hi all!
first at all, i wish send a BIG thanks to Mr Steve Fauble (faif2d).He send this amazing kit  to me.Iam honored and hope do a good job with this model. THANKS STEVE! here is the build  as you wish.


Impressive box.Is big...really BIG for ff scale model.no color pictures, only the top box ilustration. a very colpete plan, looks older!
the wood selection is good.some holes for lost weight i think.need to study when cut holes.
is complicated build, iam study the plans for 2 weeks.still need look again some parts.
following the instructions, i start step by step.
first building separating pieces as indicated, in preparation for the build.

all here and there tell me: is complicated model very inestable in flight. is pilots killer!!.

but i take the chance to build it!
this is the first set of pictures, i post step by step the build.
comments, helps, suggestions are welcome! Grin

There is no color variation on the R1/R2 model.  Two were built, both red and white:  #7 and #11.  There were differences in the cowl and possibly the wing.

The City of Springfield is the model Z.

I have not seen a Jumbo Gee Bee R, but I have seen smaller and they fly better than you expect them to fly - not bad flyers.

A man out in the north west Delmar Benjamin has built a very accurate replica that he flies on the airshow circuit.  He does all sorts of aerobatics including knife edge flight.  I seem to remember that there is a aileron reversal at landing speeds or something but the plane is said to fly quite well.  It has been theorized that the level of pilot skills required was quite high and that most of the pilots of the day were just not up to the challenge.  I remember when a RC model of the plane was built Jimmie Doolittle was contacted and that the RC handled just like he remembered and told the model pilot.  There was only the one color scheme with the numbers 7 and 11 as stated.  One had a smaller motor and was to fly the cross country race and the other the closed course race.

Didn't Delmarre change the wing incidencs or washout?  I know it was one or the other.  Made the plane an entirely different flying machine if I remember right.

I had always been told the CG was off on the originals. When the repro was done the CG had been moved and thats when the plane acted right

I saw the plane at Oshkosh 13 years ago and bought Delmar's book. I devoured it that night at the motel, but couldn't quite get the picture of how its strange aileron rig worked (there were no photos of it, just text). I went back the next day and asked if I had it right and was invited to go into the plane and see for myself how it worked. I wasn't about to try to get inside, but I played with the stick a bit and saw that, as I surmised, it had enormous aileron differential.

I should have asked how he coped with inverted flight, but I was just glowing from my close contact with this magnificent machine, and my head wasn't working right.

I didn't wash my left hand for a month.

Great story Art!
Must be great to be that close to such a special machine.

Marcelop, great project! I will follow closely. I printed several plans of this plane but didn't start yet. Your build could give the needed kick to start it.
A GeeBee cookup would be great.... Ah... just not enough time...  :'(

We are busy with the organization of a large aviation event here, I hope to have time to build the Gee Bee too!.
In my next post I will put up the full details of the model and measures.
This plane is surrounded by an incredible atmosphere of air racing stories and legendary names like Jimmy Doolittle for example, and this particular model has attracted my attention, I'll try to do my best work here, although many I have said it is a very difficult model to calibrate and fly.
With exception of the hood, the model looks pretty light, but the hood is another thing, the design has two sheets of balsa 1/8, this looks very heavy, maybe I should make holes around the center to lighten these pieces, the system of "crankcase" looks heavy but this piece is also vital to the hood assembly as designed by Gene Dubois.
The fuselaje is a classic design “box” structure with patterns glued arround it, to do an circular shape at the fuse.
The root of wings have several blocks of soft balsa with the recommendation”hollowed all”.
The wings have no problem, need to watch the landing gear in detail is multi-piece part to work.

Marcelo, as short as the nose is you will probably have to add weight to it even with the almost solid nose structure.  I seem to remember that all of their planes used the same wing size and shape. I have no doubt that you will do the kit justice.

We have an R-1 here in San Diego. I took some pics with my Parkzone UM Gee Bee. If you need some specific pic, I will see what I can do about getting back to the museum.

I believe that  D Benjamin make a clear and public, point of changing /improving... Nothing! ...as then it would NOT be a Gee Bee.. but merely a bastardized  imitation.

Sorry Fred but thats incorrect.  He did make a few changes.  I just can't remember which one specifically.  I had the book he wrote about the build and he definitely made a change to the wing....wash-out or incidence.  Just too old to remember! LOL

No Mate.. Have the book in hand, even met Delmar, years ago when he first brought the R1 out on the Show circuit.
As the R1 had a inflight adjustable Stab incidence .. No actual need to dick with Pete Miller's design.
Which to restate again: he refused to do, as then it Would Not be an R1.. would it ?
Only change was an operable Canopy.. for obvious safety reasons

Hi All here!
Iam working a little this past week in the Gee Bee.
50 pieces need to assembly first after start work! In the set of picts, you can see the bulkheads of the rudder, this is detachable for better access to the rubber, the horizontal stabilizer is detachable too!, this is slided into recess hole.
As you can see the plan pict., the two bulkheads glued, is preparing to receive the wings center spars, in picture you see the spar example slided into recess formed.
The cowl rings 1,2, and 3 is glued togheter but do not shaped, as I read I building instruccions, nothing is shaped until not start the work.
The landing gear is assembled with several parts, the part showing in pict. Is from the outside panels of the pantes with the ply reinforcements.3.. ply outside and a flat 1mm ply inside pants! To allocate aluminium tuber for steel wheels axle.
All looks heavym but nothing is sanded and/or shaped yet.i presume the weight is reduced very much when the pieces are redy to mount in the plane!

Regards.
Marcelo pricoli

You are doing a wonderful job.  Seeing your hand holding the cowl pieces reminded me of just how large the fuselage actually is.  Have fun my friend!

hey! hello again!, very thanks for the decal set! i print onto esaky as soon!, , iam back to the GeeBee build,  Cheesy, iam finished preparing the second indoor meeting in my city, all the organization is maded by  of JV44 School !!! and start separate time for the builds!.

Made the wheels cylinders, with 3 laminated sandwich 1/8 hard balsa wood, and make the center hole for the axle....free wheeling very good.
start cutting the wing tips, and the front/rear pieces for the cranckase.all parts must be carefully beveled to fit into a geometric figure called nonagon, a nine-sided regular polygon.
the picture shows the amount of pieces need to pre-build first, the model is NO in the table-work yet! Tongue Tongue Tongue.
iam reading carefully for no forget oieces to pre-build.
