Someone should put a 1/16 Tiger or KT in the middle, and few of these minions painted yellow all around the bigger tank. It would make for a great photo :)
Yes I would do that but I do not have a 1/16 tank. Don't want either as no room to store it. I have +300 models so wife thinks i am insane now lol :crazy:

Recently rewired the tank so that the motors are in parallel drive as opposed to series wiring. added a gun barrel to the Tan Panther as well. And a power on LED. The Led is on when the switch is on and the tank is not moving.

The Tan Panther micro Tank can run in a very small area so a kitchen table is ideal. A small scale obstacle course can be set up on the table for a challenging run while sipping some morning coffee :)

Tank on the left is being tuned for proper speed. The one on the right has been tuned with a 10 ohm resistor.  Both of these Tanks come with on\off switch and charge plug.

No this one is not going to grow up and in fact it has its legitimate place as the world's smallest "Radio Remote Controlled" 2 channel tank.

These very small tanks have a place in my collection because they can be operated in a very small space. I can run round and round the bathroom sink with this little bug. Not something a larger model can do. I have many remote controlled models of many scale size and enjoy them all as I am a radio control enthusiast and have been for 40+ years ;)

I just got some very small ESC's that may allow for these tanks to be upgraded to Hobby grade electronics 8)

This will require my smallest HG radio setup to date.

The scale has finally been figured out 1:77 !

Post by modler »

Ok boys, I am going for it, "World's smallest Hobby Grade RRC Tank @ 1:77" with DSMX 5 channel RX with Telemetry, dual motor track control.

I have a little time to make this happen. Thanks to the new Ultra micro ESC with Track mixer and a RX42 Ultra micro RX

Now comes the fun part, wiring it all together.

The Panther here is 1:77 scale. One thing that I do know is that this is the smallest RADIO CONTROL Tank available at this time even in its stock form with the Toy Grade radio control system

It will now get a upgrade to 5 channel DSMX Telemetry Receiver with the smallest dual channel ESC with mixer that is available at this time.

This new Ultra micro dual ESC (bottom) is going to make this possible. It is almost half the size of the Das Mikro SINGLE CHANNEL ESC!

Wiring the connectors

Post by modler »

It is going to take me some time to add descriptions to the steps involved here. I am trying to do this in descending order of steps with the pictures which requires some patience. If you have ever posting something like this at this site you know what I mean ;)

I use connectors in all my projects. It makes it easy to debug and check components individually. Plus I may swapp a component out or upgrade and so forth and the connectors make it much easier.

Everything done here requires patience. this can not be rushed. I have many hours in posting topics like this and with something of this intricate nature, I may have to edit out errors so my posts here and elsewhere on this site are continually checked for errors and or added info as I like to be accurate in what I am presenting here. I also use these posts for a reference of my work. Feel free to ask any questions.


Here is a short video of the Panther's first running as a Hobby Grade Radio Control Tank

These are high quality 26 AWG connectors that I now use. I was using ~28 AWG but that is just not enough for these type of applications.

Power supply wires for the ESC and receiver (red\black) which are soldered in parallel are then soldered to the top side of the outer pads on the circuit board. The yellow wires are Aileron\Elevator output wires which go to ESC input  bottom side inner pads. These two connections are the only ones made on bottom side of the ESC circuit board.

Two 1.25mm 26 AWD female connectors for dual motor drive output are soldered to the output side TOP side of ESC CB. This must be done properly as a short circuit here will damage the ESC output circuits. Optional method, Solder one connector to the top left side output Top, Solder the other output to the opposite side Bottom. Less chance of short circuit using that method.<br />ALL WIRES ARE 26 AWD for best performance.

Next step will be to get the wires in position. The wiring has a little extra length and can be molded and bent into final position to allow the upper hull installation

I know those are micro connectors, but they look absolutely huge compared to the ESC! Fascinating work on such a miniscule scale. I struggle with room on 16th from time to time.
