Exotek F104 bolt-in type servo mounts
Exotek have produced these F104 bolt-in type servo mounts. Six months of track testing have proven that these mounts are the real deal for your F104 or EXO104. Quick position changes or servo removal are achieved via 4 cupped set screws that grab the servo on both sides like a vise without tweaking the chassis or damaging the servo. It works with standard servos or lay down servos, with the latter having the option of quick Ackerman changes.
