Nine eagles yak 54 chatter problem
Im new to the rc world having just seen and bought a nine eagles yak 54 rtf off ebay, and was wondering if someone can help a new guy out. I have only just recieved the aircraft today (yet to fly it) and i have noticed that when the tx and yak are both powered up that there is alot of chatter on the elevator servo (i can hear and see it moving without any control inputs). I have also noticed that nose up inputs are much slower/incremental than nose down elevator control.
Is this normal? What can I do to fix this or should i just return it?
