My build has officially begun. Even before I can complete the very first step of constructing the empennage, I had to enlarge mounting holes to accommodate M4 rivnut – blind fasteners. The process went well and I’m very glad to be underway.

 

 

 

I’m waiting for a #19 straight chucking reamer to arrive on Tuesday. Then I can enlarge screw clearance holes corresponding to the rivnuts.
