Depending on which way the gear retracts, the balance can also shift fore or aft during retraction- a single engine RG Cessna is downright scary when the gear is moving!! We have half a 44gal drum filled with concrete with a post embedded in it for nose gear aircraft, but for a tyre change on a taildragger, we tie the tail wheel to a ring set in the ground, and jack on side at a time at the jack point - this includes a couple of RV's we maintain for non-builder owners. The main thing to watch is the angle of the jack on the jack point - make sure it won't slip off, and you sometimes have to raise the tail to keep a good angle.

No, not a terrorist attack, or a porn site... but how to raise your Rocket safely. First let me say, don't you guys ever read my website? You are truly missing out on the world's foremost source of Rocket info, the oldest Rocket site out there and still the best. Prove me wrong. ;-) I had a worm clamp like Tom Martin describes fail on me while raising the plane. It does work, but be sure to use a quality clamp if you do. This was during the gear leg shortening described on my site... so I was asking a lot of the little clamp. Here's a couple shots of a pair of ordinary wing jacks being used under the motor mount. I made a couple of simple saddle pads that fit the top of the jacks and nested under the lower mount tube. This is a very sturdy, safe way to lift your bird since it keeps the weight right next to the gear... where it is normally found anyway! http://www.vincesrocket.com/checking%20toe.jpg jack setup http://www.vincesrocket.com/jacking%20the%20plane.jpg upper position http://www.vincesrocket.com/jack%20pad.jpg jack pad This is an EASY and STRONG jacking method. Weld a plate to an exhaust clamp and stick a jack under it. I can almost hear the whining already, "Ew, ew, won't that scratch my axle socket paint?" No, not if you're careful. And it's much better than punching a hole in your wing if you're tempted to use the wing jacks under the wing. I've used this setup THREE times on my bird so far, and the paint is fine. But, touch up the paint if you aren't so lucky. 'nuf said. http://www.vincesrocket.com/jacking%20the%20gear%20leg.jpg exhaust clamp jacking device I'm not a big fan of using straps on the engine mount, although I did it several times during construction when the total weight of the plane was hundreds of pounds lower. Just don't use the lifting eye on the engine unless you want to risk cracking the case. Ouch.
