I started making my own fins.

 

if i want to upload a track it works only if i select a fin.

 

i cannot add my own fins (blipfins http://bf.c-bra.info/index.php/products/fins/5-bf-blade-8 )

 

so i have to select any other fin and write the fin i used in the comment

how can i

- add my own fins

- if this ist not possible  upload a track without a fin selection?

I have added the fin brand.

 

greetings

Thanks a lot !
