I've got all the guts into my Typhoon project and everything is working (for now) except for the most important thing... that' being the Engel TMAX dive system.
I've double checked all of the wiring twice, and I'm relatively certain that it is connected correctly according to the instructions. I'm using an F-14 Navy Twin Stick for control along with the 12+2 transmitter/decoder module. The dive system is currently set up on channel 5 direct from the main receiver, NOT the decoder. Fine trim is connected to channel 6, again on the main receiver. Trim control is currently connected to K7 on the decoder, which is a proportional channel, but not direct from the receiver.
What is happening right now is that the system will operate properly for the main flood/dive operation. It does not respond in any way to inputs from Ch.6 or Ch.7. I tried swapping those channels out, but it makes no difference. I get no fine control or trim control. The units do not react in the slightest to these inputs. To further confound me, from time to time when I test, a command for neutral buoyancy will flood the tanks, but then immediately thereafter my stern tank empties and returns to fully retracted with the bow tank fully extended.
I've double checked and the F-14 is operating on PPM and the setting for the decoder is PPM as well.
I know the instructions say that the ballast needs to run off of true proportional channels from the receiver, and I do have both the main flood/blow function and the fine trim function off of true proportional channels (the two center sliders on the transmitter). Would having the trim function even plugged into the decoder cause this? I haven't had the chance to try disconnecting that yet...
Also, on a quasi-related note, I currently have my bow retracts working off of a momentary-retract and latching-extend switch on the 12+2 module. This is done so that the bow plane servo can remain actuated while the planes are extended. In a momentary setup, the relay does not stay actuated and the bow servo does not function. My issue is this: When the extend command is given, the switch latches, even when you return it to center position. If I forget to unlatch the switch, BOTH the extend and retract relays activate and all sorts of badness happens. Is there a switch that I can use that latches, but only when the switch is in the activation position? As it works now, the switch latches when you flip it down, but then to turn it off you need to return the switch to center position and then back to flipped position and then back again to neutral position (who THOUGHT of that?!?) Can I modify the existing switch to eliminate the latching ability so that the relay is actuated only when the switch is in that position?
Any help that you can offer would be greatly appreciated!
