Re: Modified video
Hey Jon.. when you get the tree to bloom Ben Franklins let me know!! Every time my wife has me go with her to the
garden centers I look for them money trees...I even ASK for them!!
On a more aircrafty question..does your RV4 engine mount have the RV7 gear gussets added? Just curious to learn if
you discovered cracking in the tubes or weld interface to
the main gear tube. Not all gears have but it is I believe a
point of concern during conditional inspection.
The fellow that does the recommended repair is located in Vancouver Washington.

Re: Hoop Gear Suggestions
That would work also. But as you noted, not much real estate to work with at the fuselage and canard junction. Lots of
challenge. Still, it is a possible venue. Steve..using the Grove gear, how did the ramp angle work out and the gear stagger
to bring the C/L of the tires to the MKII location from the Datum? You see why I chose the RV7 gear design?
Not only for reasons of working out a lot of installation issues , but the design has been flying the
Experimental aircraft sky
ever since the W8/W10 plans were sent by Mr. Wittman. I am skilled enough in TIG welding this is not a big event to fabricate.

Re: Hoop Gear Suggestions, Spring Steel design.
On the Dragonfly list there are members asking about the spring steel MKII design. I have a copy of the
sketch and it includes the materials used but I suspect it may be in the archives hereon Q-list. My printed
copy is not in the best condition but I can scan and upload
if there is no file available.
The builders longer term than I am probably have some history on this main gear design. I seem to remember
there were more than one or two aircraft that were revised to this design and the reports were it was quite a
successful change. Same issues about the glass de lams in the MKII original stubs. Since my project had the
similar overall questions about the gear I collected as much data as I could for options.
My canard has the glass stubs because I purchased it that way, but I am not going to use the spring steel, hoop,
or enhanced glass MKII gear. I am going with the RV7 (Wittman W10) main gear design. I already have new legs,brakes,
wheels..and wheel pants.
The engine mount design is already available since William Wynne built the mount for an Ed Luce Buttercup project he
was building. I have the plans for that aircraft also. Of course William intended to use the Corvair powerplant on the
Buttercup..as I am on Frankenbird.

Testing a few layups to see how size increases with time was my thought, I was just trying to avoid multiple shipments from AS&S. Michael, You are correct, DBFN 43 is the one that I am using for reference. It gives great information for the finished dimensions but doesn't say anything about the amount of fiberglass required. It also says S-Glass but that was corrected in later issues to E-Glass. Using E-Glass thickness of 0.012" the 5/8" thick section would take 52 layers assuming that the glass doesn't swell and another 52 layers for the 1 1/4" thick sections. I think that West Systems is the popular contemporary choice for resin but I am not sure.

I’ll add that the Garmin cameras have this built in as well. Many different options on how to display it within the app probably similar to the GoPro telemetry data.

I believe there are a few examples of homebuilt hoop gear in the Dragonfly newsletters; page 7 of Issue 43 is just one example. IIRC, a latter issue even had color photos.
Dragonfly Builders and Flyers Newsletter - Issue 43 For the Long-EZ gear finishing Steve posted, Ary Glantz has a nice video of that process: The Long-EZ Build: Chapter9 - Part 2 -- -MD #2827 (still thinking about planning on visualizing how to finish building)

You can find Boeing both process specs and BMS (Boeing Material Specs) online. You'll be able to find everything from ply thickness per ply to the different resins used for each application whether it's in an autoclave or an oven or room temp cures.

I have been trying to have a production run of hoop gear made for the Dragonfly list but have failed. I believe that I will have to
make my own. This leaves me with a few questions:
1. Are there any design improvements that should be included? I am thinking of adding 2 fiberglass sleeves for the final layers to help prevent cracking. 2. In estimating material to get to 0.75" thick, do I just use the fiberglass thickness or do I add something to allow for wetted thickness? 3. Which resin is preferred for a hoop gear application?

Hi Guys,
I have been experimenting with some software that I just bought which allows me to add some gauges (and a moving map) to videos with telemetry data. I added them to a video that I recorded this past weekend. Makes it more interesting…. to pilots anyway.

For what it is worth, the Long-Ez landing gear is made of unidirectional S-glass, from various vendors. The builder then has to wrap the gear with several layers of "BID" fiberglass/epoxy at a 45 degree angle. After the gear is mounted, then additional plies may be needed where the wheel axle mount to provide correct alignment for "toe-in", etc.

As for the final thickness, I would do some test layups to determine the number of layers of glass for the final dimension. You might want to read up on "post-curing" the epoxy/glass part too. Hope this helps. Steve
