Setup

DO NOT ATTEMPT FLIGHT IF THE WINGS ARE WARPED.  

Inspect the wings for any warps that may 

have occurred when covering the model, or while the model was in storage.  Remove all warps before 

flight.  

Lack of aileron control on this model will make flying with a warped wing difficult.

Rudder - 

Center the rudder.  Then, set the direction, rate of travel, and dampening (expo) of the control.  

The rudder servo should be controlled by the aileron channel on your radio, as the rudder on this model 

also controls the roll of the aircraft.  The rudder should follow aileron stick travel, i.e., moving the aileron 

stick to the 

right

 should move the rudder to the 

right

.

Elevator -

 Center the elevator.  Then, set the direction, rate of travel, and dampening (expo) of the 

control. The elevator will be controlled by the elevator channel on your radio.  Moving the elevator stick 

back

 

should move the elevator 

up

.  Moving the elevator stick 

forward

 should move the elevator 

down

.

The 

Ricci Triplane UM

 

was designed to be a very docile flyer.  We set up our flight controls with fairly 

minimal throws.  With the push rods connected, per the instructions in this manual, set the control throws 

as follows:

Preflight

It is recommended that you have an experienced pilot assist you with preflighting your new model.  

Just like having someone proofread something you’ve written, having a second 

fresh

 set of eyes inspect 

your final product is often helpful in avoiding disaster.

While not a thorough preflight check, listed below are some of the major items that you should consider 

checking when developing your own preflight check list.  Get in the habit of always preflighting your 

models 

before

 

every flight

.

Weight and Balance

 

-

 Check the balance of your model (C.G., center of gravity).  For proper 

performance, the model should balance using the marks etched in the 

bottom

 of the 

right

 and 

left

 upper 

wing panels (or no further aft than 3/4 inch from the leading edge of the 

upper

 wing).  Use your 

right

 and 

left

 index fingers to suspend the model from 

below

, at the marked balance points.  If the horizontal 

stabilizer appears to hang level, the model is properly balanced and ready to fly.  

If the nose or tail of the model hang 

down

, move the battery forward and backward to make subtle 

changes, or add clay ballast to the nose or tail as required to obtain proper balance.

Check Weather

 -

 

The

 

first flight should be outdoors in 

zero

 wind conditions.  The 

Ricci Triplane UM 

can 

fly in winds up to 5 miles per hour.

Inspect the Airframe 

-

 

Always check for warps and obvious signs of wear or damage.  

Do not fly a 

warped or damaged model.

Inspect Control Surfaces 

- Always check control surfaces for center, proper direction of travel, rate of 

throw, secure push rod connections, hinges, and receiver/servo mounting hardware.

Check Wing Attachment Points 

-

 

Always make sure you inspect for damage and wear.  Make sure that 

the wing and wing struts, if applicable, are properly attached.
