They were factory installed, they were not however connected to the control surface. When I connected them to the control surface, it pulled to one side drastically. It had nylon clevises installed. Once adjusted to allow me to center the control surface, there was less than 1/8" of threads remaining in the clevis. After the first trim flight I needed to adjust further, but couldn't screw out the clevis anymore without risking it popping off under strain (such as in flight). All of this was done with the "factory installed" hardware. It wasn't until I upgraded that hardware that I switched connection techniques (Z bends). This was actually the result of a another newbie mistake. When I bought the larger pushrods, I remembered to get the clevises but failed to purchase any sort of servo side connector.

I don't mean to sound confrontational but I think Bruce's statement that if they were factory installed they couldn't be too short is misleading, and implying bad advice. I may not have years of experience in this hobby, but I am a quick learner. Just because this was an RTF, doesn't mean it was perfect or ready to fly for that matter. Just because they were factory installed didn't stop me from checking that the servo travel was the correct direction, it didn't stop me from tugging on all of my control surfaces to ensure the hinges were properly installed, it didn't stop me from ensuring the covering was sealed properly. As it turns out even after doing all of this it didn't stop my instructors from finding out on my first pre-flight check that my throttle was binding, my front wheel was not straight, and the CG was slightly off (yes I should have caught this sooner). This isn't even accounting for the push rod issue, which as Bruce pointed out might have been easily resolved by changing the servo orientation.

Maybe I was wrong to bring this up here, but I thought I was doing a service to the original poster by sharing experiences I had with the same plane. I wasn't saying he would have the same issues, but they are things to keep an eye out for. At the very least these things deserve a double check.
