Default X29 Fighter

Hey guys when I was a kid I has a modle of a F15 and X29. I dreamed of these 2 planes as a kid

Well I got my F15. But looking for a turbine x29 or SU47. Are there any kits for these foward sweeping wing jets?

It's sad. I just picked up a Byron F20 it looks like it could be converted to a X29 with some work

I know someone had a magazine article that converted the Byron F16 to an F16XL, i vaguely remember seeing something like that for the F20 to a X29 as well.

Ya I had a Byron F16 that I was going to convert to a XL but the planes I bought for it didn't mach and it had a lot of complex coars that the foam cutters didn't want to make

IIRC, the X-29 would not fly without the onboard computers. Not sure how you'd duplicate that in a model?

Pretty sure that article was done by the late Ivan Munninghoft "sp". I think I have the original article here somewhere.

Both the X29 and the Su47 have flown successfully as models.

Turbine model Su47

Ron Sweeney had a IC ducted fan model that flew many years ago in the UK. It had no gyro. It is a common misconception that these planes need a gyro because the full size will not fly without computer aids. There is a foam Su47 that flies very well.

You have to be sure to make the wings have 'wash in' rather than 'wash out'.

The main reason full scale jets need an FCC to fly is not necessarily because they are inherently unstable, it is because the design CG makes them unstable. F-16. for example, is tail heavy by design. FCC compensates for that, but it also allows for great manouverability when the flight control laws are "relaxed" during specific flight envelopes.
But we know we can adjust the CG of the F-16 and make it a very good flying, stable, airframe.

Same applies to te X29, SU-47.........get the right CG, and they will fly good.
