Hitec has sold 10's of thousands of digital servos and our return rate is no greater than that of the other manufactures. The 5945's are as good as it gets and the 5735 is quickly becoming the servo of choice for rudders.
What you don't read here are the thousands of people that are using those servo with incredible success, although there are many positive posts here too, people are more likely to post problems here than they are if they have none. While there are a few people that have had problems that is not uncommon with any brand of servo. You have to expect that when a few people make waves there will be a ripple affect. That is not to say that Hitec is insensitive to these problems. We will do everything in our power to take care of the customer and continue to improve upon our products to provide the quality affordable products we are known for.
As for your anxiety over flying your $4000 airplane.... to help relieve some of it, you might want to give the equipment some time on the ground first just to be on the safe side. I wouldn't expect to get rid of it all, after all.... it is a $4000 airplane!
