Creating a moving machinegun

the fan does not exist? Exactly it is indicated on the diagram that you have to buy it... this motor must accept 3 volts maximum? on the other hand the consumption exceeds the few milliamps of the diode, hence the problem? so personally look at the voltage of the smoking heating element and if OK plug it into CN 11, if it's too fast? only solution, diodes in series in the power supply good evening

The company did some research bit they only have a single relais that was for 12V required, and a double one with 4.8-6.0V required. The led connection has 4.5V only.

Where i could have connected the MG motor in series with the smoke fan, but ofcourse with the relais between the connection and the MG motor.

Could have been:
Smoke off = Smoke off and MG motor off
Smoke On = Smoke on and MG motor standby
Rear Lights On = MG motor through relais on.

Gotta do some research into this TK7.1 board, i really like the idea of more smoke at higher engine rpm, hope that would work with turret aswell (as Panther turret rotation speed was dependent of engine RPM, the barrel smoke after a shots looks awesome aswell, in that case i could live without the BB’s

It could have been:
Smoke off = Smoke off and MG engine off
Smoke on = Smoke on and MG engine on standby
Tail lights on = MG engine via relay on?
I admit to being a little lost? in fact you are talking to me about a 7.0 type card without a fan, and now a 7.1? OK for the relay there are small ones in 5 volts (which must be the voltage of the fan?) However how do you put it on standby? Are you also talking about the LED rear lights? to control the relay? see if the relay will stick well?

The TK7.0 board doesnt have a engine fan connection that is correct.
The TK7.0 does have a connection for smoke (which is two connections 1x Heater & 1x Smoke fan)

But nevermind all my gibberish, im sticking to the TK7.0 for now, disconnecting both smoke connectors and using the smoke-fan connection for the MG.
