I just upgraded to new main landing gear from Cube's
http://www.thorpcentral.com/These are shipped in a plywood triangle box with the lower gear legs set in the box across the bottom. Cubes says this keeps shipping costs down. Shipping was just under $250 to the Seattle area, so it must be killer expensive to ship as a full assembly.
These lower legs are held in place by 3 bolts/nuts each. Assembled, they are longer than my original gear.
With the wheels & tires on the gear and the engine on the fuselage, the gear seems more limber than the original gear. Perhaps they will soften the landing a bit.
Some hand work was required to install: The top clevis had to be filed open a bit to fit the aluminum bar at the top of the fuselage, then ground back to clear the top motor mount clevis, also a small amount of grinding for the lower right motor mount weldament and the gear tube so the bolt could go in with clearance between the motor mount & gear frame tube.
The lower tabs on the gear were perfect, the engine mount lower legs fit in with just a tap if the hammer. I just needed to kiss the assembly with a drill bit to get the bolts to press into place.
Over-all, I think that having the gear clevis a bit too tight, or slightly oversize is preferable to 'too loose or short' as a minor bit of hand work gives the perfect fit.
Kudos to Cubes
Next install the cowl to see if the propeller extension still passes thru the center....Nothing is usually this easy.
