Wot Trainer - Instructions

  C o n t r o l   t h r o w s

For initial flights, we recommend the following:

Elevator:  

10mm up

 

 

10mm down

Rudder:   

25mm left

 

 

25mm right

Ailerons:  

8mm up

 

 

8mm down

  B a l a n c i n g   t h e   m o d e l

The Centre of Gravity (C/G or Balance Point) should be 89mm 
(3.5") back from the leading edge of the wing at the root, this 
being  the  centreline  of  the  wing  joining  tube. This  should  be 
measured  with  the  fuel  tank  empty.  Support  the  completed 
model under the wing either side of the fuselage at this point 
and add weight or adjust the position of the radio battery in 
its bay as necessary to achieve a slightly nose down attitude.  
A  model  that  is  not  correctly  balanced  will  not  perform  as 
it  should  and,  at  worst,  be  unstable  or  unflyable,  leading  to 
damage to the model or injury to yourself or others. Do not 
miss out this step in completing your Wot Trainer!

•   Completely charge your transmitter and receiver batteries 

before flying.

•   Carefully check your model over to ensure that all screws 

are tight and everything is well bonded.

•   Double-check the Wot Trainer’s Centre of Gravity.
•   Check the control surfaces for both the correct throw and 

direction. Ensure that each surface moves freely, without any 

binding.

•   Check the receiver aerial is fully extended.

•   Ensure the wing bolts are tight.

We recommend that your completed model is checked over 
and  test  flown  by  a  competent  pilot.  All  subsequent  flights 
should also be supervised, and assisted where necessary, by an 
experienced pilot until you are considered safe to fly the model 
unsupervised. Always fly the Wot Trainer in a safe location at 
a recognised club. For further information on flying in the UK,
