I still don't know what exactly happened, but the Piet I saw that ended up upside-down on the runway due to broken landing gear had the Jenny-style gear (bungee snapped, but why...?). Anyone have any statistics? I have to decide on gear myself one of these days (if those darn plans ever get here... [grumble]).> Aw shucks.

Thanks JimThat's what I had been wondering about. The Tall split gear probably makes the most sense from a safety point of view.J Mc________________________________________________________________________________

One thing I failed to consider in my first post was the height of theaxle above the ground. My Flybaby had 8.00 x 4 tires so the axle wasclose to the ground. On a Pietenpol the wheels could be wire wheelsputting the axle much higher off the ground. Still could be a problembut not nearly so bad.Jim Skinner________________________________________________________________________________

Little more cush. Also w/the straight gear you can wrap and re-wrap the bungee chords untilyou get the right amount of give. Too loose and the wind cantip you side to side too much, too tight and the tires and airframetake bigger jolts. There is no alignment issue w/ the straight gearlike you have when you weld up the split gear. It's true from wheelto wheel right away. I hear from those much wiser that a planewith wheels pointed in different directions can make it a wholedifferent animal. Hopefully others w/ more experience will comment.

I think that I favor the split gear because of the greater potentialcushoning effect. How do people build their split gear?It occurs to me that I could weld the Vs, them temporarily mount them tothe fuselage (or a jig), then slide the two axels over the ends of a longpipe to insure they are parallel, then tack the assembly into position.Remove the pipe and: TaDa! parallel axels.I'm a beginning builder and not an experienced metal worker so I don't havea lot of confidence in this idea, but it does sound reasonable. :-)Randy Stockberger>>>I would be interested in hearing from those of us who have flown with >>the different styles of landing gear.
