[TowerTalk] Rotor damage prevention

[John E.Cleeve]

Its dark now, raining hard, the wind is gusting, and ones mind, and 
eyes, turn to the mass of metal, moving at the top of the tower. 
Having had one rotor ruined by gusting wind conditions, with stripped 
spur gears. I decided to replace it with an Italian worm gear unit. I 
also decided to try and reduce the mechanical "shock" load placed on 
the "parked" rotor, during high, and gusting wind conditions, by 
fitting a rubber doughnut drive coupler, originaly intended as part of 
a Triumph prop shaft drive train, and bought as a new spare part, 
between the Italian rotor drive plate and the drive shaft to the Yagi. 
The rubber coupler assembly is enclosed and protected from the 
weather, and possible deterioration due to UV exposure. The yagi is 
moving gently in the gusts, with a six inch diameter, rubber doughnut 
absorbing the mechanical stress, I hope......just thought this might 
be of interest to the group...... regards..John. G3JVC
