on your first photo, MFU, is it a Clark TK card? Personally, I would temporarily remove the servo control rods and connect them directly to the receiver (in the absence of servo control) in order to see what is happening ... and to know which stick of the transmitter controls what? seems silly, but not ditto on all TX, and will confirm if everything is OK, one last thing, are you sure that your battery is properly charged? do the motors run normally or not?Herr Dr. Professor wrote:I just returned the wiring through the MFU as it was from the outset. I am now seeing that everything works, but for two new problems.
1) the recoil servo operates momentarily as it should; however, the barrel seems not to be connected to it. I will investigate this to see if a mechanical link has come loose.
2) the elevation servo is operating erratically:
...a) Sometimes it operates momentarily as I switch on the MFU power. I believe this is normal.
...b) Sometimes it operates in response to the transmitter control, but will not stop turning until and unless I switch off the MFU power.
...c) Sometimes it begins operating immediately as I switch on the MFU power, and it will not stop until and unless I switch off the MFU power.
(Phenomenon b initially led to panic as the arm of the servo wrapped up wires resolutely. I quickly realized it would be good to remove the servo arm not only from the gun, as I had already done, but also to remove the servo arm from the servo, too. )
important, check the servos setting in the transmitter menu? neutral position (O) and travel (100% minimum) all this has to be done directly on the RX without going through the TK plate
