WARNING!
Mechanical alterations on the Tactic TTX410, TTX610, and TTX810 radios require opening the
transmitter case. Failure to follow all instructions below can result in permanent damage to the transmitter and
void the warranty. Contact Hobby Services if you do not feel comfortable that you can safely and accurately
perform these steps.
Case Separation and Disassembly
1. Make sure to fi rst remove all batteries from the battery compartment!
Failure to do so could result in permanent damage to the radio
and void the warranty.
2. Remove the six screws from the back of the Tx case. Put the screws in a safe
place for later use.
3. Carefully separate the case rear away from the case front and note exactly how
all wires are routed inside the case. Taking a picture of the wires in place may
be helpful for re-assembling the case later. Do not disconnect wires from the
pc board.
4. Carefully lay the radio face-down on a soft, non-abrasive surface, with the case
rear opened to expose the inside of the radio.
Throttle Ratchet Bar
1. A long metal bar will be installed vertically across the rear of one gimbal.
This bar provides resistance and a ratchet feel for the throttle control. Note
the small detent in the middle of the bar, and the tip of this detent points
towards the gimbal. Two mounting screws hold the bar into place. One
screw will be inserted fully into the taller mounting post. The other screw
will be partially inserted into the shorter mounting post, to function as a
tension adjustment for the throttle stick. Note the depth at which this screw
is inserted prior to removal. Remove both screws and the ratchet bar from
this gimbal.
2. Position the throttle ratchet bar onto the mounting posts for the opposite
gimbal, making sure the detent in the bar points at the gimbal. Install one
screw fully (don’t over-tighten) into the taller mounting post. Install the
second screw partially in the shorter mounting post, to a depth similar to
when it was removed to provide adequate tension for this stick.
Elevator Arm and Spring Removal
The gimbal now with the metal throttle ratchet bar will still have a plastic arm
and spring for the vertical movement of the stick. The arm and spring must
be removed from this gimbal and moved to the other gimbal.
1. With a pair of hemostats or needle-nose pliers, carefully grasp the loop end
of the spring and slide it off the end of the arm.
2. Lower the spring to slide the opposite loop end off the lever located downward
inside the gimbal assembly. Set the spring aside.
