Really nice, really strong set of tri-gear mini retracts, suitable for foamie jets and warbirds, or our Cessna 310. The nosegear unit is steerable, using a special mount for a servo that goes directly on the leg. Wheels are included, and the legs can be shortened or lengthened if need be. These sets are rugged, not junk, the best out there for smaller planes, capable of handling a plane up to three pounds or so, even off grass. Includes all sorts of hardware bits, servo linkages, lots of good stuff.
