That just looks RIGHT.  Beautiful job!   You all know I have a soft spot for all things Jetstream.   :thumbsup:
So I got that going for me...which is nice....

Nice one Chris, it looks like a natural.  :thumbsup:

Re power, with actual Jetstream engines (Astazou XIVs at least) it would have gone up from 1000hp total to 3360+hp total, which is a bit much, even for a hot'n'high conversion of a significantly underpowered aircraft. However, you could always claim that they are earlier, lower-powered Astazous. The Astazou II only put out 440hp, so that would give it 1760hp total which is much more reasonable, putting it in the ballpark of the ST-27, which had 1430hp (although that was also stretched).

The first version of the Potez 840 had 4 x 440hp Astazou IIs. It was smaller, heavier and much faster than the Heron, so it seems reasonable to suggest that a Heron development could have absorbed the same power.

Two things I know that pilots like in an aircraft - a lot of power, and a lot of wing. 

I read somewhere a pilot's comments that the Lighting was the most ridiculously over-powered aircraft ever, but once one got used to that it was very much a "pilot's aircraft."

Another said that the only aircraft built with enough wing was the Vulcan, and it, too, was a "pilot's aircraft."

Too much is always better than too little...................  ;)

No such thing as too much power.  As long as you can use it.

Good job Chris.

- Can't be bothered to do the proper research and get it right.

True, but then service/airline pilots rarely have to pay their own fuel bills... ;)

Rumour has it that SR-71 crews thought it could do with a bit more power at times...

Yeah, and they were always so limited on altitude as well..................  ;D ;D ;D ;D ;D ;D
Kit's Rule 1 ) Any aircraft can be improved by fitting longer wings, and/or a longer fuselage
Kit's Rule 2) The backstory can always be changed to suit the model

Thankyou Chris, I  might buy another one of these  as I have another  set of engines  so I  will have to think of  another  job for one.

Those dont look like Astazous though.  They look like Garrett nacelles though on Jetstreams the intake was on top.  On the 31 the TPE-331 was rated at 940shp if I remember correctly.  On the 32 it was bumped to...1020?  Those numbers sound right.  It's been a while though. Lol.
So I got that going for me...which is nice....
