FlyingFoam Nurf 

General Assembly Instructions 

These instructions apply to the Nurf, an all EPP forward swept flying wing available from 
FlyingFoam.com. 

Building and operating a remote controlled aircraft involves risk.  By building and flying 
this kit you are accepting said risks. We assume a basic level of model aviation 
knowledge in both building and operating our aircraft.  Please seek experienced help 
when required.  We make every effort to ensure our kits are of the highest quality, and 
any documentation is as accurate as we can make it at the time of writing.  Due to the 
flexible nature of our designs there are many ways to successfully build our kits.  We 
document what we feel is the best method for general-purpose use.  Please refer to 
www.flyingfoam.com for further details. 

Requirements: 

 

Radio/receiver with elevon mixing 

 

2 mini servos (We like the Hitec 82MG)

as a 9000mAhr 3S) 

 

Electronic Speed Control: Match to your motor (40+ amps would not hurt) 

 

Prop: 9" for ground clearance (12" max to clear vertical stabilizer, but you might 
want a folder or add landing gear for ground clearance) 

 

Options:  Folding prop and spinner

 

Included: 

 

1.3# EPP fuselage core (cut in half for easy access)
