Let the games begin! I will be doing a running review of my build of the Genesis 1/3 Waco YMF-5, distributed by RC Showcase, over the coming weeks/months for those of you that are interested. This is one monster kit and at the first look in the two huge boxes. it appears to be somewhat intimidating, more on that later. When the UPS delivery person brought the packages he asked what was in them and when I told him he wanted to know if I was going to ride in it! The kit came very well packed with no damage of any kind what so ever. The boxes appeared to have had a rough trip but the contents were fine.

After spending a few hours going over the parts list and drawings the only problems found were the servo mounting blocks were missing. A quick email to Dany at Genesis and they have arrived at my door step along with a revised manual, I have one of the first 10 kits produced! That’s service in my book, these guys are really out to make the consumer happy. As this is posted under User Product Reviews you cannot respond directly to this forum. If you have questions, comments or suggestions I have a thread open in Giant Scale, http://www.rcuniverse.com/showthread...483#post897281 please make you posts there and I will be notified and respond as soon as possible.[

On with the build. The first thing to do is set up and glue the top wing jig to your building surface. A little hint here, putting a few #64 rubber bands around J3 and J4, (the long pieces), makes it much easier to hold the jig together while you square it up and glue it down..

Once the jig is straight and square just stack the ribs in and glue down the top spars. If you have a rib that is not straight, watch the ply ones, just clamp a short straightedge on it before gluing the spars down.

Three hours latter, including the jig setup time, and you have the first of four panels framed up! So far there is nothing here to be intimidated by . One note, sheer webbing is only required on the L.E. Spar.

Pushrod02

My Feedback: (16)

Once you remove the wing panel from the jig and install the bottom spars the instruction manual has you install a couple hardwood webs between the spars at rib #8 for N-strut and flying wire attachment points. You then sandwich them between 1/8 ply as in the picture below.

Pushrod02

My Feedback: (16)

Next you are to put the metal attachment points on, DON’T do it yet. Once you put them on the top wing, it will no longer lay flat on the bench making it much harder to put the webbing on the front spars. They will also make building the ailerons much more difficult as you will soon see. Just don’t forget to come back and put them on before the wing sheeting goes on!

Even though “Murphy” caused as many interruptions today, (4/24), as possible, I managed to frame up the other top wing panel.

Sorry I've been gone so long, spring time seems to bring on lots of chores....of course a little time at the local field was also in order.

As you can see in post #5 the trailing edge is scored with the laser to locate the ailerons and a 1" spacer for their L.E. and T.E. Just glue up some 1/8 sheeting and cut the skins with the supplied templates. Line it up with the mark closest to the T.E. and glue them down.

Pushrod02

My Feedback: (16)

Cut the aileron away from the wing and your ready to put in the laser cut control horn blocking. Glue the two 1/2" blocks together and glue two rib 8. Now you have a place for your control horn hard point to mount.

Just to many irons in the fire this summer to get much building done but with a little prod from 2 Piece I did manage to get the ailerons built up for the top wing panels. I will be using the Robart 3/16” hinge points for my control surfaces. Before gluing on the ½” leading edge you need to add a ½” filler block inside for more surface area when gluing in the hinge points. Be sure and mark the location on the skins before attaching the leading edge.

Pushrod02

Don’t forget to mark the blocking for the control horn’s hard point too, seen here on the left.

Finally found a little time to build this weekend. Had to stop the house painting as it's been raining all weekend .

Remember the N-strut/flying wire attachment points I told you to leave off in Post #5? Well now you need to put them on permanently and use a thread sealer. This is your last chance to access the hardware for them, it's time for the L.E. skins.

Before you place the skins you strip a piece of 1/8"x 5/8" X48" and attach it to the notches for the sub leading edge. Use the supplied Master Airscrew balsa stripper for this. Put on the bottom skin first and glue it all down. I started with the L.E. and got it set with thin CA. Turn the panel over and start at one end and pull it up tight then hit it with the glue. Hint; cut four pieces of 3/4" plywood to rest the panels on, it makes them set solid with the hardware hanging out. You have to notch out the skins for the hardware and save the piece you cut out to fill in with.

