Default Best thrust to weight ratio ducted fan jet?

Hi,
what is the best ducted fan jet in terms of thrust to weight ratio, limited by a budget of around $100-200? The model should also be at least reasonably maneuverable, I'm not looking for a missile. :-)

of course it depends on the weight of the plane itself. for $2-300 you wont find much . I ca ntell you that a byron fan puts out about 13-15 lbs of thrust but they arent usually found in aerodynamically clean setups.....but they do fly larger jets

I don't care what the weight of the vehicle is as long as it has a good thrust to weight ratio.
What about e.g. this one? http://www.graysonhobby.com/catalog/...7972c7e3946824

I think you mean Electric Ducted Fan Jet (EDF) 'Ducted Fan' are IC powered models somewhat from yesteryear.

To answer your question in respect of EDF I would advise any of the RC Lander smaller planes or the Phase 3 F16

ERHHH, Hold your plumbs big plums. He may mean IC DF and despite the latter day connotation, Paul Gray is correct, the OS/Ramtech is still the best combo. 200 usd might just get him some batteries!!! The best model is the jmp/yellow aircraft Starfire. This set up will keep up with most of the turbine or edf powered model. My pal Carl Jackson achieved 221 mph at Helchteren (pampa) a few years ago. Best wishes to all, Ron.

Best bang for buck at the moment in the throw in the car type foamy is the "Centry UK" Vortex.

Very cool… NitroPlanes sells that in the USA. I’ve been looking at it, but I thought that it may not fly well since it was so small. I may need to order one. (the first vid was great)
