I’ve been looking at the Hustler too and wondering why it needs all those ribs. The nostalgia rules allow you to add or subtract ribs as you scale up or down, but what if you are building it the same size. In the article that was in the NFFS Digest when the Hustler was approved, Dave Edmondson said that the rib spacing was reduced from 1-1/2″ to one inch to add more weight for FAI. It would make a lot more sense to build it with 1-1/2″ rib spacing, if that’s legal. Sid Jepson used a jig saw to cut the front fuselage outline out of 3/8 plywood. He cut is so it’s about a quarter inch all round, so maybe it’s not that heavy, but I would build a balsa outline.01/18/2016 at 7:59 pm #55763SIMON BLAKEParticipant
I fly a 600 T-Bird which was originally built from a BMJR kit. It’s based on the original 600 version and has an under cambered airfoil. Most people flying a 600 use a scaled up version of the 1/2-A which has a flat bottom airfoil and that’s what I would do if I was to do it again.
I had a lot of trouble with the wing design on the BMJR version. It has spars that go through the centre of the ribs. The plans recommend reinforcing the spars with carbon fibre, which I don’t think is legal in nostalgia, or using spruce spars which is what I did. However, even though the wing was covered in polyspan, it was quite flexible. With an OS. 29, at a certain speed in the climb the tips would wash out and send the model into a dive.
I saw two others do that at the last Muncie SAM Champs. So, I built a new wing where I basically split the spars — the front are 1/4 sq. and the rear are 3/16 — located in the same location on the wing but top and bottom with webbing in between, and now I have a really rigid wing that is 2-1/2 ounces lighter than the original. And now it flies pretty good with the .29 in Class B and a Torpedo 32 for Class C.01/23/2016 at 7:36 pm #55764

Now that is something different. Looks complicated!
John01/24/2016 at 3:01 am #55766
I like Wild Blue too(jim ORielly)…That would be a hard little sucker to build…but great look….
DDock01/24/2016 at 5:06 pm #55767Nigel TarvinParticipant
Salt Lake City Sadie. I just have to get around to covering it! 🙄
01/24/2016 at 11:29 pm #55768
That’s a beautiful plane. Let’s see it finished.
A bit above my patience and building skill level.

Bob Deshields has a 900 sq. in. Zero for a O.S.Max 35 it should weigh 37 ozs. it just needs covering and trim it was enlarged from the 1/2a plan

I’ve had decent results with Stan Hill’s Amazoom. Easy to build and trim. Published in the Nov 1955 MAN as a FAI model. The original plan has scaling factors for four different sizes including 1/2 A so it can be built as an early 1/2A. I currently have four, 1/4A (BMJR), Early 1/2 A (Cub), original 400 (Green head), 500 sq in(OS 15 III). Klarich has a 600 sq in Zero short kit scaled from the 1/2 A.

Found a few more for you…Just depends on how brave you are:
All of these are on the Volar Libremente web site.
Southern Belle…1956…Round tip Amazon type
Hi Fli…Phil Kraft…I have seen a couple of these go real good.Fairly easy to build
Raunchy…George Perryman (from rubber fame)1953…Would be interesting scaled up
Little Giant….1954…high thrust pusher
Elf Axe…1949…Stab on the bottom can be difficult
Konkerer…1952…high thrust pusher payload…Build for Rudy’s Nostalgia Payload event
There you go…Have fun

I liked the look of the “Hot Head” http://www.jimoreillymodelplans.com/NOS24-NOS28.htm
Norm01/30/2016 at 3:44 am #55773
Thanks for all the tips. I have either downloaded or ordered the plans mentioned. Quite a few choices!
John01/30/2016 at 8:59 am #55774Peter TolhurstParticipant
In case you’ve not seen it, another one I like is Dick Mathis’ ‘Jalapena’, and you can download the plan & build article here:
So much to build, so little time
Peter01/30/2016 at 4:27 pm #55775
That looks like a neat airplane to build. The fuselage also looks ready to break right at the end of the pylon upon a DT landing, considering the force created when the under slung fin hits.
Unfortunately, it isn’t listed in the NFFS Nostalgia eligible list or I would build one.
This is a great discussion.
John01/30/2016 at 9:20 pm #55776DAN BERRYParticipant
Jalapena isn’t a Nostalgia design.
A side note: It’s a pretty thin airfoil.
Gene smith has one with a VA 049. It is very fast. Plastic covering wasn’t up to the job. It now has tissue over the plastic.
