Hangar 9 P-51 PTS Trainer

This is a variant of the Miss America plane posted here.

It attempts to model the size and behaviour of the Hangar 9 PTS trainer.

I just got one of these and I wanted to have a G3 plane that mirrored it's performance before I flew it.

Physics dimensions, power handling, curves, etc. are modeled upon actual measurements for a stock P-51 PTS w/o the air brakes and wing droops.

Note, for accuracy please fly with the gear DOWN.

Flaps can be raised in flight with the knob.




Changes:

I've received feedback from people who have flown both my G3 version and the actual PTS.

The following model reflects those changes, and I believe is the most accurate representation of this plane to date.

The entire aircraft is available (EA), and the variant file if you already have the prior posts (AV), and additionally two other variants. One has a 3 blade 11x6 prop and the other a two blade 11x6 prop.

With this I consider this plane "done", except for the 3D model which I may fix later.

( I'd love to get those wing droops on as well as the PTS engine and air brakes...)

THANKS!!!!!!!!!!!!!!

Very nice plane. Let us know if the real one flies like that. I really like the feel of it in the air.

I'm still tweaking this a bit.

The physical dimensions, wing loading and power curves should be right at this point.

I may need to weaken the gear and fuselage a bit.

It's amazing how much flight characteristics information you can glean from people posting their experiences with the "maiden" flights of aircraft.

e.g. someone says that they cut the power to idle at 75 ft up, and this bent/broke a gear strut as the plane came down too hard.

I knew that my model's gear were too resilient.

Another post where someone stated that all the experienced fliers though that the pilot was coming in far too high and fast for a warbird. The pilot dropped to almost idle and everyone was amazed at how quickly it decellerated.

Since he gave figures, I can adjust until I get similiar performance once the basic dimensions are in place.

I think I have the stall correct given what everyone has posted...

".. a slight wing tip stall tendancy at full idle, up elevator, which is recoverable correctible w/o adding throttle."

This model does just that!

Videos let me see take off climb angles and give me an approximation of engine power settings that the pilot used.


Great stuff.

I'm unclear about one particular post (which may be abberrant) where the pilot said that he had to constantly give full left rudder at takeoff.

No one else has reported this, and everyone says it runs fairly true down the runway with only an easily correctible roll.... hmmm... just like this model.

I suspect that the poster didn't know about adjusting the throw angles on the radio...

Op:

You have to give it right aileron on takeoff with firewalled throttle, because of the overstated torque with .430. If not, you will takeoff on one wheel, and drag the left wingtip.

Not your problem!

Edit: Nevermind, the above is for a "tweaked" P-51 model...my bad.

I'm having trouble installing this one. In the zip file I downloaded, there are some "reno racer" files. I already have the reno racer and it's causing conflicts. Also, I do not see a .G3X file. I see a g3x.enc though, but the KEX file is titled reno racer.

Thanks in advance,

frank

Op:

I really like your flight model. I can confirm that it will torque-roll a turn or two, before it tail-slides very sloppily (hammering controls, to try to keep it straight!) through its smoke, and hitting the deck tail first. I like it!

The snaps are no problem at all (remember .410? That version taught snap recovery better than any sim I've tried!).

Flies very nicely, I'm able to mush it around some behind the power curve too!

I know...fly it scale.

Good work!

First post updated with new fixes.

I'm putting a ribbon on this and calling it done with the new uploads in the first message.

Feedback I've received from people that have flown the PTS indicate, that with the changes made, the G3 plane now behaves just like the real thing.
