FTFC'25 WWII Fisher P-75 Eagle designed by Firestar119

[Firestar119]

While looking through Wikipedia's list of experimental WWII aircraft, I came across the P-75 of which only 14 were built.

(From Wikipedia) "The Fisher P-75 Eagle is an American fighter aircraft designed by the Fisher Body Division of General Motors. Development started in September 1942 in response to United States Army Air Forces requirement for a fighter possessing an extremely high rate of climb, using the most powerful liquid-cooled engine then available, the Allison V-3420. "

The design is still in progress, and the planned powerplant is the C Pack or an equivalent motor. Hopefully it will be able to hit 100mph when I'm done with it.

Hit 100mph? Now I’m watching this one!🤤😀😃

That looks great, it looks like you've been pretty busy!

I saw the last P-75A while I was at the Air Force Museum over the summer and got to thinking about R/C versions, but I didn't do much with it, so I'll be sure to watch and see what you come up with. Good luck in the challenge!

The first flying prototype is nearing completion
The C-pack might just have too much power for the size of this plane (around 30 in wingspan)

Sounds like it will be a rocket

 

[Firestar119]

The first prototype is complete, albeit with questionable build quality
I'm about to go test it today

 

[Firestar119]

The plane flies pretty nicely, but the battery decided to cut power right as I was pulling out of a turn, removing the nose as it landed" in the tall grass.
Time for a new battery.

Since my last post, I've decided to modify this plane's design style to make it much simpler to build and fit electronics into. The new design is closer to the classic FT box fuselages for simplicity.

Plans for the old and new designs are attached along with the stl files for the wing reinforcements

The plane is almost finished, I am taking it and my combat wing out to the field for a double maiden later today.

Great! It’s only you and @FlyerInStyle left, I had the thrust angle wrong on the Shinden, so RIP. (Wouldn’t climb with power, kept going down)

"Thrust angle? What's that?"

 

[Mr Man]

"Thrust angle? What's that?"

The thrust line corresponding to the wing chord line. It was pushing the nose down.

[Mr Man]

My thrust angle was the exact opposite to the one in the diagram, whoops.

that was a joke I didn't actually expect you to reply😅

You forgot to use the sarcasm font. So did I.

 

[Firestar119]

ready to fly

I kinda figured.🤣🤣. But I did it anyway. Plus if someone happens to come along this thread, now they know!😂

Too bad!

It flies very good, flight video incoming
