The Lucus Oil Pitts
     
 

The Lucus Oil Pitts was originally built by the Aviat Aircraft Factory in Afton Wyoming and finished in January of 1998. There were two other factory built Super Stinkers (Pitts S-1-11B's) built prior to this plane. Serial Number 4003 (The Lucus Oil Pitts) was the third and last factory built S-1-11B, and to this date the most modified, highest performance plane to fly out of the factory.

At the end of 1999 competition aerobatic season, I had just finished my second year of Sportsman Category and one regional contest in the Intermediate Category flying a 150 HP. S-1C Pitts. Just two ailerons, limited power, this Pitts lovingly referred to as "Little Orange" was a fantastic airplane that taught me the basics but was limited. I began looking for a plane that could eventually help me get through the Intermediate and Advanced and hopefully someday, on the U.S. Aerobatic Team.

I have always been flipped out over the S-2S and the S-1-11B design, so when Tom Kerns called to tell me he found a wrecked S-1-11B on Ebay, I knew that this plane was one that just might fit the bill. Tom wanted the wreck for the engine and a few parts and said that, "if I wanted", I could buy the airframe. The rest is history, Tom won the bid, we hooked up the four-place snowmobile trailer to the back of my Ford Explorer and drove to Texas to load up the wounded bird we dubbed "Princess".

The wings were removed and sent to Aviat Aircraft for a complete rebuild. I was originally going to tackle the wing rebuild myself, but I soon found that these wings were completely different then the original factory plans. Aviat had made too many changes to make way for four full span ailerons. This required some internal changes and strengthening which fortunately boosted the g-limitations to plus and minus 10.

As Tom and I disassembled the airframe, we took pictures of everything. Hoses, brackets, wiring, over 300 shots to help us remember how to put humpty back together again. Tom removed the 380 HP Lycon Engine, the damaged Hartzell Claw propeller, all the radios, CD player, several flight instruments and brake components for his own monster project. I was blessed with the airframe, and that's all I needed.

The plane had ended up on it's back in a ditch after the crash. The left main gear attach points were severely damaged and the vertical tail feathers were completely destroyed. We also found that both spars in the top wing had been broken. I enlisted the help of a good friend, a master welder and painter, the Jedi Master of rebuilds, Todd Sutton. After removing everything that could be removed, I gave Todd the airframe and let him do what he does best. A few months later, I picked up a masterpiece. The repairs were fantastic. He had also welded the tabs for the metal belly that I wanted. I then had the project bead blasted, primed and painted with ditzler dp-55 and began the slow process of cleaning parts, fabricating parts, repairing, painting and fabric. It was a complete ground up restoration. Prior to the crash, the airplane had a total flight time of 110 hours.
With new wings being built by the factory, and the airframe being put back together, it was time I started thinking about a power plant and propeller. I did my homework, asked lots of friends and then called Barrett Performance to order an AWAC qualified IO-540 parallel engine with the famous Barrett Performance cold air induction system and a six to one exhaust system. I also choose the new wide cord MT-Propeller and matching governor. I was able to eliminate the heavy oil accumulator mounted on the firewall that was needed for the Hartzell.
With the help, "with the undying help" of friends from IAC Chapter 78, Tom Kerns, Todd Sutton, Danny Hiner from Aviat Aircraft, Mike Niccum, Jeff Croy, Brandon McNeilus, Joe Wakely, Monty Barrett Jr., the Drometers, Kurt and the crew at Modern Avionics, (please forgive me if I have forgotten someone), I could not have had this plane finished without their help.
There were several memorable moments during this rebuild. Putting the new landing gear on the airframe, receiving the new wide core mt-propeller through customs at the International Airport. Pulling the cardboard cover off the top of the engine that Barrett built. Ripping open the huge boxes from Aviat that contained the freshly re-built, and covered through silver wings. Loading up parts to take home after Todd had painted them with that brilliant 1969 Corvette Hugger Orange polyurethane paint. Flipping the master switch on and watching smoke rise from the back of the dash (ooops,crossed wires). Strapping in for the first time and of course, starting the engine for the first time.
Two and one half years later, and more then 1200 hours of work, serial number 4003, the last of the three factory built S-1-11B's rolled out of the hanger and was ready for a second chance in life. From the moment I pushed the power forward on that Barrett IO-540, and found that I was airborne in less than four seconds, I realized one thing, my aerobatics from this point on, would never be the same.

Some interesting points to mention regarding this plane and the some of the changes made by the factory and a few made during the rebuild that are different than the earlier versions of the factory S-1-11B's. The Telex Pitts has four full span ailerons, approximately three bays wider on each wing. The rudder and elevator had been increased considerably in size, about 1/4 larger and squared off. I added an aluminum belly to help with inspections and quick maintenance. The 500-5 tires were replaced with 400-4's, and the same wheel fairings that were fitted for the Panzel Staudacher now dressed the Pitts. This reduced the drag area of the main tire area by at least 25 percent. A Garmin 250XL and matching transponder were installed along with the JPI instruments EDM 700 engine monitoring system, Unison's Slick Start, a complete B & C electrical system, starter, battery, a solenoid manual shut off switch and a digital fuel flow system for accurate fuel management.

The flying characteristics are wonderful. The wings were rigged with zero dihedral. That's great for aerobatics but makes for long cross countries. I have found no surprises with upright or inverted spins. Snap rolls are a twitch of the wrist and lots of rudder, timing is everything. Also, the stick pressure is fingertip, no more two-handed rolls or teeth gritting elevator pressure. I have found that this machine loves to torque roll and tumble all day long.
