I added a piece of center sheeting and the leading edge sheeting on the top of the wing. I have to wait for it to dry before taking the wing out of the jig. I can't go much further as the red things are in the way of the bottom sheeting and spars. The bell crank is ready to install and I had ordered the wrong flap control horn, which is my usual M. O. I figured the upright had to move 3/4 to the left. I put it in the vise and leveled the horn with a line level. My trusty Bernz-O-Matic heated the braze and i slid the item to where it should be and added more braze to hold it. I filled the top hole with braze and re drilled it 1/16 as I want to use a clevis. I have some ply wood parts from the Legacy kit as I used fuselage mounted gear on it so I have all the parts needed to make wing mounted gear on this build.
I called Brodak and ordered the motor and stuff so that will keep the fuselage on the table until that arrives.

Flaps.
I made the hinge pockets on the flaps the same way I did for the wing trailing edge. I cut the flaps 3/4 short on the leading edge so the 3/4 strip with the hinge pockets would make them the right size when glued on.
One piece wing trailing edge.
I marked the location of the hinge pockets on both halves of the trailing edge and sanded the pocket into each half of the trailing edge. Then, using a straight edge, I aligned the halves and pinned them and opened up the pieces for glue. Pushing the parts against the straight edge I pushed them together. Then I marked the rib locations and made notches for them on the band saw. I had to taper the assembly from 3/8 at the front to 1/4 at the trailing edge using rods and a razor plane. After that I installed the trailing edge on the ribs and secured it in place ready for glue. The trailing edge sheeting will cover the assembly adding strength. I plan to install shear webs on the trailing edge sheeting and between the spars for a "D" tube structure.
The wing.
The wing is taking shape. As usual I didn't place the jig rod holes to my best advantage. The bottom spar can't be installed until the wing is removed from the jig. I have to get a sheet of 3/16 balsa for the trailing edge. It will be full length and laminated together to make it 3/8 x 1/2 with rib notches cut in and the hinge pockets sanded in to get them perfectly centered.

Brodak to the rescue.
The laser cut Legacy ribs came in today. I poked the rod holes in each one and had to tape the cutouts in place. I've been using the Adjusto-Jig for 30 years or more. I've found the fastest way to set the red things for the proper rib spacing is to measure the spacing on the plans and subtract the width of one of the red things, in this case 3/8". Then I cut pieces of corrugated cardboard to that dimension, in this case 2 1/8 minus 3/8 equals 1 3/4". Then I set the center rib spacing on each side and using the cardboard pieces place one between each of the red things. Making sure the cardboard is touching the pipe and not riding up into the red thing. A measurement makes sure it's right.
The 45 degree bias balsa sandwich is curing and I'll use that to beef up the nose. Probably use a piece of lite ply over it on the outboard side.
I included a picture of Nomads one and two so you can see what I'm doing. I have a third one the same size and a larger one with the Pattern Master wing. LA .46 power on the three and .52 or .60 on the bigger one.

Newest Nomad.
I have a Nomad of this size already but it's wing is a foam core Pattern Master wing. All my other Nomads use the Legacy 40 wing with a slight re-design. The other day i got the idea to see if Brodak has wing ribs for the larger Legacy and they do. i started to draw out the front end of the fuselage on a piece of 1/2 inch balsa and then got the idea to use electric instead of a normal engine. Mainly because I couldn't find the engine I wanted. All rear exhaust or too much money. I have batteries and a timer already.
The ribs should be here in a few days and I have stuff to build it with wing mounted gear as I used fuselage mounted gear on the Legacy itself. Now I need to get with Brodak and buy a motor and ESC.
So far I have the stab/elev built and some balsa. I'm finding other parts for the plane as I go. Too bad I didn't find them before ordering more from Brodak. I got the motor box kit from Allan Perret's collection.

It's in the books.
Contestants started arriving on Thursday. They started flying right away to get a feel for the park. On Friday more arrived and the park people had the field mowed. I got down to setting the circles with the help of an expert in these matters who came from Atlanta, Ga. Around noon we had the field set up ready for competition. I had borrowed 3 tables from the park and with the clubs tables we had enough. Saturday I got there as early as I could after making two jugs of coffee. After everyone signed up and the score boards were set the competition started. The winds were tricky and there was only one plane crash that didn't make sense. Two others were attributed to pilot error.
I had reserved a room at Big Mike's for 6:00 pm and we got there about quarter of only to be late. The rest of the folks were already there. We upped the amount of attendees to 30 and that was how many we had. I passed out the days awards after everyone had finished eating and then a birthday cake was brought in for two guys who's birthdays were that day and the next day. The usual trick candle and the cake was good.
Sunday was as forecast, cool, windy and showers. I waited for the others to arrive and we had the raffle and called it a day.
I had hoped for 10 contestants and got 11. 3 of which I consider influential people. So they will be believed when asked how the contest went and how is the park for flying. The club came out in the black by $40.00 after paying all the bills. So it was a success.
While the raffle was going on I got all the stakes pulled up and caution ribbon taken in and disposed of. the trash I put in bags and took that to the dumpster so the park people could do their jobs and not mine. Monday morning I took the tables back and the carnival trucks were already arriving. Then We took all the clubs stuff I rescued from the smashed trailer back to the good trailer in Zachary. Then I went flying.
