Well, for a start the low speed running is far better with the tamiya dmd, speed transitions are far smoother. Also as Ive said before I can do spot turns locking one track with the tamiya where as the rx-18 wont let me. Again this could be down to the shoddy HL controller. Would be interesting to see how this would change with a proper hobby grade radio!
With the 3:1 gears I haven't noticed an appreciable difference in control. Of course I have DBC with HL radio's and DBCRC 2 with hobby radios in all my tanks. I don't think I have one stock HL tank. I suppose the momentum feature on the DBC is what is the contibuting factor to the smooth operation. All in all just goes to show what a great piece of electrical hardware the DBC is.
So probably you are correct. A bare bones RX18 with HL controller is not as sensitive as a Tamiya ESC. However I have got pretty good slow speed performance out of a stock set up, but it does require a very light touch on the sticks. Throw a DBC in and turn on momentum though and the difference will disappear. Remember we are talking about a $25 ESC so I would hope their would be some subtle differences between it and a $150 ESC.
The point of this post was never to compare and RX18 to a Tamiya ESC. It was to demonstrate that an RX 18 can handle the weight of an all metal tank if the gear selection is right.
