The section just behing the cockpit to the tail feathers, on a nieuport it's the shape of a cone. The rear portion of the fusalage.
Knuckle got my drift.........It's really a better solution to go with the harder wood there.
GO GAS< GO NITRO 4 cycle, Sound is good. The weight will still need to go in the front. It's on either side of the firewall rounded on the outside edges to the shape of the fusalage. If your not going to scale competition and don't care about a zenoah engine showing thru that nice aluminium cowling. It's no big deal......BUT ELECTRIC WW I ..........Oh Nooooo. what's this world coming too !!!.

Due to weight I will most likely go with balsa fuselage stringers but I can see how they would easily be broken. For the most part the people at my field never pickup my planes. The fragility of the stringers should not be a problem.
Think of electric as some advanced type of Gnome rotary motor and it will ease the pain!

If somebody pokes a hole in the rear fuselage, Just cover it and call it a rear Hatch!

Amusing as it sounds, did you see the hatch on Denis' plane..... Right where mine is!
For those that don't know.... My SuperCub got a hole in the fuselage about half way between the wing and the tail, on the right side. Now it has a custom hatch where the hole was.

Some pictures of the 28 that was in Arizona. The whole collection was purchased by the software guy and moved to the museum in Seattle. A must see.

Sun, I got the numbers for you, Engine 3 * degrees down, Lower wing + 2* degrees, Top Wing - 1/2 * degree,
and the Stab ended up at + 3 * degrees. This airplane fly's very well. with all the numbers given. Of course your building habits
C G, may differ. I have a good amount of lead on the firewall to balance.

I know this is late (along with many other posts), but I saw a post mentioning not having to move the firewall because of the position of a side mounted carb. It is not necessary to move the firewall if a hole is cut in the firewall itself so the carb can protrude through it. I am assuming this would be a rear carb.
Also, I vote for gas all the way. Even beyond that, I would put a Mag G38 on it! I like the mag engines as they work all the time without the extra battery. Then, you will not have to worry about tail heavy especially if yuo build the tail light.
Another point, use a 1/4" music wire axel. This will save you the hassle of replacing the smaller stock axel later on.

This is a great flying airplane. I have been flying mine for 3 yrs. Saito 150 no problems or big mishaps. I used small bungee on the landing gear cross member and works perfectly.

Sun,
Top wing incidence was to keep it flying longer than the lower wing in a near stall attitude. This from the master builder from a talk with him today at Top Gun......

It's interesting that you would want the bottom wing to stall first. The "typical" setup for a biplane is to have the top wing stall first. This has the effect of moving the center of pressure rearward along the wing chords and causes the nose to drop therefore recovering from the stall. The idea is that if the lower wing were to stall first the opposite effect would occur...the CP moves forward pitching the nose up and thus entering a deeper stall. However, practical experience trumps theory, and if your plane flys well, what more could you ask?
BTW, based on recommendations here, I cut a bunch of 3/16" square hardwood stringers and started installing them today. I compared the weight of the balsa vs the hardwood (pine) and found that each pine stringer weighed approximately twice as much as the balsa ones...6 grams vs 3 grams. I estimate that this will add about 2 ounces to the tail of the plane.

RE: Balsa USA 1/4 Scale Nieuport 28 Build
im in the final stages of my busa n28 and have gone with the g26 aswell. when i laid out the mounting location it looked as though the velosity stack was going to interfere with the cowl. any suggestions? can i operate the engine without the stack? i'm worried the i might get spitting if i dont use it. i would appriciate any guidance.thx.

Red Wing, if your not going for the ultra scale look cut a hole for the velocity stack and you can choke your g26 with your thumb in the stack.

This morning I was going through some of my photographs and I found several of a 1/4 Scale Balsa USA Nieuport 28 flown at one of our local events, the 2010 Gunsmoke scale qualifier. I believe the pilots / builders name is Rick.
Building on the left wing half will begin shortly, just finishing my morning coffee which is not an optional part of the morning.

In preparation of building the other wing half I double checked the plans, which are a separate piece of paper, and the plans do not match. The wing half I already build is about 1/2" longer than the plans on for the left wing half. As you can see in the photos the rib spacing also starts to deviate (Photo is the right wing panel laid over the left wing plan). This should not be much of a problem. My plan is to build the wing right on the table, using some hand drawn reference marks on the table from the first wing. Somewhat disappointing the plans don't match in scale but not totally unexpected.

Construction of the upper left wing panel begins. I used the first wing half as a guide, marked the table with a grid following the rib spacing of the first panel, and started gluing things up. It took a little while to get it drawn out but progress is being made. Now that it has started the wing should progress the same as the previous.
As you can see in the last few photos the ribs now line up as they should.

Left panel got it's wing tip and upper spars... Just waiting for that to dry then I'll install the sub-leading edge. Sheeting will begin tomorrow.
I also installed a fence onto my bandsaw. The fence should allow me to rip down small strips of balsa. For sheeting I use the table saw but the bandsaw is great for thin strips.

Bottom sheeting being glued to the main spar. After the glue dries the wing will be flipped over, weighted down onto my table to keep it flat, then the sheeting will be bent upwards and attached to the leading edge and ribs.
Second half is a little easier than the first. All is going well.

I didn't get a lot accomplished this weekend but I did get the most time consuming part done. For me sheeting the wings takes a bit of time. Because I am using regular wood glue I must clamp the parts up and let them dry. For the top wings, this process is complete. I need to add the cap strips to the left wing, add the leading edge, then sand the leading edges of both wing halves. After that the halves will be joined into one piece.
Then onto the lower wing.
I compared the two wing panels but stacking them on each other and they match perfect. I am glad I caught the mismatch in the plans.

If you read enough BUSA build threads you will hear of this problem quite often. My Super Cub plans have problems and the DR1 had issues as well.
