A Retractable Pitts?
If you're a Pitts connoisseur, you might have seen this variation. A retractable gear Pitts? How does it fly? What advantages or disadvantages do retractable gear have over the fixed versions on most Pitts? Well, take a look at the photos and daydream about it a bit - we'll dig to the bottom of the Henry Haigh Retractable Gear Pitts and fill you in on all of the details in a future issue of Sport Aerobatics Magazine.

People cycle in and out of our sport of aerobatics. This can cause our institutional and collective memories to start dying with time. People leave the sport and take their knowledge with them, as most people stay in a hobby for about five to seven years, then move on to something else. Sometimes, life gets in the way. The way to combat this erosion is to regularly revisit hard lessons learned and to make sure that they get correctly reprocessed in our gray matter and passed on. These lessons must also get passed on correctly. Bad information can be as dangerous as no information. Read more

Picture of a Champion
Editor's NoteLast month, Reggie asked readers to identify who was flying what type of airplane in a photo posted in his editor's note. The pilot was none other than Cecilia Aragon flying her Sabre 320. Cecilia won a bronze medal at both the 1993 U.S. National Aerobatic Championships and the 1994 World Aerobatic Championships, and flew air shows for a number of years before moving on to other adventures. We'll be bugging her for a story in Sport Aerobatics Magazine in the coming months, so keep your eyes peeled. Here's a wonderful vintage video of Cecilia at the top of her game.

It's Dangerous
Hand propping an airplane may be seen as a nostalgic throwback to the days when airplanes had no electric systems, and by necessity, needed a hand getting started. Make no mistake about it - hand propping is extremely dangerous and should only be attempted after having competent instruction from someone qualified to teach you. Read more

Jim AlsipTeaching pilots to fly tailwheel (conventional gear) aircraft and teaching aerobatics are very similar. The pilot must have command of the airplane to do either one. Being in command includes controlling yaw and coordinating the use of rudder and ailerons together. The Dutch roll is a great coordination control exercise. This maneuver involves simply rocking the wings, right? It seems easy enough, but the Dutch roll can destroy your self-esteem. Read more

Some Airplanes Hate Crosswinds
Here's a video showing a valiant attempt by the pilot to keep the airplane from ground looping after landing in a pretty stiff crosswind in a WWI-era Fokker Dr.I triplane. He does scrape a wing, but the damage is minimal. Toward the end of the video, you'll see the original Oberursel Ur.II or Le Rhône rotary engine spinning along with the prop. That's right - the crankshaft was fixed to the fuselage while the engine spun around it! Watch the video

Radial vs. Rotary Engines Explained
Radial vs. Rotary Engines Explained
Both radial and rotary engines spin propellers, but the mechanical ballet inside each engine is quite distinctive. Each engine has cylinders arrayed in a circle and the pistons are attached at a center point. However once the engine starts, many of the parts are going in different directions. Watch the video

Reggie PaulkAnother month has passed us by and it's already time for the next edition of In the Loop! The feedback we've been receiving has been very positive, but I'd like to hear about what we can do to improve the publication. If you have ideas or suggestions, please feel free to e-mail me directly at

Last month, I asked you to identify the airplane and pilot in a photo posted to this newsletter. I received a lot of responses from people who knew Cecilia Aragon and were familiar with her airplane, but many of you gave good guesses. The airplane is a Sabre 320 with a Zivko Aeronautics wing in the days before the Edge 540. I'm going to bring you up to speed on Cecilia in a future issue of Sport Aerobatics. Read more
