I’ve never had 1 1/2’” axles. So can’t answer that. I know the 1 1/4” on the FX3 is HD which and is what I put on all of my cubs including my SS. 1 3/4” brakes would be a lot on 8:50s. You literally have to try to push the pedals thru the floor with the 6” grove calipers with 35s. I almost end up in a pond the first time I flew them. I have put Beringer masters with the grove calipers on 2 cubs now. Works pretty darn good. It’s uses a smaller dia piston. Low volume high pressure. You get a lot more pedal travel, which gives you better modulation but a lot more pressure when you need it.

Chuck, I have the Grove 1.75 dual piston and running 31" tires and stopping power of that setup is not all that great which I understand is somewhat normal with 31's. It sounds like the Berringer brake system a better option, are you using the two or three piston? how much better do you think they work over the Grove? I don't have any experience with the Berringer's.
