NOTE: LIGHTS - 

The LED labeled wire plugs into a selected channel to operate the light 

system.

 

 

NOTE:

 The BVM factory demo model flew 

without Gyro assistance. If you opt to install 
a Gyro, be sure to check for proper control 
surface corrections. Have the Gyro 
activated by a 3 position switch on your 
transmitter. Make the first take-off with the 
Gyro off until a safe altitude is attained. 

First Flight Profile 

Make the first flight with the gyro “OFF”. 
 
Flight Time – There is 9+ minutes of fuel on board. 

The BVM demo model’s transmitter timer was set for 7 min for a “Top Gun” routine. On the 
first flight, land a few minutes early to check fuel consumption. Adjust the flight timer 
accordingly.
