Flying

We recommend flying your E-flite

®

 UMX Gee Bee outside in 

calm to moderate winds or in a large gymnasium. Always 
avoid flying near houses, trees, wires and buildings. You 
should also be careful to avoid flying in areas where there 
are many people, such as busy parks, schoolyards or 
soccer fields. Consult local laws and ordinances before 
choosing a location to fly your aircraft.

Takeoff 

Place the UMX Gee Bee in position for takeoff (facing into 
the wind if flying outdoors). Gradually increase the throttle 
to full power, holding a small amount of up elevator and 
steering with the rudder. Climb gently to check trim. Once 
the trim is adjusted, begin exploring the flight envelope of 
the UMX Gee Bee.

Landing

Land into the wind. This is very important for this model. 
Fly the aircraft to approximately 6 inches (15cm) or less 
above the runway, using a small amount of throttle for 
the entire descent. Keep the throttle on until the aircraft is 
ready to flare. During flare, keep the wings level and the 
airplane pointed into the wind. Gently lower the throttle 
while pulling back on the elevator to bring the aircraft 
down on all three wheels.

Failure to lower the throttle 
stick and trim to the lowest 
possible positions during a 
crash could result in damage 
to the ESC in the receiver 
unit, which may require 
replacement.

Over Current Protection 

(OCP)

T

he UMX Gee Bee is equipped 

with Over Current Protection. 
OCP protects the ESC from 
overheating and stops the 
motor when the transmitter throttle is set too high and 
the propeller cannot turn. OCP will only activate when the 
throttle is positioned just above ½ throttle. After the ESC 
stops the motor, fully lower the throttle to re-arm the ESC. 

Repairs

Crash damage is not covered under warranty. 

Repair this model using foam-compatible CA glue or 
clear tape. Only use foam-compatible CA glue as other 
types of glue can damage the foam. When parts are not 
repairable, see the Replacement Parts List for ordering by 
item number.

For a listing of all replacement and optional parts, refer to 
the list at the back of this manual.

NOTICE:

 Use of foam-compatible CA accelerant on 

your model can damage paint. DO NOT handle the 
model until accelerant fully dries.

Flying Tips and Repairs

Always 

decrease throttle at

propeller strike.
