Georgia Cracker (oz2321)
About this Plan
Georgia Cracker - Radio control sports model. 62in span vintage low winger designed for single to three channel RC operation. For .19-.35 engines. From the August 1967 edition of RCM.
Quote: "IF you've built every kit on the shelf of your local hobby shop and are beginning to repeat yourself, the GEORGIA CRACKER will make an excellent change of pace. Also, cutting out your own formers, ribs, etc from good-grained., warp-free Sig balsa will be a pleasure if you've had the same experience I have with some die-cut kits where apparently the job was done with mom's cookie cutter.
The CRACKER is a BIG airplane (span 62in) probably approaching the outer limits in size for single channel. But it has excellent flight characteristics and is very stable and forgiving of pilot error. With some wing modifications and a bigger engine, it could be made into a hairy multi job for the pros. Me, I like things calm and peaceful-like, as I am what they call a 'white-knuckle' flyer.
I would like to report that the CRACKER flew right off the drawing board like Lou Perretti's Gulf-Hawk (oz5520) from RCM April 1966, but a funny thing happened on the way to the Hall of Fame.
We decided on a hand launch for the first flight because the terrain was somewhat uneven. The Max 19 fired up co-operatively and my friend and trusted flying companion Bill Bell took off across the field as fast as his little bandy legs would carry him, brandishing the CRACKER like a fat javelin. Now Bill had never hand-launched a low-wing plane, especially one this big, and he failed to accurately compute the distance between the top of his head and the wing.
As a result, when he made the throw, his hat caught neatly on the left leading edge and the CRACKER took to the air as probably the first airplane in history to wear a white 6-7/8 Spinnaker hat.
Bill's lid was firmly lodged, and the big ship proscribed a quick arc to the ground, picking up a complete venturi load of gritty red Georgia clay. No serious damage, though, and soon the intrepid aviators are at it again, this time attempting an ROG.
With only a 19 (it really should have at least a 25) up front, the CRACKER is definitely not suited for carrier operation. Tail high, she rolled across the field ... and rolled and rolled and rolled. Power lines loomed, and I kept having flash backs of Jimmy Stewart trying to coax the overloaded Spirit of St Louis off that muddy runway. Finally, however, she broke ground, gained altitude rapidly, and I was off on a most gratifying flight. Smooth, sweeping turns (a little too smooth - had to add some area to the rudder), lazy 8's, some general field circling, and a bounce-free perfect landing, dead stick.
Those of you who are experts may be tempted to alter the design of the Cracker... less wing and stab area, etc. If you know what you're doing, be my guest. If not, my advice is don't mess with it. She flies just fine like she is, and the semi-scale appearance will be a conversation piece at any field... the wing is standard in every sense, with flat bottomed airfoil, planking along leading and trailing edges and cap strips on the ribs. The centre section is stressed to take the shock of landing..."

Previous scan version.
Did we get something wrong with these details about this plan (especially the datafile)?
That happens sometimes. You can help us fix it.

User commentsHi Steve, Herewith some photos of my Georgia Cracker finally completed [see more pics 006-009]. The Flag is of the State of Georgia as it was in 1967 when Walt Mitchell designed the model and the nose art is from a B-24 called the Georgia Peach. The next step is the flying, I’ll send some photos of that too. Regards from South Africa,

* Credit field
The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.
This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
