|Someday you’ll need to jack up your aircraft to install new tires, clean & grease wheel bearings, or fix a flat. This nifty jack stand is safer than using an engine hoist or the wing tie down location. Requires a modification to the axle nuts (about 1 hour). Kit includes the axle jack arm, axle nut modification hardware, & directions to modify the nuts. For hollow axles (Wittman style) Gear only. Uses automotive bottle jack. Jack not included. Not for RV-8s. For RV Gear Legs with Hole in Axle.|
I used this for my GlaStar with success. If you have wheel pants, you will have to make accommodations for the nut that secures the wheel, as with the covering of the axle you cannot properly secure it once off (spinning the wheel and tightening). The jack comes with a kit to make these modifications but I did not need to do so, as I dont have wheel pants. It definitely gets a little springy with all that weight/leverage on the Whitman gear and I wouldnt want to use outside in a breeze but it did work as needed for tire change/rotation. Long of the short: Off the shelf, with little modification, this is the best solution I could find for a GlaStar leg. I had used the hose clamp solution but they kept slipping and messing up my gear leg paint, no matter the tension. This (by aviation monetary units) inexpensive solution is well built and served my purposes and I suspect it will for others as well.
Per the vendor: The tube of the #561-1 jack stand is 12" long x 7/8" diameter with an inside hole of 1/2" (wall thickness of the tube is 3/16"); the end of the tube that goes inside the axle is turned down to .560" diameter x 3-1/2" long (this slides inside the axle). The jack stand is designed for the RV kit aircraft which has a 7/8" (.875" hole drilled in the axle). I'm not sure of the GlaStar axle hole size, but it should be about the same. Best bet would be to measure the hole in the GlaStar axle to be sure of the size.
Per the manufacturer: once the aircraft is jacked up and off the ground, the axle nut can be removed and the wheel assembly slides on to the tube. You can then lower the axle on to some wood blocks to secure the aircraft, and then take the wheel assembly off and do the necessary maintenance.

Yes, this will work on the RV9, just not the RV8.
PER THE MANUFACTURER: This Jack stand is designed for the Van's RV aircraft (and other experimental aircraft) that use the Wittman style steel gear legs that have a 7/8 (.875) hole inside the axle part of the gear leg. This hole is to lighten the gear leg, and the 7/8 hole is drilled about 3 to 4 deep in the axle porting of the gear leg. You may want to check your airplane axles, and see if the axle has a hole in it, and if that hole is at least 7/8 diameter and about 3 to 4 deep. The jack stand would probably work, if that hole size is in the axle.
