Forward Swept Wing
If all goes well you'll see two pictures of Forward Swept wing aircraft. One is of a full size NASA/Grumman project, and the second is a .40 R/C kit by a Cal. designer. Both flew very well despite what others said to the contrary somewhere else on RCU. The picture of the model was scanned from a small ad that ran in RCM some years back. The model is an "Inversion 40." Approx. 60" span, .40 2 stroke. Nothing exotic, just a simple box fuselage, balsa sheet tail surfaces. Foam wing, with reverse sweep the only unusual feature. A club member flys his regularly and it is awesome. The kits are no longer available. It is very fast, highly manuverable and slows down to a walk for landings. It has been radar clocked across our field at 90 MPH by a cop club member. Forward Sweepers do indeed fly, and fly well.

HFB 320 "Hansa Jet", business jet, built in Germany in the 60s & 70s, went into series production, but was not succesfull, I think only 30 or so were built.
And : Schleicher Ka7 2-seat sailplane :

I've seen that Hansa Jet before but I just couldn't seem to remember what it was called. Sure looks impressive to me.
I have a new FSW on the drawing board right now that if is flown successfully I may produce some plans and maybe even a kit or two. 55 inch wingspan 54 inch long, 15 degree forward sweep. Hopefully will make for a groovy aircraft.
If all works out well it should even be able to fly Sportsman and Intermediate pattern maneuvers considering that the don't add any tip-stalling maneuvers.
