I was wondering, has anyone ever done any R/C work for thrust vectoring? I know some people have done like the turkey feathers for F-16's and stuff but I didn't know about thrust vectoring. -Steve

Col. Thacker added vanes to his DF F-15 ACTIVE that are coupled to the elevator channel to vector the thrust. Works okay, but won't do a Cobra.

I know that Bob Parks has done some work with thrust vectoring. I don't think with models you can use the kind of vectoring that fullscale uses. The exhaust airflow is too slow in models so you'd need to use fins directly in the exhaust stream for it to work. I think.

The only thrust that Eric Dainty's Harrier produces is vectored thrust. http://www.ottawarcclub.com/ericd.htm

That's probably not the sort of vectored thrust that you were thinking of, but it IS the ultimate in vectored thrust. Paddles in the exaust flow of a more typical jet should produce significant pitch and/or yaw and/or roll control.

A Friend of mine built a home brew DF, based on a Sig Wonderer. Only he made it 80" wingspan and put a Dynamax & Os 91 in it.

He added a vertical fin and a horizontal stab INSIDE the thrust tube! they were coupled with rudder and elevator. Had it hooked to a mixer switch so it could be turned on and off.

He said it was squirrelly and didn't use it but once. Scared the
???t out of him

He offered to let me try it.

I flew it and tried the switch, I thought it was neat. That puppy would do some of the wildest things you ever saw!

Weird snaps, and I don't even know whatchacallits!!!! I had a lot of fun with it.

I tried to get him to bring it to a jet meet, but he didn't like it so he destroyed it, (Burned it) what a bummer

That harrier has a ducted fan with an OS90 in it. Are there harriers with real jet engines?

Oh, I forgot about Eddie Week's "Rig"

http://www.corpcomp.com/weeks1/Rig/Rig.html

I've tried it on an EDF but it lowered the thrust so much it wouldn't fly

Thrust verctoring will work no problem.
I built a DF model that used a 2D nozzle with out any problems.
Tom Hunt built a DF called the Hitech 2000 and it also worked no problem.
Both of our airplanes also used canards as a functioning pitch control.

Hi!
Does anybody know what happened to the site below?
I would really like to see it.

Joe McBride has a vectored hotspot. It uses the paddle-in-the-exhaust approach. Extremely effective. Cobras...the works!
Plus, Joe is the mang, mang.

You might be interested in the work of Prof. Benjamin Gal-Or at the Technion-Israel Institute of Technology. He flew thrust-vectored RPV's from 1987-1999 including models of the F-15, F-16, F-18, F-22 and Boeing 727. I studied under him from 1995-1997 and still keep contact. I may also be of some assistance since I am now working to transfer TVFC technoklogy to industry. These website might be of use:

The best one I ever saw was last weekend in Austin. Dennis from MS built a (corrected) Firebird with cannards and full fledged pitch and yaw thrust vectoring. A 22 pound airplane with a P-160. This thing could do any trick in the book and then some. There may be pics of it on another thread related to central tx jet rally.

Dennis has a Firebird. Not a Stingray. How much did you pay for Aeroshell.

I'm going to pick up 2 cases tomorrow. $154 per case of 24 plus tax
