Thanks Tom.  The washer is punched out of scrap plastic with a garden-variety hole punch.

Mike, she looks great.  Thanks for the pictures of the washer and screw.  Is the washer something you make or is it bought?

Working my way through all the fiddly bits.

For AK, here's some pictures of the stab adjuster retaining washer.  Slips over the threads, turns with the screw, holds the stab against the head of the screw.

Turned a spinner from blue foam, and a replacement tailwheel from foam as well.  Came out a bit lighter than the coarser black foam I used before, and takes paint much better.  Final tailwheel weight is .26g

I built up a prop following the method shown in Tom Hallman's video here:  https://www.youtube.com/watch?v=PUajqbTIARM.  It's about 1.5 grams lighter than a 7" Peck prop and has higher pitch, but I'm not sure I've got a good blade shape.  We'll see how it does and how it holds up.

Intent is to fly the model tomorrow at our monthly meet-up.  I won't get everything done before then - will have to add antennas, control horns, lights etc after initial trimming.

Mike, did you state that you were using regular 20# copier paper or hard card stock for the wind screen and side board?

I just noticed your landing gear. How did you make them?


Bob,  I used 16lb copier paper (HP sells it as "Ecoficient" paper) for the window templates - every little bit of weight savings helps...  The landing gear struts are two layers of 1/32" balsa laminated around a foam template.  I used one of AK's mini-diamond files to cut a channel in the underside of the struts for the landing gear wire.

The Waco is coming along quick, and looks great.  If you have trouble with aligning the wings you could try making a foam jig like in post 199 here:  https://www.hippocketaeronautics.com/hpa_forum/index.php?topic=21454.175

OK! here is the scary part for me. Struts and alignment.

Just test fitting for now. I cannot attach the struts until everything is covered and the wings are glued to the fuselage.

Tom, I have been building continuosly, but not posting much. I know about life issues. The son has been taking up most of my thoughts.

As for the Waco. I am not sure the photos show all. Ive been learning so much and looking back at everyone's builds here and in the past To learn as much as possible since this Waco is out of my comfort zone.

Mike, did you state that you were using regular 20# copier paper or hard card stock for the wind screen and side board?

Ian, the bones are looking good.

Mike, thanks for the photos re: windows. You fixed my problem for the Waco. I could not figure out how to install the side glass. Now Ive got a place to start.

Waco bones:

Good-looking bones, Ian, and quite light.

Progress on the Broussard has been a bit slow - just haven't been fired up to finish it.  I did put in a few hours here and there to get the glazing done.  Paper templates for the windows, covered with tissue attached with spray adhesive.  Glazing is lightweight clear gift wrap plastic.  Not many excuses left, going to have to mount the wing.

I have done a bit on and off. I moved the rear peg placement forward by one bay. Then I cut back the material aft of that point to reduce the weight near the tail. At the moment, the weight of all components less the LG is 7.9 g.

Craig, those wheel pants and cowl have raised the bar. I now need to work cleaner, sand more, and take my time.

GREAT JOB!

Nice shiny wood...what did you seal it with? Did you sand it between coats?  Looks fantastic!

I love a good "bones shot" as well as the next guy, but a disarticulated skeleton is as good as this one gets- it doesn't lend itself to an easy dry assembly  Sad 123.25 in/sq WSA- 26.67 g as pictured. There's no wire in the LG, but I have it on good authority that all those Fairchild struts impart a lot of load-spreading. I think the bottom longerons are probably going to get some reinforcement at the gear/strut mount area before the covering starts, which is likely to happen as soon as I refine a windshield template.
