Thanks for all your useful information. I really learned quite a bit more than I thought I knew regarding the stall system. There's the old adage, you never stop learning. Once again thanks for all your help.
The stall test went off without a hitch. Just like everyone said, prepare for everything and be ready for anything. It was a nonevent. pusher came on as on cue and pushed nose down. The aircraft went straight ahead which was a relief, but also a testament to the work being done properly.
Thanks Again to all who responded
