Ron's RV7 Aircraft Factory


Welcome to my personal blog. This site was created as an informal description of my build progress in the construction of a Van's RV7 aircraft. A place where family/friends/builders/curiosity seekers can follow along. It is not intended to be a detailed description of every step in the building process as that would be much too time consuming. There are plenty of sites that do a great job in that arena, that is not my intention with this site. My intention is for this to be a philisophical/motivational/inspirational account of the emotional ups and downs of the life changing journey...and it will change your life. I hope this will give you an idea, through my eyes, of what its like to make this transformation. A note to other builders, I am not an expert so do not put your safety at risk by attempting anything you see on this site until you have done your own research, or send me an email so we can discuss it. Any deviations from the plans are not approved, nor endorsed by Van's Aircraft or myself. Thanks for visiting.

Elevator Travel HOBBS 182.0 hrs

One of the things that needs to be done on the empennage is trimming the rear spar for elevator clearance. The control arms on the elevators (not shown) will contact the rear spar flange and limit its travel. So, part of the flange needs to be trimmed back, as you can see in these pics. Of course, we never want sharp corners, so a nice radius was added to eliminate stress concentrations. I didnt see a note in the plans to do this, but it is just good practice to always follow this rule. The vibration caused while in flight will wreak havoc on stress concentations, causing cracks. I also did my typical edge cleanup with scotchbrite.
