Legs wheel replacement
I used a jack under the wing last night on my RV-8. We started to jack both
wings but realized the cg was forward of the jacking points when the tail
wheel started coming off the floor so we put some weight (carefully) on the
horizontal stabilizer and jacked one side at a time. Worked fine, was very
stable, and it allowed unencumbered access to the wheel.=0A=0AAs someone e
lse implied earlier, the wings support the entire weight of the plane when
we're flying and can support several times the planes weight when flying. B
esides, Dicky V. says that the tie down mount is fine for jacking the plane
. If he says it, it's probably true.=0A=0AJohn

Legs wheel replacement
I should have elaborated when I posted my comments about the jack. 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?

FYI,
The tip-up canopy struts supplied by Van's are Lift-O-Mat PN/752818.
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!!

Fellow RV builders,
I'm pleased to annouce we have added two new models to the Safety-Trim product
family. 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. Rv-10

| Subject: | 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.

Although it's nice to know that it's still safe, I really need a *solution*.
Thanks,
Mike Cencula

Mike,
It couldn't hurt to order another rib for the worst ski slope end to see
if that improves the fit.

Some alternatives:
1. Make a new rib for the worst location, drilling holes to match the skins.
2. 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.
