Hi my name is Bryan and am a spritely 72yr old from Australia. I have just recently joined this group having purchased a set of J1-B plans which I hope to...
Hi, Bryan. I wish we had heard from you sooner. I have a set of J1-B plans for sale. listed on the Janowski Yahoo Group. They are a few months old, unused. ...
Hi Brian, I dont know of any J1B guys down under but I have always thought the plane would be an excellent candidate for rivited sheet metal construction. Good...
If you have the time and want to use a metel spar the best and strongest system is the one they use on the BD-4. It is very simple and strong. A wing using...
The tube spar used on the BD4 is not the best because it is very heavy for the strength supplied compared to an I-Beam spar layout. I admit that the BD-4 was a...
Wow! Someone else knows about BD-4 wing spars?!? By the way, Mr. Bede originally designed that spar for use on the Grumman line of low wing aircraft (when...
Stephen, can you provide us with some photos of the shell that the molds produce or finished airplanes from it so we can see? Thanks Scott ... A guy at our...
This design concept is a compromise because a tube is actually not a very efficient spar shape, from a weight perspective. The rectangular shape spar can...
Parhaps you are right... Just looked over the plans and found very confusing things.... the buckheads made from 10 mm plywod!!!!! Do not understand why... they...
I think you misunderstood my reply. I said that the wing 'SYSTEM' was good and would suit the J1-B. The photo's are of a wing in Australia and are not off a...
I am sure Scott understood absolutely correctly; the BD-4 SYSTEM is not much suitable for J1B as an economical by sense of weight if compare to a classic box...
Unfortunately you will no longer be able to access the VULA site. I spoke to the site owner and he had lost all the information through a virus and he said it...
About three months ago I posted my J1-B plans for sale. I am lowering the price for them to $45. I also have the plans, Spruce, plywood, and some parts for a...
I have been studying some old composite airplane designs ** and I am convinced that the J1-B fuselage could easily be built with composite foam sandwich slabs...
Scott; The original plans had the foam/fiberglass dimension along with the wood layout. I am working on a .040 6061-T6 angle (from sheet stock) riveted version...
I thought the foam fiberglass info was just for the wings ? ? ? By original, do you mean the metric version plans ? The angle and fabric cover idea seems...
Scott; I guess the American-ized plans had the RFP dimension on them. Curves are formed with a shrinker/stretcher so that the curves are maintained as per...
Let me clarify, you have a set of plans that specify dimensions for the foam components to build the fuselage out of composite instead of wood ? ? ? Scott...
Scott, I have thought this very same thing for a long time now. It would be cool to see an amphibian version of the J-1B. I thought someone was actually...
soy nuevo en el grupo hola a todo el foro. busco para construccion desde planos algo como el quixote pero de 2 plazas, alguien me podia decir que aviones ahy. ...
see the attached pics of a 1400 pound 200 mph composite plane fuselage (the Polliwagen) being built. Tell me that doesnt look a lot like a boat ? I am...
Hi to all, I'm in the process of building a mould of the fuselage to build the J-1B in composie, with very little foam in it. Because the fuselage is mostly...
I am new to the group hello to all the forum. looking for something like building from plans Quixote, but the 2 places, someone I could that aircraft ahy. ...
NO NO NO. Please stop. Are you making a separate float to put the plane on top of ? I just now saw your drawing. That will result in way too much extra...
