So I tried to get some testing in Sunday so after finding a decent place to run I got to it only to run into handling issues. The car was doing a big back and forth weave (not a wiggle like an over aggressive gyro can cause though) and it eventually ended up causing a crash, don't worry I will get crash damage pics up later. I was lucky though and it didn't seem to hurt any electronics or the central core of the car.
It really felt like I had to much rear downforce and that the car could not get enough load on the front to track straight. I am going to make some changes to the setup on my gyro though as it is possible it was acting up but I am not sure yet.
So I am going to stop using a rear wing and switch to just big upright vertical stabilizers as I think they will make enough downforce with drag to keep the back down but not so much that I have handling problems. The big decision is how big should I go, a very large side mounted stabilizer (dark gray) or a smaller rear deck mounted one (light gray). I am thinking I should go big as I can always trim it down easier than add to. Given enough time I will try both but I still have many other things to try to work out to match a given wing setup so I have a good overall package.
On an upside I think I have found a better place to run as I have gotten permission to use a closed airstrip that is supposed to be in decent shape (I will check it out this weekend to see for myself). Hopefully it will work out.
