These servo arms do the job and are a good value. In my opinion, they are made to be sacrificed, along with a clevis to take the energy from a hard impact, saving the more costly components on the aircraft such as the servos. Check the condition of these and other components of your pre-flight check. These are inexpensive and key to the operation of the Apprentice S. Keep spares of these and the also order some extra clevises for your tool box-- just in case. I hope the info helps :-)

I bought the servo arms for the Apprentice 15e aileron servos. Perfect fit, but as with the original part, they are not very durable and break easily. Could be made a little thicker or of a more durable material.

In my opinion the original servo arm should not have broke. The one that broke was for the elevator but the rudder servo arm did not break. That is why my best best review can be average because I expect better than average from Horizon.

I really like the Apprentice S 15e , but the aileron servo horns not so much... I have about 6 flights on my Apprentice and today while doing my preflight inspection noticed that one of the aileron servo horns stripped on the inside where it attaches to the servo is stripped!
