacturer, no one is going to come and remove your right testicle should you decide to change a servo! Lighten up and take the data for what it is......OPINION
