=C2-See Chapter 29T. Note that the gear, with the wheels off (if perfectl

selage and the camber angle (top of the tire towed out) is almost an inch.
=C2-Hence tire wear. If both tires are wearing evenly, the plane may look

pa trigear legs are extremely similar to the RV4 legs).=C2- The gear are
slanted aft on the RV and they tend to bend outward and twist back making f

the camber and creating toe out.=C2- =C2- All you can do is on the an

It might also be the effect of rolling the a/c backwards against the toe-in
of the gear; Other aircraft (eg Jabiru) display this effect. Otherwise, it
takes accident damage to induce a permanent set to the taper-rod legs of a
Rans S6, for example. =C2- Duncan McF.

Good evening
I have a feeling that the main gear legs on my XS are slightly out of
line. I think its due to a couple of hard landings. When I looked at the
plane (looking at the front from about 8m away) in the hangar today, it
looks as if its leaning slightly to the right.
I have checked the sockets and the re-inforcing ply in the fuselage and
all looks to be ok.
My question is, how easy is it to fit new legs? There is a video on
youtube showing a guy changing one leg. It appears all he does is remove
the socket bolt, pull out the leg, then insert the new one and replace
the bolt, job done. Is there any re-alignment of any kind to do?
Any advice would be much appreciated.
Thanks
Arwel
