So the shaft of your axi coming out from the plane side ?
I know I can reverse the axi like in the photo I added, I saw in the link you gave me that they do it also.
If I reverse the shaft and use 1/8 inch collar I can use my 3.2 prop adapter that I already have.

Good to know about the fiber mounts, looking good.

I thought I can trim the ikarus mount a little bit so it will fit the axi.

Thanks.
