    I'm assuming you've tried swapping channels to see if it's an issue with the esc?

    Oh, man! This ****ing receiver is kicking my ass! Everything works except ch-3 -- the motor! I try another receiver and things work, but the installed receiver -- a Novak Xxtra -- it just won't work the motor. ****ing thing!!!!!

    I'm about ready to tear out this receiver and put one of my test-and-set-up receivers in there -- gotta finish this and get it in the water so I can address Kim's RTR and get back to production work for Bob. I'm way behind.

    fit to be tied!

    Excellent suggestion, Andy. If this arrangement glitches I'll move things around. Thanks for the heads up. How are things over there in the Empire these days?

    Hey, Tom! Whaz up?

    I have on hand a sizable collection of various type 75mHz receivers -- I use the biggest receiver that will fit the particular job. I save the mini-receivers for the the r/c submarines that employ the 1.25" SD.

    You have to consider the geometry of the receiver for overall fit. And a big consideration is how the receiver ports are oriented -- do they go along the length of the receiver, or do the ports come off the top? In tight confines such things must be considered.

    My next installment will demonstrate how I crimp on new servo lead pins after I optimize the length of a devices three-wire lead.

    Is there positive connection between the servo push rods and the "pedals" on the dive planes and rudder control arms, or do they just abut against each other?

    If its the latter, is there a spring that maintains tension on the pedal arms to move them back when the push rods retract back?
    The SD's pushrod pushes against the top end of its bell-crank. The two bell-cranks share a common spring that pushes them at the bottom.

    So those 2 small joysticks control the diveplanes and rudder, one for each. In theory, a pair of 1/16 Navy SEAL action figures can drive this thing. One to handle the dive planes, the other to steer. OR one 1/12 or 1/6 action figure operating a one man SDV.

    Would be nice to have a scale cockpit with SEAL figures one can drop in in lieu of the WTC when displaying the sub.

    Anyway, What's the reason for forward location of the servos?
    First I get this thing to work, later I finesse things to permit an open cockpit.

    The tight confines between stern and after end of the SD precludes the traditional linkages and running gear coupling.
