Brison 3.2 is a single bolt so I think your BME will work.
I am not sure of the center hole.
ORIGINAL: flatlandmike
I have two 22a vess props one is drilled for a bme and one is drilled for a da50 if any one wants to try one of these ill lone one to you for the cost of shipping if you like it and want to keep it just pay me for the prop later on, and if you are done testing with it just send it back.
what bolt patern is the 3.2
