Can you show us the shape of the enlarged fins ?

While this is not much of a problem or even noticeable when flying normally, on camera (and therefore FPV) it looks awful. However, by increasing the fin area by about 100% I have managed to almost eliminate it completely. It's so stable now that I can even fly round me in a very tight turn like a control line model at low throttle settings without it falling out the sky!
The stock fins looked a bit small to me, I am so used to looking at my twin jet
Can you post a photo of your new fins ? What material did you use ?
