TJ's P51 gold course test - NON PARTCIPANT

Well guys, here is the last leg. Your pilot for this leg, who went over to a friends house and had a vodka tonic + 6 glasses of champagne...gets to fly an accusimmed P-51 with shoddy brakes to San Carlos...better get the firetrucks ready :icon_lol:


I LOVE ACCUSIM!...why is she climbing like a dog...gear and flap switches are up...well drunkey the clown forgot to close the hydraulic release valve before takeoff! amazing how much faster she climbs when the dangly things are up:icon29:
 
Ok boys, here are the numbers. Duenna played nice for this last leg here. Feel free to analyze the numbers.

I hope you guys can work her in to the RTW race and future SOH races. I did not push the P-51 during this trip thanks to accusim. I cruised at 43" 2500 RPM for all legs. A few of the legs I flew via navaids for the fun of it, and one leg I threw her around a bit to test duenna's response. As you can see, apart from worn brakes, the Merlin handled the course just fine since she wasn't pushed too hard.

Well Done!

Heya TJ,

Well done! I think this was an outstanding "experiment", particularly given the nature of Accusim with the accumulated wear and tear on the airframe.

I do have to laugh, though: those compression ratio values (yes, I have both versions of A2A Mustangs) are sooooo low (my 2V Ford 289 records 115 PSI). I guess the Rolls-Royce guys knew that high boost (60"!!!) would frag a high-compression engine, ergo the low compression ratio.

Again, well done. I want to retry portions of the Low Course with my RealAir Duke, but the Civilian Mustang would certainly be fun from Kalispel down to Jackson Hole!

Thanks JKH,

Yeah please go ahead and try the high course in the P-51, see if you get the same duenna errors that I did. The more data that we can get for Paul, Mike and everyone the better. Hopefully they can figure out some solutions for future events :). I think the flight tracking data is interesting. The P-51 is indeed faster, but her merlin is quite a thirsty engine.

Some of the folks at A2A have suggested this is in fact the fuel vapor returning to left tank, in essence 'refueling' the aircraft. I'll fly a few trips in the P-40 using duenna, which also simulates returned fuel to the Reserve tank. I'll see if this has similar issues.

Here is the A2A thread.
