The VNR 3DXL™ is not a toy. It is a precision machine requiring proper assembly 
and setup to avoid accidents and it is the responsibility of the owner to operate this 
product in a safe manner as it can cause serious personal injury and damage to 
property due to carelessness or misuse.

When charging the battery pack, do not overcharge! If batteries get hot during 
charging, discontinue charging immediately and disconnect the battery from the 
charger. Never leave battery unattended while charging. If you are unsure of how to 
charge this battery, please contact Venom Air Corps™ or seek the advice of your 
local hobby shop. Never let children charge batteries without adult supervision.

To avoid an out of control helicopter always turn the radio on first then connect the 

battery to the helicopter. When turning off the helicopter, always disconnect the 

battery first, then turn off the radio. If the orders are reversed the helicopter may 

become uncontrollable and cause serious damage.

If you are in doubt of your ability, we strongly recommend that you seek assistance 
from experienced radio controlled helicopter pilots or join your local helicopter 

flying club to gain the required knowledge and skill. As the manufacturer and 

distributor, we assume no liability for the use of this product.

Children under the age of fourteen (14) are strictly prohibited from playing with this 
electric helicopter.

WARNING!

READ BEFORE FLIGHT

I. INTRODUCTION

Venom Air Corps™ Night Ranger 3DXL™ is a high performance Ready-to-Fly Collective Pitch (CP) 

Aerobatic Electric Helicopter for indoor flying and outdoors on calm days. At about 610 grams, the 
VNR 3DXL™ will fly for 5-8 minutes on the 11.1v 10c 3s 1500mah LiPO battery, depending on the 
type of flight. Although the VNR 3DXL™ is not difficult to operate, it does take more skill and practice 
to master than a fixed pitch helicopter. We recommend that you read these instructions thoroughly and 
carefully first. If you have any questions, please feel free to call our customer service department or 
contact your local hobby shop or local flying club. All are excellent resources for information and 

are more than willing to help new hobbyists.
