Vectored thrust is very tempting, for a jet with re-heats!

I imagine that for a ducted fan, it would be way too lossy. As you already know, ANYTHING in the airflow costs thrust, so trying to 'bend' the tailpipe is doubly iffy!

Eric   Have you seen the models on youtube ? (no reheat)  Try www.youtube.com/watch?v=LgnFEgHfbvc    Thanks for reply .They dont "bend " the tailpipe but one guy put a simple flap for want of a better word at the exit .It works up & down approx 30 degrees I would guess ?Amazing results (on video) Never seen anything turn on its own length before like that & he seems to have a micro servo only to power it .Hence the request for info ?

Jetsome  Hmmm  Not sure what sort of thrust to expect . Some of my models (eg Bullet /Webra 40 powered ) I'd just let go vertically & get both hands on the tranny quickly .(showing my age again)

if you look at videos of the freewing SU35 on you tube ,these are amaizing, twin 70 mm contra rotating fans with nozzels fitted to the end of the jet outlet tubes, these vector the thrust up/down with the elevators, left/right with rudders and up/down with ailerons,they use 6s batteries and are amazing, give approx. 5mins flight,only down side is the inlets are really close to the ground O.K. if you fly off tarmac but if you fly off grass you pick up any debis thats on the runway -dont ask me how I know,spare fans are cheap from RCCastle in Hong Kong. Hobby king sometimes offer these planes at considerably cheaper price than Freewing stockists.

The Sebart Mig25 is another good example of this, very light, greater than 1:1 thrust:weight, these can be prop hung for want of a better description.
