There is not an a simple way to boost the voltage of the aux output, no.
The aux output can do a max of 5 volts, but it also does less than that if you are varying the speed of your fan, so it is not a fixed voltage. The way it modifies the voltage is through high speed switching, which I suspect your voltage booster does not like. Secondly, even if your booster worked, that extra voltage has to come from somewhere - and it comes through an increase in current. You could find yourself exceeding the limits of the Aux mosfet, or of the TCB regulator.
It's not impossible to boost the voltage, but you'd need a 7.4 volt source, and then feed the Aux output into another mosfet circuit, which would use the Aux as a signal only, to control the higher voltage. But that requires you to make another circuit.
If you don't need variable speed control, just on/off, then you could use one of the General Purpose I/O ports to control a relay, which would then switch your 7.4 volt source.

Glad you worked it out.

I'm not sure I would be inclined to update the guide for these receivers specifically, the guide hasn't been updated in years and if I add one new radio system then it opens the door to adding all new systems, of which there are now countless.
But certainly if you find that some receiver which should work, does not, then let us know that here so we can troubleshoot.

Yes, your description sounds correct to me.

Hi Bill, yes, you could set up this kind of steering arrangement with the TCB, in a kind of round-about way. You'd just have to select "Car" as the Vehicle Type on the Motors tab of OP Config, and then use the drive motor ESC for one track, and the "Steering" motor ESC for the other track. Yes, OP Config is going to call it "Steering" but it doesn't matter what you attach it to, the important thing is that under the "Car" type there is no mixing between the two (as there would be with Tank or Halftrack vehicle types), so that lets you control each track manually with the sticks.
However, if that's all you wanted to do, you don't need the TCB at all, just connect your two speed controls directly to your receiver.
Also, it's important to keep in mind that if all you have is a PWM receiver, that won't work with the TCB - it only works with receivers that can output PPM, iBus, or SBus.

Just sounds.

Hi Tom, in fact yes you do still need to remove the positive terminal from the servo cables if you are using the RC version of the Sabertooth. The RC connections on the RC Sabertooth provide +5 volt power, they are thinking you would normally connect those to an RC receiver and that way the Sabertooth could provide power to your receiver. But since you are connecting to the TCB, and the TCB already has its own 5 volt supply, the two would be fighting each other if you connected them, and you risk burning something up.
So you can still use it, but just remove the positive wire from the connections (leaving only ground and signal).

Hi Tom, I've not used the DasMikro devices before, so I can't speak from experience. But I do know that the Mini firmware needs to match the version of Flash you're using. So if you're using Flash V4 then the firmware on your DasMikro Mini needs to be whatever version Thomas has that will work with Flash v4. Maybe DasMikro ship them with old firmware. When (if) you can connect to the device with Flash, the Mini's firmware version will be shown on the Diagnostic tab. Under the Modul drop-down menu at top there is also an option to update the Mini firmware, but I don't know if this works anymore, since I assume Flash goes out to the internet to Benedini's website to get the firmware. If it is a firmware issue, and you can't update the firmware on the Mini, then I'd try looking for a place to download somewhere the older V3 version of Flash, and maybe that will work. I really think DasMikro shouldn't be selling hardware that they can't also provide the firmware and software for, because without those the board itself is not of much use. Finally, there are not many people here reading these posts. There is a very long thread on the DasMikro boards over on RCTankWarfare, I'd recommend trying to ask your questions over there where more people might see it: Dasmikro (TBS Benedini clone)

I have built my own smoker unit, and it works very well. The only issue I’ve noticed is that when you regulate the percentage through the OP Config, it still seems to use close to 100% power on motor startup. During the first second of startup, the heating wire sometimes gets extremely red hot. Hi Hades, you are correct, there are a couple seconds at engine start where the heating element was set to 100%, regardless of what the user specifies for a max heat percentage in OP Config. This was an oversight on my part. I have posted a new TCB firmware release (0.94.05) that should fix it.

Hi Rock, I doubt the extra ~volt or so will hurt the heating element, it's just a wire that gets hot. But since you are using Separate Heat & Fan, if you want you can effectively just drop the voltage to the heating element in OP Config by setting the Heat percentage (for all three: Idle, Fast Idle and Max) to something less than 100%. About 80% should give you the equivalent of around 6 volts.

Tom, it seems like these are questions that you will be able to answer yourself better than anyone else, once you have the model in hand.

Hi Tom, the ability to set the endpoints is there so you can make sure the servo does not try to move beyond its physical limits, which might damage the servo or the recoil/elevation mechanism. So yes, I would think it's important to adjust the endpoints to your particular setup.

As I said above, it is not worth it.

The delay option that is present in OP Config does not delay the barrel recoil - the barrel recoil occurs immediately, if you have a delay set, then that is the delay between the time when the barrel recoil occurs (immediately), and when the light/sound/track recoil will occur.
So that will do what you are proposing, except it sounds like you want the light/sound to occur immediately, and then the track recoil to occur after the delay. If that is the ask, then I'm afraid I don't think the effort is worth the trouble.

Tom, the setting for what I understand you to be proposing is the same as the one I have already mentioned: Delay between recoil and light/sound.
If you want this to be 400mS, just set it to 400.
