Not sure what the ultimate in thrust is, In my case I use one of these:
http://www.jetcatusa.com/p200.html

Buy your own P-200 here:
http://www.sitewavesstores5.com/mm5/merchant.mvc?Screen=PROD&Store_Code=JetCat&Product_Code=P200-SX&Category_Code=

The JetCat P-200-SX, has 52lb of thrust at 112,000RPM..
I fly my F/A-18 which weighs about 49 lbs fuelled on that plane, which gives me a grater than 1:1 T/W ratio which is FUN! :joystick:

So far as I know this is the most powerful commercially available turbine for hobby use.. there may be something with more thrust, that I am not aware of, and it is very likely newer more powerful stuff is in development...

WOW!  That is something.  i am sure they will get bigger and bigger to a point that we will see people flying on the big R/C.   I hope it is worth the money, a bit to much for me for i will most likely crash them on the first take off.
Oh, do you have insurance on them?

the only insurance is that you ensure your thumbs are up to the task of flying it!

Crash that baby and im out close to 15 grand...
Turbines tend to burn upon crashing, just like the real thing... and usually nothing is left that can be salvaged...

Should that guy be smoking over the Sr71 while they fuel and start it?

hmmm i was just planning on ordering C-123K plans that were 1/6th scale. That would give it a 18.33ft wingspan, length of 12.7ft length and 5.6ft height but hell, i might as well just go up to 1/3.66th scale which gives me a 30.05ft wingspan, 20.83ft length and 9.28ft height. That would be bigger than that b-29. The advantage i have is i have a real c-123K to use for all my references of detail in addition to the plans at my fingertips since i work at a museum that has one and i only live 2min away from the airport. My goal for it would be to get it built take it on a few airshow (both real planes and RC) circuits and then donate it to the museum. I want to detail it just as our real one is though so it will look like this:


I havent decided on what construction im gonna do. Most likely wood, though i do like the idea of it being composite, but i think thats just out of my reach with its size.

completion time 1-5years lol

NICE Plane!

The most astonishing part of that whole video is that the old boy's *wife* actually appears to be out there helping him with his giant toy plane.

i found the video of the B52 crash. I actually wasnt even looking for it, but instead was reading on a site about giant scale planes.

ive actually seen the video before without realizing that it was the one mentioned above...

Typical turbines cost around the price range of $2-5000. Then you have to add the recivers wich in that case they prolly have around 5 or 6, $180. Two or more transmitters, $300, and I can go on and on but that model can go for about the cost of a pourche.
