Hi Gang I have a P1 and I just got a set of knock-off Vision props and guards. The props are the correct 9.4 inch diameter and the guards appear to be 10 inch diameter. This means that the prop tips are well inside the guards (see pic) and, if the guards flex, the prop tips will hit them. To me this seems like they defeat the purpose. Do the factory Vision props and guards look like this? Thanks.