Now do the top skin in the same manner. Get it sett along the LE with thin CA. This skin requires a bit more bending to pull it around the ribs so wet it with a rag dipped in water to soften the fibbers and it pulls right down. I weight it down and let it set for 15 minutes or so to start taking the shape. This gives you time to get one of your friends over to help glue it down.

We used medium CA for this step with the long squeeze bulb applicators to hit the ribs and top of the spars with. I get them at
http://www.balsapr.com/ for a couple bucks in a package of five. They're worth their weight in gold when you need to reach in somewhere to apply CA.

As you can see I left the sheeting edges run a little long to leave extra material to work with when your ready to mate up the wing panels to the cabana sections.

The bottom side of the T.E. gets sheeted from the aileron bay to the root rib next. Get out the balsa stripper and a 1/8 x 4" x 48" sheet of balsa. Strip the entire piece out 5/16" wide. This makes the cap strips and the T.E. strip for the top of the bottom skin. The bottom skin gets rounded at the root end and a template is provided.

Glue a 5/16" strip along the T.E. of the bottom skin. This will work as your guide for setting the bottom skin in place against the end of the ribs. The only sheeting for the top side T.E. is between ribs 1 & 2. Template #4 is provided for this but is to short, slight growing pain of having a first run kit I guess. No big deal just stretch it a little bit.

Once the skins are in place go ahead and cap out the ribs top and bottom

Now for the easy parts. Glue up the L.E. of the wing and have lots of clamps handy for this step. I used carpenters white glue for this, the kind with fibers in it, it gives you time to get it into position. Then put the T.E. on in the aileron bay. Both pieces are made of ½� X 2� stock.

you know, probably the thing I hate to do the most is leading edges.......and it is doubled obviously on a biplane

Pushrod02

My Feedback: (16)

CAPtain232,

Leading Edge and the mundane cap strips are truly a test of patience, The L.E. has been trimmed off but when you have to fit it up to a 2’ cabana it works better for me to shape it all at once.

“Warbirds over Pueblo�, fly in is this weekend in Pueblo Colorado so I don’t know how much more will get done this week. No War Birds in the hanger but I just have to be there! [sm=wink.gif]

Well, four wing panels, two cabanas, 14 oz. of CA and a little black cat hair gives you the wings. Been working on the last two wing panels and haven't taken time to post lately. The cabanas build just like the wings, in their own jig for setting up the ribs. Still have to sheet them and then it's on to the fuselage.

If you build this one, you better LOVE balsa dust!

Pushrod02

My Feedback: (16)

The bottom Cabane gets fully sheeted after you fit the wing panels. Nothing special here just get a good fit before you sheet them incase you need to pull a root rib one way or the other. The top cabane is not sheeted yet, you need the room to work on the struts once you frame up the "Box" portion of the fuselage.

The fuselage frame up is pretty straight forward. I used three hour epoxy to stick it all together. You will need every wood clamp you own plus a few from the neighbors. Clean the burn marks from the edges to be glued an clean out any epoxy from the factory glued side panels. Very handy to have the curve and ply laminates done for you in a press. This would not be fun at home [sm=disappointed.gif]. The frame all goes together at one time so dry fit , dry fit , dry fit! Make sure Everything is ready before you mix your glue and have a helper there to hand you the parts and hold things while you start the clamping process. It took about 2 1/2 oz. of epoxy and a hand full of micro balloons to put the box together. Give it 24 hours to cure and turn it loose. Get the 5' 8" tall wife to stand next to it while you promise not to post the pic on RCU, yeah right.

Happy Holidays one and all!

There has been a great deal more work done sense the above post but I haven't taken the time to post the pics. I'll try and get some up Friday night. Off to play Santa for a couple days.

Merry Christmas!

looks like Genesis made this Waco a good building aircraft, not like the Cap 232, which was a royal you know what to build, but makes up for building shortfalls in the air, a super flier, super stable with all the finesse I need and then some, thanks Dani........................................

looks great; can't wait to get mine!

Getting ready to start on my kit that I got almost 2 years ago when they were first available. Just had to many other projects in the fire and I usually do my bigger projects in the winter. Just got the engine for it for x-mas and boy is it a beauty. RCS 215 5 cylinder radial, this is one exceptional piece of machinery.
