I'm sending this to you privately (I think) since my plane is still S-LSA.
I put flap fences similar to what's on the CTLS on my CT2k. I cut them out of a plate of aluminum.
I did it to improve performance during negative flap operation. Even though I have no way of measuring the results, it seems obvious it would help. Sailplanes have been doing this for 50 years.
It may have also reduced the elevator bumping, but I'm not sure. I don't notice it now... but I really hadn't notice it recently either. Maybe I had just got used to it.
I just realized I don't have a photo, but they look just like the ones on a CTLS.
