I took the ailerons down about 1/3 and took off the counterbalance area on the elevator. Because my primary pattern plane (Jupiter) is a 2 stroke (os1.40) I went 2 stroke on this one also (I'm using a Supertiger 90 with a Jett Stream muffler). I almost went with the YS 110, but non were available when I was making the decision. I've used the MK bellcrank on a couple of planes with good results. I moved up to advanced last year. I usually only hit a couple of contest a year. The shoot out in Muncie and the finals down in Cincinnati (Kentucky).
