This week in Aerolab, teams came together to attach their separately assigned parts to the RV7, marking our overall progress.

Another team was match-drilling the door handles on the outer frame, while the other is seen adding stiffeners to the RV7 rudder. The final team was countersinking the rollbar, which is the frame for the RV7 and where the plexiglass will be placed.

Nov 02, 2022     Working on the airplane! - (3 hours)       Category: Fuselage
Coolest day of the class (in my opinion). We had a little field trip to the cable airport to see the cute yellow airplane. Many of us got to sit in it and took pictures. Then, prof Harris took off on it and went 150mph (I think) in a low pass to a rapid ascend. It was super cool and everyone was amazed. Then we came back and continued building the airplane.

Sep 21, 2022     Progress Journal 09/21/33 - (3 hours)       Category: Empennage
Our little Mudd bees are at work during our first full work class. In the first picture, we have a team working on the rib of the mid-fuselage. In the second picture, we have another team working on the lower fuselage. Here the worker bees are in action riveting lots of nut plates. Next, we have the most important bees at work. They are creating the seat back and ensuring that the pilot gets the proper lumbar support they deserve. Lastly, we have a team working on riveting the primary structure. It is a very exciting day to be a worker bee at Mudd!
