| I dremeled the frame and it worked great. I now have a -13 to + 13 pitch range. I was at -3 to + 7 before I worked on it. The single biggest benefit was enlarging the frame holes for the A arm. There is so much pitch in the blades that I really think they will bend so far that they will snap. This little upgrade doubled the pitch range for me. I will post photos of before and after.
