Fuselage construction is easy because Gunny has designed the building process in a way that allows for most of the fuselage construction to be done on a flat surface.
First step is to layout the plans and make a jig to bend the base stringers around. Remember, these can't stick up above the longerons or get glued to the floor that is added to them.
Gunny provides triangles to set the correct angle of the formers.
Several of the main formers are laminated to add strength.

More on the tail feathers...moving to the horizontal stab and elevator. The rounded ends are laminations of plywood and balsa.

signed on JIm! so you switched from green to blue tape on the TE sand down and also a different lighter sandpaper on final I presume...Is the green tape different for a special purpose? .... thinner maybe for finer fit?

That's great...you can help push me along in the build!
Gunny and Erich had their 1/3-scale 2-33's at the Windy Ridge Event in Hammondsport, NY in June, 2016. We did some side-by-side towing and then they did some formation flight and mild aerobatics...absolutely picture perfect visual art performance.
Jeff D took amazing pictures which can be seen here: https://www.flickr.com/photos/jd-xti...54447656/page3

Jim,
I just bought one. I am not quit ready to build it yet, but want to have one on hand in case Gunny stop making it. Just ordered the spruce from Aircraft Spruce and Specialty. Still need to collect all the flat sheet stock.
I will be check on this thread.

If you want your very own Aviation Concepts 1/3-scale Schweizer SGS 2-33A, it is available direct from Gunny.
You can also get Erich's scale tow release and the addendum parts kit direct from Gunny.
Check out Gunny's complete website/store at www.AviationConcepts.com

The 1/3-scale model kit arrives in a 12' x 12" x 36" box that is quite heavy. When you open it up, the amount of stuff that Gunny has packed in such a small space is truly amazing!
First thing is to locate the full color manual for intricate step-by-step instructions that no other kit comes close to matching.
Unrolling the multiple sheets of full size planes is another treat...every sheet has color print and is embossed with an Aviation Concepts seal.
The many sheets of parts are beautifully precision laser cut. Even has this neat detail on one of them.
And each kit has a serial number, I got kit #003
I had purchased this scale tow release mechanism that Erich Schlitzkus makes...
...and Gunny has an addendum kit that outlines the modifications and air-frame parts needed to mount this mechaism.

Aviation Concepts 1/3-scale Schweizer 2-33 ~ Build Thread by JimD
I met Gunny Bumburs at the RC Propbusters New England Aerotow in 2010. It was the first time we both attended the event and ironically, we were the first two to arrive at the field on that first day of the event. Gunny brought out his 1/4-scale Schweizer 2-33 and I was immediately smitten. As the event unfolded, the Schweizer impressed a lot of the other attendees and Gunny was awarded the Best in Show award. This photo of Gunny with his award and 2-33 model has additional significance for me because of the Pilatus Porter in the background (but that is another story!).
The 2010 New England event was held in September (has since been moved to May) and my Fall Soar for Fun was coming up in two months. I persuaded Gunny to attend by buying a 1/4-scale kit and promising him a steak au poivre dinner at Fratelli's if he delivered the kit to Cumberland. Well, he did just that and can be seen (on right) with his 2-33 in this photo from that event.
So we built the 1/4-scale 2-33 and were happy...until we got to see Gunny's 1/3-scale 2-33 at the 2014 Cumberland Summer Soaring event...oh well, had to give Gunny more money! Here are a gaggle of Gunny's Schweizer 2-33 models at the 2014 Summer Soaring event along with his brand new 1/3-scale model.
Gunny's 1/4-scale is third from the left and his 1/3-scale is on the far right.
I promised Jason Haab that I would encourage his 1/4-scale build by posting my 1/3-scale build to help pull him along, so here goes!
