Heng long tank but with my own radio?

I agree the HL traverse motors are pretty decent and there are a bunch of different ones to tune how you want the rotation to act.

Not to be argumentative, but I will disagree with pretty much all of rest. The 7.1 does have 6 servo ports. All of them work.

CH5 is the port controlled by the 7.1 transmitter slider (trim slider on a standard transmitter) under the right stick. Technically since it can control a 360 servo, that could be used for a rotation servo, but I will say it wouldn't be a very good way to control the rotation of the turret.

CH3 and CH4 are for external ESC connections of which people have tested that function and it does work. I have plenty of 7.1 MFUs running on 7.0 transmitters and the servo recoil and servo elevation works fine with the 7.0 transmitter.

The only thing the 7.1 transmitter gets you is control of CH5 which folks are typically using for a CROWS/remote gun rotation or a CITV rotation. In some cases I've seen it wired up for a mine plow, a crane, a spade on artillery, rotating commander's cupola, or a troop door for an IFV.

There is a special "rotating" warning light that uses CH6. Rotating is in quotes because technically it doesn't rotate, it just flashes the LEDs in a sequence mimicking a rotation action.

With all respect. I think you misread or misinterpreted what I wrote. The question I was answering was about "servo" compatibility. In such I am correct that only three of the ports are active for this function. Servos do not work properly in the other three ports. Also I clearly stated that to use the "third" servo option the OP would need a 7.1 TX (his prior question was about running three servos at the same time) this is also correct. Nowhere did I say one can not run servo recoil or servo elevation on a 7.1 MFU with a 7.0 TX. I don't know where you pulled that from in my response to the OP hence maybe you misread or misunderstood what I wrote.
