I did post about using my wings for lifting each and every time I fly. I have absolutely no aversion to using wing jacks. The problem for me is I never really need to lift the whole plane but typically only a wheel. I don't own any wing jacks and they are a bit more expensive than I want to pay. They also take up some extra room in the hangar. I have access to borrow them but it would take me longer to go transport them for use than to just use the little rig from Avery or one of the others as mentioned. I have seen methods for jacking with a floor jack and some blocking to the wing but that doesn't appeal to me. This is probably the main reason why many of us choose to use something other than wing jacks. If you have them available by all means use them. This is just my opinion however and I know there are others. Someone mentioned if something goes wrong and that is probably valid also. Any plane lifted regardless of the method needs to be secured. A wing jack is probably more secure than lifting the wheel with some form of pipe or avery rig. Make sure your plane is sufficiently choked. If your plane is nose heavy when picked up by the jack points I would sure double check my weight and balance. I am not saying either way because I don't know, but it would seem a little forward. Of course with a pilot in there it would be different. Were the tanks full?

Van's price is approximately $23 per strut, which turns out to be a fairly competitive price. I shopped hard on the Internet and basically matched this price from various suppliers. Van isn't such a bad guy after all!!

In addition to our standard features of time limited servo control, adjustable speed control, emergency reverse and simplified pilot/co-pilot wiring we now have models with that provide 2 user adjustable preset speeds. This feature allows you to control your trim response based on aircraft performance. This feature is especially useful in aircraft with a large performance envelope such as the RVs. For all the details please visit our website. www.tcwtech.com Thanks, Bob Newman.

Cencula" Subject: RV-List: Aileron trailing edge skislope effect Greetings listers, I'm working on my ailerons (RV-7A) and seem to be getting a skislope effect at the trailing edge near the ribs. Some places are worse than others. You can see what I mean by checking the third photo here: http://www.our7a.com/20071015.html or the second and third photos here: http://www.our7a.com/20071024.html Any thoughts on what's causing this? It seems to like the trailing edge bend may not be in exactly the right location. I sent this very question to Van's and got the following response: "Mike, I looked at your aileron trailing edge photo and it is not perfect, but it's acceptable and within tolerance. It will not cause you any flight problems. Bruce Reynolds brucer@vansaircraft.com" Although it's nice to know that it's still safe, I really need a *solution*. Thanks, Mike Cencula ________________________________ Message 6 _____________________________________ Time: 07:03:36 PM PST US From: "William Gill" Subject: RE: RV-List: Aileron trailing edge skislope effect Mike, It couldn't hurt to order another rib for the worst ski slope end to see if that improves the fit.

Remove the clecoes from the worst rib, and drill new holes that match the skins in the spaces between each of the existing holes. When you get to painting, fill the unriveted holes and then paint over them. 3. (Van's suggestion) Drive the rivets as-is, and rig the plane to fly straight and true once you're done. Personally I wouldn't go looking for extra work, but if pushed i'd probably opt for option 1. -Rob ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message rv-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/RV-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/rv-list Browse Digests http://www.matronics.com/digest/rv-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
