Giant Scale Hanger 9 60cc P 51D DA 60 HD 8 21 16

The 8th & 9th test flights. The weather is severe clear, temperature 98 degrees F, humidity 95%, This is a test of this new plane and new engine to see if it can take the hot weather without problems. The video is a collection of the most visible footage of two flights. Footage at long distances too far away to see have been edited out. The model performed exceptionally well, no hint of high density alt. accelerated stalls. The new fully baffled DA 60, while tuned rich for break-in, showed no tendency to vapor lock when throttled back for slow flight. The JR XG14 radio had a solid link with the receivers and is an excellent radio. Flight control is by digital HITEC 5645MG servos and two Spektrum A7040 flap servos with aluminum after-market control horns. The engine's muffler is a cut down JTEC. The airframe has extremely good slow speed flying qualities and is very easy to take off and land. I let it get too slow for the second landing and it wobbled its wings just before touchdown. This would have crashed my TF GS P-51B, causing severe damage. Update- the DA 60 has broken in nicely, giving improved performance. The vertical climb is impressive, it takes 3 vertical rolls to slow it enough to roll out. Top speed is better than with the same plane with a DA 50r installed, weight is the same. The best prop is a Graupner 22-12 Pro carbon. 6-15-19 Update, After reaching its 40th flight, I went through it for a check of its airframe, and rebuilding the fuel system. I found structural cracks in the fuselage under the rear of the canopy. Applied glue to the cracks and inside the the fuse in the same area, continued flying. By the 45th flight the fuse crack traveled down to the wing fairing on the left, and started down on the right. An inspection of the wing showed the center section panel join cracking in the middle, and also at the leading edge in line with the fuselage sides. I have already lost two TopFlite P 51 ARF models to these same cracks. My first H9 P 51 D was damaged (repairable, but parts are too expensive) when a flap servo went hard over, soft crash landing in tall brush. I pulled this airframe out and did some destructive testing on the crack areas I had found in the second plane. It had the same cracks beginning in the same areas as the first plane. Since continued flight would result in loss of airframe and equipment, the necessary repair to return it to flight would be stripping the fuselage and wing center section covering off and fiberglassing these two parts. I was nearing completion of my Jerry Bates design P-51 B, so I retired the H9 Mustang until repairs could be made. Eventually I sold the cracked airframe to a club member who rebuilds damaged and crashed models after showing him the defects I had found. He plans to fiberglass skin the airframe for a strong repair. The Jerry Bates Mustang is almost identical in design to the H9 Mustang, although it HAS been around since before the H9 Mustang was released. Its plans-built airframe flies every bit as good as the H9 Mustang, and I reinforced the areas that had cracked in the TopFlite and H9 Mustangs. Its fuselage is a beautiful fiberglass molding by Vic Catalasan with scale outlines and panel lines molded into its surface. The wing is a sturdy design that I also glassed, the gross weight is under 27 pounds, less than the other two Mustang's flying weight. I bought a Varioprop 21.6 inch diameter propeller with the 2 blade hub, the DA 60 turns this propeller just as good as the Graupner 22-12 props I have used for years. I believe the DA 60 will turn the 4 blade version with little performance penalty. (I use the Hamilton Standard blade profile, which is scale for Mustang models). The best pitch angle so far has been 14 inches, giving a 2 1/2 turn vertical roll, and top speeds of over 122 mph level flight, Only a slight reduction from the same plane using the 22-12 props.
