January XP-82 Twin Mustang Restoration Project Update

We have been very busy this month starting to complete hundreds of small to-do tasks that had to be finished, i.e., gun sight, completing the 90 degree periscope on the gun strike camera, making heat and defrost, repairing or remaking electrical switch panels, bomb arming panels, fairings that surround the throttle quadrants, a second mounting panel for the oxygen quantity gauge, blinker and diluter valve mechanism, two induction trunk carburetor filtered air boxes, one last 28-volt power supply harness going to the breaker panel, preliminary locating and shielded wiring of the microphone and headset jacks, modifying the shelf underneath the oxygen diluter mechanism to fit the new Garmin radio package, along with the avionic electrical harnesses, etc., etc., etc.

All of these panels, which we had to repair or make new, have been shipped off to our screen printer for him to silk screen all the correct verbage on each panel.

Garmin Radio Package
Our avionics specialist came to Douglas with the Garmin radio mounting tray and fit it into the pilot’s righthand cockpit underneath the oxygen diluter panel. With a small modification of one rib, it fit in perfectly. The microphone and headset jacks will mount in the original locations in the adjoining switch panel to the left of the Bendix Radio panel. And, in the co-pilot’s cockpit, they will mount in the original radio switch panel with the addition of drilling one hole for the headphone jack. 

Bendix Remote Control Unit
With much searching Weezie was finally able to find this Bendix Remote Control Unit from a collector in California. An extremely rare unit, the last time we saw one change hands was back in 2006.  We were able to purchase this unit only if it was going to be installed in our XP-82.  Thank you.

Filtered Air Boxes
The last major thing being done on the firewall forwards is the manufacturing of these two filtered air boxes. The rotating carb air valves located under the spinners have four selectable positions:  ram air, hot air, half-hot air and filtered air. These are two complicated boxes with many angles and shapes that hold the filters for filtered air.  It will still take two team members about two weeks to complete and fit both.

Internal Press Dies for the Main Gear Door Skins
Our machinist from Michigan has completed these two huge (350 lbs. each) mirror image press dies and personally delivered them to us on his trip to Florida. I did not want to trust these to UPS or FED EX. These were very expensive to 3D design and machine, not counting the cost of the two 40” square x 3”thick aluminum plates. These press dies will be taken to Atlanta to press-form the skins as our rubber press is not large enough on exterior dimensions. 

The torch is there to give a reference to the size of each door press die

December XP-82 Twin Mustang Restoration Update

Merry Christmas & Happy New Year!  
Another month has gone by so fast.

Much time has been spent on the final fitting of the rotating carburetor air temperature mechanisms, along with the air intake lips and the four side panels.

As mentioned last month, all of the lower and side engine cowling panels are now completed. The final shrinking/stretching, English wheeling and Yoder hammer forming of the top two right-hand engine cowlings will be completed in the month of January. The left-hand top panel for the right-hand engine is now final formed and fit. The right-hand top panel still needs a little more stretching and wheeling. 

The six oxygen bottles are now fit in each fuselage along with all of the fill feed tubing and one-way check valves. The fitting of the two O2 Blinker gauges, along with the Oxygen Diluters is being accomplished. Below this O2 Diluter shelf is where we are planning to hide the complex Garmin avionics package to maintain originality.

Trying to find the original routing of the O2 tubing was a challenge as all of the plans that we have show extremely stylized drawings which contradict similar drawings on the following pages. We were able to locate the original drilled holes in some of the rejected side ribs, allowing us to be able to determine the location of the original line clamps. They were in dramatically different locations than the stylized drawings. We also were able to find the NOS four-way Schrader check valves to install to maintain the authenticity of the O2 systems.

The mounting of the gun sight in the left-hand cockpit and the gun strike camera in the right-hand cockpit is proceeding, I hate to say, slowly. Trying to put everything back into this XP-82 identically as it was on day of its first flight, 15 April 45, is excruciatingly time consuming.

