• Get help from an experienced pilot when learning to 

operate engines.

•  Use safety glasses when starting or running engines.

•  Do not run the engine in an area of loose gravel or sand, as 

the propeller may throw such material in your face or eyes.

•  Keep your face and body as well as all spectators away from 

the plane of rotation of the propeller as you start and run 
the engine.

• Keep items such as these away from the prop: loose 

clothing, shirt sleeves, ties, scarfs, long hair or loose 
objects (pencils, screw drivers) that may fall out of shirt or 
jacket pockets into the prop.

• Use a “chicken stick” device or electric starter; follow 

instructions supplied with the starter or stick. Make certain 
the glow plug clip or connector is secure so that it will not 
pop off or otherwise get into the running propeller.

• Make all engine adjustments from behind the rotating 

propeller.

• The engine gets hot! Do not touch it during or after 

operation. Make sure fuel lines are in good condition so 
fuel will not leak onto a hot engine causing a fire.

•  To stop the engine, cut off the fuel supply by closing off the 

fuel line or follow the engine manufacturer’s 
recommendations. Do not use hands, fingers or any body 
part to try to stop the engine. Do not throw anything into 
the prop of a running engine.

FLYING

 

The Tower Uproar is a great-flying sport airplane that 

flies smoothly and predictably, yet is highly maneuverable. It 
does not, however, have the self-recovery characteristics of a 
primary R/C trainer; therefore, 

you must either have mastered 

the basics of R/C flying or obtained the assistance of a competent 
R/C pilot to help you with your first flights.

Takeoff:

 If you have dual rates on your transmitter, set the 

switches to “high rate” for takeoff, especially when taking off 
in a crosswind. Although this model has excellent low speed 
characteristics, you should always build up as much speed as 
your runway will permit before lifting off, as this will give you 
a safety margin in case of a “flame-out.” When you first 
advance the throttle and the tail begins to lift, the plane will 
start to turn left (a characteristic of all “taildraggers”). Be 
ready for this, and correct by applying sufficient right rudder 
to hold it straight down the runway. The left-turning tendency 
will diminish as soon as the tail is up and the plane picks up 
speed. Be 

sure

 to allow the tail to come up. Don’t hold the tail 

on the ground with too much up elevator, as the plane will 
become airborne prematurely and possibly stall. When the 
plane has sufficient flying speed, lift off by smoothly applying 
up elevator (don’t “jerk” it off to a steep climb!), and climb 
out gradually.

Flight:

 We recommend that you take it easy with your Uproar 

for the first several flights, gradually “getting acquainted” 
with this responsive sport plane as your engine gets fully 
broken-in. Add and practice one maneuver at a time, learning
