Hi Stef, I am new in this KR world and I take every opportunity to read and learn from this family! However, I am just a bit curious about your solution for the "nose down" issue? Why would you want to install a fixed trimtab, instead of trying to resolve the problem through checking your "weight & balance" status, and possibly make some easy changes, such as moving your battery a few inches forward or backward...?
Kindly and stay safe & healthy! Dr. F.
