Got some 1/2 " aluminum to make a spacer for the pitch servo. Drilled a .225 hole then reamed to .25. Installed spacer . While checking travel I felt a bind . I discovered I had the bellcrank backwards and the lock nut on the rod end was hitting the bellcrank. I reversed the bellcrank and everything worked smooth. The servo stops are built into the bracket I made but the forward stop allowed the arm to go just a tad further than I liked so I installed a forward stop. I didn't have an AN4-24 bolt so I used a -30 with some washers until I get the correct bolt.
