I have a 24" HD extension to each tail servo and 12" to each ail. servo. The antenae goes out the wing.

I brought back the 2 bad tail servos to my LHS. He first wouldn't replace them because there was a little bit of oil residue from when I ran my engine. But I said they have a 3yr warranty. They are less than a month old and never been flown. I really don't want to put a plane up in the air when the servos twitch like crazy. Finally he swapped me for new ones.

I haven't checked the new ones yet. but will soon.
