Using the Manual

Be sure to read each step thoroughly before you start 

the step. Test-fit the parts together to make sure they 

fit properly. If necessary trim to fit.

Beside each step you will notice a check box (or two). 

These are so you can keep track of your progress 

while building your kit. For steps that have two boxes, 

as in the construction of the left and right wing halves, 

these steps must be performed two times.

• Your 

Old School Model Works

 aircraft should not be 

considered a toy, but rather a sophisticated, working 

model that functions very much like a full-size airplane. 

Because of its performance capabilities, this model, if not 

assembled and operated correctly, could possibly cause 

injury to yourself or spectators, and damage to property.

• You must assemble this model according to the 

instructions. Do not alter or modify this model, as doing 

so may result in an unsafe or un-flyable model. In a few 

cases the instructions may differ slightly from the photos. 

In those instances the written instructions should be 

considered as correct.

•  You must take time to build straight, true and strong.

• You must use a R/C radio system that is in first-

class condition, a correctly sized power system and 

components (electronics, batteries, wheels, etc.) 

throughout the building process.

•  You must correctly install all R/C and other components 

so that the model operates correctly on the ground 

and in the air. (Installation shown in the manual is a 

suggestion. You may have to adjust the mounting steps 

to accommodate the size of your radio equipment.)

•  You must check the operation of the model before every 

flight to insure that all equipment is operating and that 

the model has remained structurally sound. Be sure to 

check clevises or other connectors often and replace 

them if they show any signs of wear or fatigue.

•  If you are not an experienced pilot or have not flown this 

type of model before, we recommend that you get the 

assistance of an experienced pilot in your R/C club for 

your first flights. If you’re not a member of a club, your 

local hobby shop has information about clubs in your 

area whose membership includes experienced pilots.

•  While this kit has been flight tested to exceed normal 

use, if this model will be used for extremely high stress 

flying, such as racing, or if a power system larger than 

one in the recommended range is used, the modeler is 

responsible for taking steps to reinforce the high stress 

points and/or substituting hardware more suitable for the 

increased stress.

Remember: Take your time and follow 

the instructions to end up with a well-

built model that is straight and true.