Gear Doors
The preliminary forming dies for the main gear center section doors are now complete. The internal pressed skin for each door is a mirror image of the other side. Many hours of machine shop computer work went into these press die patterns.  These two center section gear doors are two of the last four major items to complete on our XP-82 restoration.

Control Surfaces
The final balancing of all the control surfaces, i.e., four ailerons, two rudders and one elevator, is now complete. (Aircraft control surfaces must be precisely balanced [in accordance with the XP-82 Erection & Maintenance Manual] equal weight forward and aft of the centerline of the hinge points.) If they are not balanced, they will flutter in flight as a flag does in a heavy wind on a flagpole. We had to add some additional leading edge weights to each surface because we replaced all of the hinges, trim tab fittings and trailing edge strips with a much stronger and heavier weight 7075 T6 aluminum in place of the original lighter weight cast magnesium fittings and strips. Trim tab fitting failures during high speed flight have been known to be fatal.

Counter weights installed on the leading edge of the ailerons

Wing Tips
Three of the four wing tip formed skins are now completed with the fourth being completed this week. When completed, each half will be TIG welded (tungsten inert gas) by our professional welder in Florida. He will match exactly the TIG welding bead pattern done on the original wing tips.

November XP-82 Twin Mustang Restoration Update

 Happy Thanksgiving to All.

We are all moved in to our new hangar.

Firewall Forwards
The last left-hand engine upper, lower and side cowling items have been completed. The final installation of the left-hand propeller has been completed with the exception of the spinner. We will leave the spinner off during the test runs to check for leaks.

The final mounting of the right-hand propeller should be completed by the time you are reading this newsletter.

The induction-trunk lower intakes for the right-hand and left-hand engines have now been completed and are being final fit awaiting final sanding and polishing.  These were very difficult forming tasks. The rotating carb air temperature barrel mechanisms and mounting structure are now also fit, but removed for final painting.

The mounting installation of both heat exchangers (oil/inter coolers) is now complete. They both presented a problem as they interfered with the upper cowling arch framework. We had the original exchanger mounting straps attached to the dishpans, but we did not have the original rings that mounted the exchangers to the straps. When we machined the rings as per the XP plans, the exchangers would mount about an inch higher and not nestle into the two factory-formed notches in the oil tanks. After redesigning and machining the four new mounting rings, the interference problem was solved. 

The test running of both engines, and all of the associated systems, will start in December. 

Outboard Wings
The English wheel forming of the two wing tips is progressing rapidly. Both wing tip upper panels are now completed and the two lowers are in production to be completed sometime in mid December. 

Landing Gear/Doors
The subcontract machine work for the press dies for the inboard gear doors is progressing nicely. The outboard door skins have been completed for some time now awaiting the completion of both interior frameworks. 

Tail Wheel Steering
Both tail wheel steering mechanisms are now final installed less tensioning. A number of moving parts required to move two tail wheels left and right.

The machine shop is currently 3-D computerizing both brake calipers. These brake assemblies fit only the XP-82 and following production models. They are an unique anti-skid design and, through reports from pilots, worked extremely well.

Authentic Interior Cockpit Furnishings
We are heavy into completing the internal parts in each cockpit, i.e., gun site, gun camera, oxygen regulators, gauges and blinkers, original radio heads, heater and defrost controls, exterior ADF ring antennae, etc., etc.

VIP Visitor
We had the honor of a visit from Col. Robert Thacker, 98 years young. He was the pilot flying P-82 B “Betty Jo” on the 1947 14.5 hour non-stop flight from Hawaii to LaGuardia airport in New York. One cannot believe how sharp and alert he is at the age of 98. He still knows every detail that went into the preparation, the test flights, the additional fuel tanks installed inside the fuselages and the exterior drop tanks and why three of the four drop tanks could not be jettisoned. (The sway braces were wrenched down too tight by a ground crewman not allowing the release hooks to drop the tanks.) One of the tanks did drop leaving the other three under the wings creating a dramatic yaw condition requiring a substantial amount of rudder trim drag.

