Well what servo controller are you going to use? The reason i ask is i used the ssc32 board and the movements were choppy like stutery(is that even a word) and there is this fella on here that used a prop board from efx tek i dont know which board but his movements were super smooth! and the only thing different was the board so i assume that had to be 1 reason. One problem about efx tek boards though is you have to know how to program in basic....but i have heard that the people that work there will write the code for you if your nice enough and i think prop boards are stand alone. So i guess it depends on what your after and your budget. Hope this helps a little bit.
