Hello all this is my first post and I have a question about props for my Proboat Veles. The manual states that the box stock prop is recommended for up too 4s and if using 6s constantly to use factory replacement part # PRB282027 which is a misprint it's actually #PBR282028. So my question is has anyone run into the problem of the hub on the replacement being too short too allow tightening down of the prop...? I attached pictures of Box stock and Factory replacement.

Thanks in advance. Ken
