    FluiDyne C2200 Support Leg question

    I am setting up a set of Fluidyne C2200 on a PA-18 and the Installation instructions call for an extra support leg from the ski bracket to the forward fuselage gear bolt. It looks like like a lot of guys are running around without this installed. It seems like the angle that the ski bracket is welded to the gear leg dictates the need for the extra support leg. The ski brackets that are welded inline with the flight path have an extra gear leg and the ski brackets that are welded at 45* or so down don't seem to run the extra leg. Anybody know why this is?
    Thanks!

    When I bought used C2200 from a fellow in Anchorage many years ago the support let was included, and I used it until I installed Atlee's heavy duty gear, at which time my mechanic felt it was not needed. I think this was confirmed when I bought the STC from WipAire (who now owns the STC) and the diagrams had no mention of that support leg.

    In looking at your two pictures, the one without the brace has a beefed up gear leg to axle joint. The one with the brace does not have the beef up. I'll suggest that the reason for the brace is the offset loads on the welded joint between the axle and the V​ gear leg tubes. Without the brace that joint will likely crack with the abuse from the skis.

    What he ^^^ said. Without reinforced gear, I'd do the extra leg. Maybe even with reinforced gear I'd do it. Lots of nasty forces possible on skis.
