I got the Midwest stand because it fits my R-54 perfectly and it gets the plane up in the air so I can comfortably work on it. Then comes my F-22 and the stand will not accomodate it. I made cross bars that bridge the cradle uprights. The cross bars are PVC plumbing tube with pipe insulation slipped over the tube. I used 4 plastic cups (could use PVC caps also), secured to the cross bars with screws into the PVC and spaced to fit over the cradle uprights. Works like a charm and it's fully collapsable. The bars come off for the R-54 and go back on to hold the F-22.
