It doesn't look right because it isn't a Culver..

That's some vertical stabiliser...must have knicked it from a B-17.

Radio antennae looking like a spindly nose gear strut missing a wheel?

Well done Bear.
dook - may we see the photo non-silhouette? - an interesting looking aircraft.

The Harlow photo is on wiki.
https://en.m.wikipedia.org/wiki/Harlow_PC-5

I think it is New bay in the background.

Now this 2D silhouette:

It looks positively twitchy...
Wouldn't like to stall it - even though it's a Trainer.
Round and round and round you go - having said that - with that rudder authority - you'd probably get out of Dodge in a trice.
Looks like it's related to the T-6 - when the designers came off the whole big tail trip.

If someone had thought up Uber Air Taxi in the 40's - this is what they would have depicted on the advertising garb;
"Arrive relaxed at your destination, in our fully equipped aircraft - ready to satisfy all your air traveller needs, etc..."

Nice. Any still flying anywhere?

Probably the same with the L......

I don't know if any Harlows are still airworthy. You can Google as well as I can.

Unfortunately I can no longer Google on the Internet.
I can only refresh pages that I have recently visited - including this one.

My PC appears to be - without my authority - to be self-isolating...

I believe there are some search engines who like to put themselves on top as standard opening page.

There are some PCJ-2s still flying.
Other PJC-2s That Still Exist

Also contains the story behind the ultra large fin.

I do not know much about B/A-ratio's.
I am just a deep sunken shipbuilder spinned out of his education.

Please elevate me (and others)

Not enough space here to go into pro/anti-spin characteristics and recovery.

I think the challenge is the Lockheed Alcor but I'm not sure exactly which model.

Further investigation indicates it is probably a DUO-4 or DUO-6.

Dook scores again!
the Alcor (Olympic) Duo.
This is clearly the Duo-6 as anyone can see due to the difference in air slots in the engine cowling!
remarkable engine set-up. Which forced me to only post a side view.

Just a curious question having observed, but not taken part in these threads over the last decade or so, who or what is "Heikkis' " ?? I've looked back, but there never seemed to be any posts with that name. Just curious tis all ;-)
