Billy, I know nothing of the type we've been discussing. But, in general
There are no stops in the design....... I need to call Tecnam again for advice but I can't say that their support has been exemplary
Is very worrisome to me! Every flight control stops at something, and the thought that your aircraft seems to not define that mechanically is a huge red flag for me! That says to me that something somewhere will either operate other than intended, or be damaged when the intended travel limit is exceeded. I've done a lot of test flying to assess control in modified certified airplanes. I've had a few scares with wrong flight control set ups - and they were defined! To be honest, for the information you have been able to provide thus far, I would decline to fly the airplane until these were not questions any more. I have found every now and then in aviation, something tells you to stop everything, and get more answers.
A newly modified airplane I first test flew this past spring, and test flew for 60 hours, had a few "not good enoughs". I tested for them, documented them, suggested changes, and suggested cautions for further flying to be done by a couple of other test pilots also flying the program. A week after briefing the next new test pilot, his check flight ended badly, there was a problem with control of an airplane system. They were too low to take the time needed to understand the problem, and mitigate it. They're okay, but a million dollar prototype is pretty badly damaged now. In hindsight, I might have popped up a redder red flag.....
A few responses in this thread read like red flags for your project to me, good on you for asking. Now you have to decide what to do going forward with a "not good enough" in your airplane...
