A place for your North American T-28 Trojan Ideas and Inspiration:

To begin with, what about a twin engined version: This was a real proposal to convert some T-28s into twin engined strike and close-support aircraft by Volpar with two Garrett TPE 331-3U turboprops of 904 hp each:

Could be interesting to attempt to model.
-
The perspective view looks kinda cool, but the profile is UGLY! Doesn't mean it wouldn't be a cool project, though. A bigger nacelle would sure LOOK better.
-
Export version with Astazous in place of the Garretts? I could see using the nacelles from a Pucara.
-
In light of the the Pucará mention, how about an Argentine T-28 modification programme? ...
By the time that the first FMA IA 58 was delivered to the FAA in early 1976, the T-28Ps of the Comando de Aviación Naval Argentina were wearing out. Replacing these ex-French 'Pepín Cascarón' ('Humpty Dumpty') couldn't wait for a naval Pucará.
In 1977, selected COAN 'Taco-28' airframes were refurbished and fitted with twin 562 shp Astazou II turboprops. The refurbished aircraft were dubbed the T-28T Chilla (Grey Fox) but, invariably, they became known as the 'Turbo-Cascarón' (or 'Turbo-Egg').
Shown is a T-28T of 3° Escuadrilla de Caza y Ataque, COAN, April 1982 ... with apologies to Tom Cooper ;)

Oh, I like that; it looks quite purposeful. Odd thought: single-seat version with F-51D/K canopy?
-
Well done. :)
-
The twin engined T-28 reminds me of some commercial twins in it's nose shape or alternatively, the Me262.
-
Keep it simple. Stick with the single engine up front but switch to something a bit larger like an R-2600. I remember one of the guys over on What-If (Liegh Eaton) built a very much modified T-28 with larger engine (might have been an R-2800) that was almost too large for the ariframe. He adorned the wing with about twice the number of stores pylons and some in-the-wing guns. It was rather menacing at first glance.
-
Thanks folks. Rickshaw, I was reminded of the Me 262 nose too.

Maybe keep it contemporary? What about a Fury or Sabre canopy (and associated bang seat)?
-
An F-86 canopy would work well, too. By the time we're finished, you won't be able to tell there's a T-28 in there. ;)
-
Another variant was the Taiwanese AIDC T-CH-1

Basically a T-28 with a turboprop.
-
I prefer the lines of the YAT-28E myself for adding a turboprop to the T-28.
-
the good news is that a collector in the US has both YAT-28 prototype remains & is building one back to fly.
I do like that single-seater :)
What impressed me about the T-28 is its ability to generate heaps of smoke on start-up -- perfect for Hollywood or rock-concerts but I suppose you don't need the whole aircraft for that ;D
Sth Vietnamese markings ... when I took this it was a bit gusty & all the regular civil singles & twins like Cessna 172s & twin Comanches etc were wobbling all over the place on take-off .... the two T-28s held perfect rock-steady close formation from roll to split at 200ft.

Otay, late to this but an 18-cylinder R-2800 is dimensionally smaller than a 14-cylinder R-2600. The P&W lump
was actually rather compact.
I've posted these links before (multiple times on this and other forums, not that it's done much good :icon_zombie: ):
http://www.enginehistory.org/P&W/R-2800/DoubleWaspIndex.pdf (http://www.enginehistory.org/P&W/R-2800/DoubleWaspIndex.pdf)

Note that the overall lengths quoted are installed lengths, which means it includes things like externally mounted
two-stage intercooled supercharger/turbocharger systems. An aircraft like the T-28 could easily mount one of the basic
R-2800s without major changes to external appearance, which is great from a modelling standpoint. Yes, a real world
version would require major changes for weight and balance reaons, but these would not be externally visible.
Seriously folks, the real world data is out there and easily available in this digital age, so why not use it?

Don't you love the wingtip sidewinders:
