A proven device to secure the rudder. Material is ASA plastic that is weather resistant and sun resistant. Recommend to use a good stiff rope such as 1/4 inch Dyneema Flight Line rope or similar to secure the rudder gust lock. You will need 30ft of rope total and you will have some left over.  The rudder gust lock will not scratch paint.   Five internal print processes to tailor the print to be essentially solid in the middle and more flexible at the edges.  
 
Note: This is for the rudder gust lock only.  The elevator gusts locks and rope are sold separatly.
