The problem with the stock scout wheels is that they are 8" wide. So they do need to be replaced to run ABWs.

Whose STC? I could never find one. Up to 29" ABW are factory approved on the double puck installs. But those wheels and brakes add $2k to the upgarde cost. Either way, I already have them, so whatever, but honestly, the singles were nicer to land with. Couldn't lock them.

Alaska bushwheels STC. Maybe I just didn't read it properly, but I never saw anything about double puck brakes for my 31s. I wanted to out doubles on because the singles didn't hold all that well I thought.

I remember going through the Alaska Bushwheels STC when I installed 31s on my 7GCBC. I ended up putting double puck brakes on at the same time. As I recall, the STC said that "heavy duty" brakes were required. My mechanic interpreted that to be double puck brakes.

Ok. Makes sense. I guess "heavy duty" leaves room for interpretation. I know my citabria with single pucks on 31s braked better then some bushmasters I know of that have double pucks.

Ok, makes sense. When I did mine, AK Bushwheels said there was no STC, that all the Citabria's were Field Approved. Then I called the factory, and they said they had a drawing that approved the airframe up to 29" ABW's with no STC, so that's the route I took, which definitely required double puck. This was before AK Bushwheels got bought by Airframes Alaska. I realize a LOT has changed since then.
