I've become a believer in heat treated 4130 tubing gear legs. I have no idea if they are heavier or lighter than the stock gear legs, which I know is always important to you for staying under 254#.


Thom,

I really don't want to get away from the aluminum legs. They are a great safety feature in that they do bend so easily. It saves the cage and the pilot. I want the cable to act as a fuse that breaks when the load becomes too great. This will absorb a lot of the impact energy from a plop, and then, if necessary, the leg can bend to absorb even more.

The cable will have little to no effect for dropping a wheel into a hole. I see this as desirable. I would want the leg to bend to the rear to save me and the cage. If, I can remember to use five degrees of flaperon, I should be going about 26 mph under no wind conditions.

The good thing about bending gear legs is that it makes you re-evaluate your landing technique. Lately, I have been making very, very good landings.
