Electric Chaos (oz10621)
About this Plan
Electric Chaos. Radio control sport pattern model, for electric power using Speed 400 motor. Wingspan 46 in, wing area 350 sq in.
Quote: "A park flyer that's a fully aerobatic pattern aircraft with excellent low speed handling during landings. Electric Chaos, by Robert Larson.
The Electric Chaos borrows a great deal from its predecessor the Utter Kaos, a legacy pattern aircraft designed by Joe Bridi, using the construction techniques of the Electric Kitten designed by Fred Reese. With the encouragement of both of these great model designers, the Electric Chaos became a reality. Having just built the Electric Kitten by Fred Reese, an outstanding high wing Speed 400 Park Flyer, which I would highly recommend, I was ready for full-house performance using the Speed 400 motor.
I flew the model the first time with an 8 x 6 APC Slow Flyer prop, a Speed 400 6 volt motor with the Mini Olympus gearbox from Hobby Lobby, using a 7-cell KR600 AE battery pack with Deans Ultra connectors from EMSJomar, which gave 6-1/2 to 10-minute flights.
The plane is about three quarter size of the Utter Kaos, with the fuselage length reduced to cut drag. The wing is almost symmetrical, but for ease of construction, it is flat on the bottom, from the spar to the trailing edge.
The model flew well, with no trim adjustments needed, take-off was smooth and straight and lifted off in about 30 feet. I did Rolls, Loops and some Hammerheads on the first flight.
The prototype Electric Chaos' finished weight was approximately 20 oz, giving a wing loading of only 7.4 oz/sq ft.
Construction. Assembly Note: A variety of 'ZAP' CA products were used for the construction of this model and are called out in the text.
Fuselage. Lay waxed paper over the plans, then pin down the top fuselage 1/8 in longeron. Do not pin through the wood, but rather place pins on both sides. To save time cut two of each upright and diagonal 1/8 sq sticks. The second stick for the second side. Pin the bottom longeron in place and glue in all of the uprights and diagonals. When the first side is finished, pull out all of the pins. The side will still be lightly stuck to the waxed paper. Lay a second piece of waxed paper over the completed side and replace some of the pins. Build the second side directly over the first. When complete, separate the two sides and add the 1/16 in balsa gussets to support the landing gear. Add the 1/8 in sq servo rail supports to each side.
Bind the 1/16 wire landing gear to F-2 with thread or fine wire. Using the top view of the plan as a guide, lightly glue F-2 in place between the sides. When correctly aligned, re-glue F-2 with medium CA. Pull the sides together at the tail and secure with a rubber band. Secure F1 in place with a rubber band. Adjust the rubber band tension until the fuselage is straight, then glue Fl to the frame.
Before proceeding, check the fuselage for straightness. Glue the fuselage at the tail. If necessary, crack any glue joint, make shift and re-glue. Glue in the rest of the top and bottom crosspieces. Add the top 1/16 balsa sheet, but do not glue on the bottom sheeting until after the wing is fitted and the mounting dowels installed. Glue in the 1/16 balsa sheet between the stringers at the rear for the fin and sub-fin support. Glue in the 1/16 balsa at rear sides for lead out exits..."

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

* 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.
