GIANT EXTRA 300 2.8 meter w/span PDF PLANS 100-150CC

Up for grabs is a pdf version of a giant scale EXRTA 300 plan on cd. its designed for 100 to 150 cc petrol/gas engines,

the wing span is 2820mm nearly 3 meters, have a read of the discription below for all the deatils, it is of 5 sheets and in dxf, dwg and pdf versions, this means you could pass the dxf and dwg on to a cnc cutter, to save you time in buildings, it has a foam wing so you can pass the dxf and dwg on to a faom wing cutter if you dont cut wings your self, its a high quality plan, its not to detailed on building as only an experinced buidler would attempt such a project and would know how to construct this giant aircraft.

this aircraft is constructed from balsa, ply and spruce for the fuselage and foam for wing and tail feathers

each of the 5 sheets measures 108'' x 36'',

the notes on the plans are in german ( i think). specification sheet is in english

also you will get a specification sheet most of the details are shown here below

THE PROJECT - EXTRA300s 3W120

This model plane project, was made under the rules of (F3AL) class from FAI - FÉDÉRATION AÉRONAUTIQUE INTERNATIONALE - Switzerland, and utilize balsa, plywood, Styrofoam in the wings and stabilizer; fibreglass in the engine cowl and wheel pants. The construction is conventional, and the finish process is made with the plastic film cover with hot iron and hot gun. This project is fine-tuned and tweaked to excel in both precision aerobatics and wild freestyle type D, as specified in the TOC, so doing any aerobatics with this model airplane will be easier. Please pay particular attention to the seal of the aileron and elevator hinge gaps, on large aerobatic models, this is absolutely necessary. Follow the control horn and servo arm lengths recommended in the drawings, shorter arms on the servo or longer control horns on the elevator and ailerons to avoid flutter. When flying aerobatics with a model of this size, you will find that it will do everything just like a smaller model, only better and easier, BUT you have to throttle back to idle when the nose is pointed down to preserve the structural integrity of the airframe. Please don't misunderstand the purpose of these paragraph, if you take reasonable care, big model flying is a highly creative, instructive, enjoyable and relaxing part of this hobby.

RADIO EQUIPMENT

Although a computer radio is not mandatory, it is preferable in this model, to adjust Exponential on all controls to soften the feel around neutral.

1. Six (6)-channel computer radio system (minimum).

2. Two (2) standard servo (FUTABA S9152 or equivalent), for throttle and smoke system.

3. Six (6) hi-torque servos, metal gear, water protected, (FUTABA S5050 or equivalent), 2 for rudder, 2 for ailerons (one for each), 2 for elevator (one for each half).The servos used for the control surfaces must have a minimum of (180-ounce / inch) of servo torque and need to be water protected, because they are externally installed.
