as i have said a few times in RCU i have just bought a nexstar what i want to know is what the AFS should be set at i know everybody says they disconnect it but i plan on giving it a try, tower hobbies say that it should be set to about 35% for a beginner but when i test it at 35% gain using a flashlight nothing happens. when i set it to about 75-80% it works. i hope someone can help me
