I will follow along with interest, here and at RC Universe both. The early Panzers (I-II-III) are my favorites. Your weathering is looking very good.
I am curious about the "APO ESC" and the larger red board highlighted in this picture. Do you have links? I am always trying to learn about new products I haven't heard about before.
ha, the red board is an 2*60w AMP, tested by Thomas from Benedini, I guess my tank will be very loud and produces good quality sounds. I will hook up 2* B&W speakers from my former car to it. the APO esc is from a Chinese Robotistic company, delivers 120w each, which is more than capable to handle the elevation & turret rotation motors. The big day is near, I will do the full test, with all the motors.

It is about time to share my build.
The project starts from Oct.2018, and I am performing weathering at the moment.
All the electronics are ready.
fuse box, TCB, Benedini TBSv2, Sabertooth 2*32, 2*APO esc, Henglong smoker unit
The systems will use 2*12v acid battery, the drive motors are 2*250 bushed motor.
However, I need to design an internal housing for all the electronics.

This information is in the Wiki, but the answer is, Prop1-3 (and actually all 8 RC outputs), as well as the two RADIO connections, provide regulated 5 volts. The TCB can source up to 3 amps for all 5 volt outputs combined.
jeez,,,how can I miss the last part of the paragraph......... Lukez, appreciate it. Larry

Hi, guys,
After radio’s set, now move to next stage.
I learnt from WIKI the TCB best working voltage is from 7-15V, which voltage is also shared by some TCB ‘s output ports.
The question is what’s the voltage of prop1-3, and radio. Are they constant independent 5v, like most BECs? Or do they also share the same input voltage like other ports?because the Benedini’s working voltage is around 7v.
I could try but I don’t want to risk burning the boards, as it too long for them to arrive.
Thanks in advance
Larry

finally, I found it is working with r2008sb.
r2008sb has only sbus, not like the r3008sb which also supports sbus2.
However, only 2 out of 8 position switches, 1 rotary knob can be recognized by OP config. I will try the Delta8 receiver some days later.
It will work with R3008SB if you configure it correctly. 3008 still uses original SBus out the "8/SB" port, and even so-called "SBus2" is not a different protocol, it is the very same thing only it accepts 2-way traffic. Did you try both CH mode B and D? You have not told us.
Every manufacturer is different in how many channels they pass through over the SBus connection. The 10J is FHSS and is considered to be in Futaba's budget line of transmitters (although it is still ridiculously expensive). Possibly it only passes 8 channels over SBus, or even less. Even without SBus, the 10J has rather more physical controls (13) than it does actual channels (10), so inevitably many of the switches are not going to be used or else you need to configure which ones are transmitted.
It is not clear to me the Delta 8 is going to give you anything different, if the limitation is with your transmitter.
I just looked up at Futaba’s web and found out the R2008sb only supports 8 CH although it has Sbus. It makes sense why only 3 switches works now. Now I need to save for a 16SZ or 18SZ.hahaha I will try another 3008 later ,just in case the one I tried is a fake one.

According to page 29 of the 10J manual, you need to set the R3008SB receiver to CH Mode B or D. It's not clear what the difference is between those two modes with regards to the SBus output, possibly nothing. I would try both modes, and connect your receiver to the TCB using the receiver's "8/SB" output.
If you are able to connect to the TCB with OP Config then VMWare is probably not your issue, otherwise you would have had a problem already before that.
Hi LukeZ The difference between mode B(2) and D(4) is the changes in the availability of PWM outputs .

To answer your earlier question, no, the receiver doesn't need an extra power source, it obtains 5 volts from the 3-pin connection to the TCB.
Ulrich confirms the R3008SB receiver works, so yours should too. There are two receiver connections on the TCB, try the other one. In other words, you have probably been using the bottom connector which is labelled for SBus, but try the top one too and see if that makes a difference.
Does your receiver turn on correctly? Is there a light or anything on the receiver that you can use to confirm?
I have not used this receiver personally but just looking at images of it, I see there are two SBus connections on it, one labelled "8/SB" and the other "S.BUS2"
I don't know what the difference is but try both of those, and make sure you have the polarity correct. Possibly there may be some settings in your transmitter to enable SBus, I don't know.
I will test again later night on a native PC as it just occurred to me I am running the setup in the VMware on a Mac. Although the Op config can connect to the TCB in the VM, but still there might be the possibility. Fingers are crossed.

Hello Larry
i have already built in what you are asking for.
radio: Futaba T10J
receiver: R3008SB and also a Cooltech RSF08SB
connected via SBUS to the TCB.
soon i'll test it with some other Futaba RC's and cooltech or corona receivers
no problems. works great great. configuration like shown in the wiki
regards Ulrich
Hi Ulrich Glad your setup works. May I ask the configuration of your setup. 1. Is there a switch or setting in T10J which can force the radio using Sbus. Or is it done automatically? 2. Which mode of 3008 you set to? Is it mode 2? 3. Did you purchase the Tcb most recently? Mine is HobbyKing’s 2019 Jan stock. Many thanks. Larry

It’s spring festival holiday here, all shops are closed. I might want to get a FrSky delta8 later and have another try.

Right, Dipswitch #5 needs to be in the ON position, glad you found that.
Now do you have any issues detecting the receiver?
the TCB still can't read the radio . $_$

I tried a second TCB. Windows XP installed the driver again, and assigned COM5 to the 2nd TCB. But, the OP config won't connect to the 2nd board.
will it be a quality problem?
well, turns out the 5#DIP switch are set to OFF.

Guys,
finally, the TCB is with me. However, I got the 1st problem. Radio can't be detected.
I hooked up PC with TCB, and connected with r3008sb via the 8/Sbus port. Linked with T10j, but, OP config says, radio can't be detected. I am sure the receiver is in the correct mode.
Do I have to connect extra power to the receiver at the meantime it is hooked up with TCB?
