REFLECTOR: Main Gear Access Dimensions

Sun Feb 20 08:12:06 CST 2005

Andy, Your keel looks lots like what I understood I was to be doing with
mine. I also found 2 great photos on Gilles Ross website at
http://www.immobilieretournesol.com/velocity/keel.html. Click on photos 196
and 197. His kit is an XLRG, too. I know that it's really not critical to
have the dimensions of this access cover exact, but I haven't started on it
yet, and I thought it would be best to do it by the book, rather than just
taking a swing at it.

And on the engine question, I haven't made a firm decision yet, other than
deciding that it will either be an IO540 or and IO550. I thought for
insurance purposes, I would rather stay with a certified engine. And since
Richard Riley has a lead on a 400-hour 540, I'm definitely checking into
that. I'm waiting to hear back from him now.

I followed an Ebay lead on a Continental 6-cylinder up on Saginaw Bay a
couple of weeks ago, about 200 miles north of here, but it was being used to
power a mobile hydraulic unit that was bought at a government auction. He
had no info on size, hours, or condition, and said that everyone who had
called about it was looking to put it on an airplane. I think he was asking
$2100 for the entire unit. He figured when he got some time, he would pull
the engine and put it on a pallet, and then auction the engine separately
from the other 3600 pounds of junk. Maybe he could get some info off the
engine once it was out of the unit. So if anyone's interested, keep an eye
on Ebay; it will show back up.

Speed brake! Oh yeah! I need to get back to that! Let's see, I was working
in the retract equipment so I could make sure it co-existed peacefully with
the speed brake actuator. I'm getting closer. I have all the wraps on the
gear legs, and I'm starting to work them into the fuselage. Coming up, the
transverse bulkheads, which don't look especially fun to do, but we'll see!

If you look at the picture you will see the keel stiffener bulkhead in the
keel opening.  I don't have the RG so I don't know how far aft the RG nose
gear actuator assembly is.  This is the aft opening and on my keel (a guess,
not a measurement) is about four feet aft of the canard bulkhead.  This is
not the cover that is forward of the control stick.

I use it to access the speed brake actuator.

You can see it in picture 264 on my web log:

Scott-
That picture seems to be pretty far aft of the location of the nose gear
access area- it is aft of the door opening-

No thats for the RG nose gear actuator assembly.  I just had mine off
and on...

Those access holes are right above the assembly and absolutely required
for installation and maintenance.

In your quote of the manual it says the holes are premarked, are yours not?