He described in detail the additional 150-gallon fuel tanks installed behind each pilot seat and the 60-gallon tank installed in the gun bay. He even distinctly remembered a plug being inadvertently left in the gun bay tank vent line during one of the test flights, resulting in the tank collapsing and a replacement having to be manufactured.   

The P-82 had a total of 1,860 gallons of fuel at lift off, including the 600 gallons of production center section and wing tanks, two 300 gallon and two 150 gallon wing drop tanks, and the 360 gallons of additional internal tanks added for the long flight. 

Total distance Hawaii to New York - 4,899 statute miles. 14.5 hours total flight time. Average cruise speed - 338 miles per hour. Taking tail winds into consideration, that’s 300+ mph cruise.

I hope my memory of the details he told me during his visit three weeks ago is as good as his memory at 98 years young. 

Concorde Battery
A special thanks to Mr. Don Grunke of Concorde Battery Corporation. Concorde contributed a brand new battery for our XP-82 project. 

The quality of their batteries is outstanding. As I have mentioned in the past, one of his Concorde’s lasted nine years in my B-25 Mitchell. 

Thank you Mr. Grunke and Concorde.

The Kat
With who just got elected, you are not going to be able to sleep on the job anymore.

Being Thanksgiving, it is time to thank all of the people and companies that made this project a success.  Thank you all.

October XP-82 Twin Mustang Restoration Update

Hello Everyone.

What a month October has been. 

The entire crew worked an incredible number of hours to get our XP-82 moved into its temporary new home. 

The first thing we did when it arrived in the large hangar, was to install both propellers and then complete the last few items required for the initial engine starts. I chose to have Jose Flores, the manager and now new owner of Vintage V12s, to come and start (his) engines for the first time. Vintage V12s now does 80% of all the Merlin engine overhauls done worldwide. His customers’ Reno race engines have won the Reno Air Races nine years in a row. That’s like winning the Indianapolis or Daytona 500 nine years in a row.  Beyond impossible. When I ordered our engines, his record was at five years in a row. This is why I chose Vintage V12s to do our engines.

The next thing we did was to partially fill both inboard fuel tanks and put Glycol in the coolant system for each engine to check for leaks. The fuel cells were perfect, but we had a few minor weeps in the coolant line attachments, which have now been corrected. 

The third item was to temporarily attach the outboard wings. We still have to complete the aileron trim and the fuel feed hoses.

Prior to starting the engines, we purged the fuel and oil systems, pre-oiled and then test started both engines on the afternoon of 14 October and idled them at 500 rpm for a short amount of time. We discovered a problem with the propeller governors, thus we could not get the propellers out of feather position (cage) to apply any type of power or rpm to either engine. The only systems we had online for the first engine starts were oil and fuel pressures, Gycol temps and tachs.

 leading edge cowlings

We will be test running the engines on a regular basis, proving more and more systems during each run.

The final items that need to be done prior to the first flight will be to complete the hydraulic system, brakes, gear doors, retractions, top cowls, wing tips, fairings, and wiring for the all the Cannon plugs in the original WWII radio package in each fuselage for authenticity and wiring the hidden Garmin package for reality.

The Kat
Allison is going through withdrawal realizing that we are not in our original hangar anymore.

We have had many people contribute parts to our XP-82 restoration, but the two people who have supported us from the beginning with a massive amount of contributed parts are Larry Kelley, B-25 Panchito, and Michael Ryan, Aircraft Stock. Both have contributed literally tens of thousands of dollars of new old stock surplus parts; i.e., liquidometers, relays, special instruments, authentic cockpit parts, mixture motors, fittings, switches, pumps, etc., etc. Thank you, Larry and Michael. Without your help, it would have taken many years longer to find all of these parts.  Thank you, all!

Finally and most importantly, to our invaluable volunteers and team members -- Thank you for your hard work and dedication to our XP-82. Whatever the task, you always found a way to get it done. Thank you for all your extra effort ... our XP-82 Twin Mustang wouldn’t be where it is today without you.

Thank you all for being such an important part of this restoration. We could not have done it without all of your support. 

Tom and the XP-82 Team
