In order that we can provide a better service to future customers and perhaps to you in the future it would 
be helpful if you could tell us a much about your installation as possible. Please keep a copy fro your own 
records. This could help you set up your installation if the propeller is ever damaged.

Pitch should be given as degrees measured on the back of the blade at ¾ diameter. (That is ¾ the 
distance from the centre of the propeller to the tip or ¼ from the tip in. For a 160cm propeller measure 
20cm in from the tip! You can use an angle finder placed on the blade when it is in a horizontal position 
with the A/C level. 
 
Please post or fax the form to LTS – 64 Wellands Rd, Lyndhurst, SO43 7AD
