Default Carbon fiber vertical fin??

I was contemplating getting the carbon fiber vertical fin, as the stock one is flimsy and seems to break very easy... Is there any drawbacks to getting a carbon fiber one???

Vibration problems can be worse with a CF fin since they tend to be thinner than the stock fin. I tried the RKH "style 02" fin and it resonated far easier than the stock fin. I think the RKH fin is 0.75 mm thick. I even tried adding pieces of split CF tubing to the leading and trailing edges and it didn't help. That's the only CF fin I've tried, but IIRC there's been at least a few others (koi-fish was one) that have went back to stock after trying a CF fin.

No drawbacks, but it may amplify vibes if your tail isn't perfect.

I just cleanly wrapped my vert tail fin in packing tape, cut the center holes out and folded over. It adds a little bit of strength and mine's held up to some pretty good smacks so far.

So, opening up the OP's topic a bit in an obvious direction, suggestions on improving on the stock tail fin can be found in the thread at Tail Fin Fix


I like the music/piano wire idea mentioned there, but haven't tried it. The wire can be a bit longer to help with landing in grass, won't break, and some flex in it should help save a few split tail booms as compared to a rigid fin.

I put a piece of 2 mm carbon fiber rod along back vertical section of the stock one. Got tired of them breaking on landings seems to work. Already had the carbon fiber rod laying around.
