The beringer system does look intriguing! At the very least I will probably order the 1.75” HD brakes I’m case I do go 35” ABW.
Is there any advantage to 1.5” axles vs the usual 1.25” cubcrafters axles when running these big tires over rough stuff?[/QUOTE]

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.
