I.  IMPORTANT SAFETY PRECAUTIONS TO PROTECT YOUR MODEL, YOURSELF & OTHERS 

1.

 

This product should not be considered a toy, but rather a sophisticated, working model that functions much like a 
full-scale airplane. Because of its performance capabilities, this product, if not assembled and operated correctly, 
could cause injury to you or spectators and damage to property. Maxford USA provides you with a high-quality, 
thoroughly tested model airplane kit with assembly instructions. However, the quality and capabilities of your 
finished model airplane depend on how you build it, and your safety depends on how you use and fly it. Any 
testing or flying of this model airplane is done entirely at your own risk. 

2.

 

Assemble the model airplane according to these instructions. We recommend that you do not alter or modify the 
model beyond the assembly options covered in these instructions, as doing so may result in an unsafe or 
unworkable model. In a few cases the instructions may differ slightly from the photos; in those instances the 
written instructions should be considered as correct. If you have any question or concern about these instructions, 
before you proceed with assembly of this product, contact us at (562) 529-3988, Monday through Friday, except 
national holidays, between 9 AM to 5 PM Pacific time. 

3.

 

It is your responsibility to install the R/C system and other components in such a way that this model airplane 
passes all applicable safety/range tests and that the power system and controls operate smoothly and correctly. 

4.

 

Recheck the operation of this model airplane before every flight to ensure that all equipment is still operating 
correctly and that the model has remained structurally sound. Also, before every flight check all clevises and 
other connectors; do not fly without replacing any that you find damaged or defective.
