I put the CF Bolly gear on mine. I got the large F3A gear.

I haven't used it yet as my plane is not complete. The concern I have with this gear, which seems to pretty widely used, is that it is swept. That puts a torsional load on the gear mount when landing and it seems it might twist itself out.

A friend of mine uses this gear and has experienced this on what I considered to be decent landings.

Mount this one securely or search for a CF gear that is not swept.
