<br><font size=2 face="sans-serif">I use the Great Planes .60 sized retracts. They are light but durable plastic, their struts seem to last forever (2 rebends in 300 flights), they come with axles and wheel locks. The best part is they have two opposed set screws on the axle (inside the retract). They only provide one set screw, but another can be picked up at the hardware store. Using two has eliminated struts every coming loose.</font>

<br><font size=2 face="sans-serif">For a few $$ more the MK retracts thru Central have very smooth action. We have a set, but they're not installed in anything yet so I can't comment on their lifecycle.</font>
