With the installation of the shear webs "locking in" the washout, the washout tabs on the bottom of each rib can now be removed. I used a razor saw to cut away the tabs on the plywood ribs, and an Exacto knife to remove the tabs from the remaining balsa ribs. If you are going to be "off", it is better to err on the side of leaving too much material -- as this can still be sanded to the proper airfoil shape; than to cut into the airfoil, thereby altering its shape.

When using the razor saw, be sure to hold the end of the saw away from the trailing edge sheeting.

Here is the view of the bottom of the wing panel from the tip rib, after cutting away the tabs. Note that if they are not perfectly flush, I left just a little bit of the tab material behind.

The next step is to sand any excess tab material -- and that of the wing bolt reinforcement block -- off, so that the bottom of the wing is properly contoured to the airfoil shape.

A solid surface is also necessary for properly mounting and securing the aileron control horn. A filler block is needed at the point of installation of the control horn. Tim purchased a length of tapered aileron stock for this purpose.

Beings we are building 3 of these planes, simultaneously, I cut 6 lengths -- each approximately 2" -- on my table saw.

http://www.rcuniverse.com/forum/atta...mentid=2138017 http://www.rcuniverse.com/forum/atta...mentid=2138018

Each 2" length of aileron stock was beveled slightly on each side to match the contour of the airfoil, when lined up with the tip of ribs and the beveled edge of the trailing edge sheeting. When happy with the fit, apply medium CA and glue to the sheeting as shown.

We repeated the process to this point to build the other wing panel for each of our wings. Obviously, the only major difference in the process is that the layout of the pieces is a mirror image of the first panel, so that there is a left and right matching pair of wing panels.

Here, I am installing the plywood ribs to the bottom spar, in reverse order, for my left wing panel.


http://www.rcuniverse.com/forum/atta...mentid=2138025 http://www.rcuniverse.com/forum/atta...mentid=2138026
Here are the two largely completed wing panels for my wing (foreground & right), and Tim's wing (background & left).

Although there is still more to be completed with the wing, before we could say the wing is "done", we decided to stop on the wings for the moment, and turn our attention to starting the fuselage.

Construction of the fuse begins with slicing through the retaining tabs to release the laser-cut parts from the remainder of each sheet.

http://www.rcuniverse.com/forum/atta...mentid=2138073
Eric cuts his ply formers free from the cut-sheets.


http://www.rcuniverse.com/forum/atta...mentid=2138077
I do the same; and many ofTim's are visible towards the back-left corner of the bench.

Fuselage construction begins with the top half of the fuse.

Tim stacks all the top fuse formers into one pile, and snaps some pictures . . .

http://www.rcuniverse.com/forum/atta...mentid=2138082

. . . while Eric and I continue to cut out all our parts.

http://www.rcuniverse.com/forum/atta...mentid=2138084

There are laser-etched marks on the firewall. Using a ruler, these marks are used as a reference to draw "crosshairs" for the wing dowel retaining hole, and to mark the thrustline in order to center the engine mount.


http://www.rcuniverse.com/forum/atta...mentid=2138085

The top fuse view of the plans were laid out on the workbench, as well. Unlike the rest of the fuse, the firewall does not have a top and bottom section -- it is one piece. Therefore, when building the top half of the fuse, the firewall will extend off the edge of the building surface, so the plans need to be aligned with the edge of the bench, accordingly. Carefully fold the plans at the back edge of the firewall; and suspend the portion in front of this line over the edge. Note that any misalignment could result in unintentionally introducing right or left thrust to the finished fuse.

http://www.rcuniverse.com/forum/atta...mentid=2138086

The engine mount (the Dave Brown 60FS mount is pictured) is aligned with the thrustline and is tack-glued with four drops of medium CA, in preparation for drilling holes for the engine mount bolts and blind nuts.

http://www.rcuniverse.com/forum/atta...mentid=2138090
Tim shows Eric how to use the GreatPlanes centerfinder for marking pilot holes in his firewall; and, the engine mount is then removed.


http://www.rcuniverse.com/forum/atta...mentid=2138093
Pilot holes are marked on my firewall; and, the temporarily tacked engine mount can now be removed for drilling holes for the blind nuts.

Anyone following this thread, please give Tim and I some feedback. He would love feedback as to what you think of the design, thus far.

Additionally, I would appreciate feedback as to how my write-up of the build-log is working for you. It is a tough line to walk in order to give specific enough details regarding what we are doing, and the reasoning behind those choices to builders that are not very experienced, while hopefully not simultaneously "turning-off" more experienced builders by being too wordy.

What do you think, thus far?

Here is some feedback...build a HE100!

Do some short build videos for each segment. Of course your videos, may be as "wordy" as your posts.

Where can a guy buy this short kit and plans? I googled "8th Scale Aviation" but no dice couldn't find it.

Tim should be monitoring this thread so he will probably contact you. Ollie can let him know. I think Tim has a Facebook page too. You are at the right place so hang tight.

I sent you Tim's email so you can contact him directly.

Thanks will do!

If you want to contact me, email me about planes at [email protected]

Thanks Tim

What Size Jake??? :p

Just keeping it quiet Ollie does such a great job of explaining procedures!!! :rolleyes:

We drilled the holes in the firewall that were marked in the last step, and installed 6-32 blind nuts from the back side. After pressing them in by hand, I applied a couple drops of medium CA and set them in firmly by tapping them in with a hammer.

http://www.rcuniverse.com/forum/atta...mentid=2139364 http://www.rcuniverse.com/forum/atta...mentid=2139365


We then drilled the Cowl Mount's three pre-marked holes for 4-40 blind nuts and set them in the same manner as with the firewall.

Firewall and Cowl Mount with blind nuts installed.

1/4 x 1/4" balsa stringers are pinned to the top view of the plans with T-pins. Then, the main (top) formers are placed per their locations on the plans, aligned with a builder's square, and glued to the stringers with thin CA. We started with the rear-most former, and worked our way forward.


Tim gets his stringers pinned down:
http://www.rcuniverse.com/forum/atta...mentid=2139374


Eric mirrors our excitement that things are finally taking shape, while ensuring his formers are glued at right angles to the building surface:
http://www.rcuniverse.com/forum/atta...mentid=2139375 http://www.rcuniverse.com/forum/atta...mentid=2139376

Tim and I get our formers glued-in, as well. Tim marks a centerline on one of them (although I don't remember why).

http://www.rcuniverse.com/forum/atta...mentid=2139387 http://www.rcuniverse.com/forum/atta...mentid=2139388

I would have to see it to know why. ;)

I very carefully set my firewall in-place and check all angles. As stated before, any variance when installing this piece could unintentially introduce right or left thrust in the finished model if the plans are not set up properly to the edge of the work surface. Likewise, this former must absolutely be installed at a perfect right angle to avoid unintentially introducing up- or down-thrust.

http://www.rcuniverse.com/forum/atta...mentid=2139389
Take your time with this one!


http://www.rcuniverse.com/forum/atta...mentid=2139390 http://www.rcuniverse.com/forum/atta...mentid=2139391
This is one of those steps when you wish you had 3 hands: one to hold the square, another to hold the former in-place, and a third to apply the glue. So Eric gives Tim an assist when Tim installs his firewall.

Gee, thanks Eric. Where were you when I needed help? :p
