CONSTRUCTION MANUAL

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.
