Adamson" : When I talked to Tim Ong before OSH, he said they would have a kit there for purchase that included VG's and some other stuff. It would provide a 5kts buffet prior to the stall. They were in test with it at the time. Perhaps they have not completed their development. I know where the stall strip mold is that was originally designed for the Legacy Wing, however after talking with Tim, he suggested that stall strips alone would do nothing. BTW, they go 12" inboard of the wing joint on the stub wings if anyone is curious. I talked to the wing designer about location, etc. If you have AOA, you could accomplish the same thing. Just set the speed for the warning to be about 5kts prior to stall in whatever configuration you want it. Then you could practice stalls and when warning triggers even without buffet, you recover. Unfortunately, this isn't fail proof as there are lots of configurations that you'd want that set. BTW, I hear that the Chelton has a software AOA, anyone know if it's non-configuration dependant? Perhaps between the two, you could build a set of warnings that would address the notification issues... This is also an awkward topic that I'm not sure of the answer too. If you read the CAFÉ report, they testing stalls in all the configurations and while there was no warning, it didn't appear that you would immediately end up upside down either... So, you want to know where it happens, and how it happens.... ONCE, then you don't want to go there on purpose again... How do you determine that without getting in trouble, especially with no flight warning...hmm... Where are all the test pilots, I'm sure they have some suggestions? Alan - about to start build assist.
