OK, the plane ESC was a good first mod, but not having reverse and the fact that the brake kicked in when I would come back to neutral on the TX was giving me the shits. IF you saw the mr02 video I posted not long ago you will see my car (the enzo) kick around the corners in a knee jerk sort of fashion. This was due to the brake issue.

So in the end I upgraded to a real car ESC. But this had it’s challenges. A lot of the micro ESCs on the market are two PCB’s sandwiched together in a (relatively) compact case. The problem here (when it’s decased) is that it has a very “tall” profile making it impossible to fit within the mini-z chassis.

Both the Novak SPY ESC and the AE Micro ESC (comes on the RC18T/B/MT cars) are very tall in their profile and I would of needed to of mounted them high up front which I didn’t want to do.

So I had my eye on the little known Robitronic ESC.

This bugger is small. Only a single PCB size and compact dimensions made this ESC the one for me!

Here are the specs from the Robitronic website.

• Input Voltage: 4 – 8 cells
• Forward, intelligent proportional brake and reverse operation
• “Smart detection” circuit for brake and reverse control
• Pre-wired with micro-style connectors for battery and motor
• Direct soldering tabs for easy rewiring
• Dimensions (of case): 22.7 x 22.5 x 5.9 mm
• Max. Current: 10 Amp
• Weight: 11g

Here it is decased.

It wasn’t hard to attach. I just soldered the 3 wire signal loop from the RX to the ESC and soldered the power and white motor wires as well..

The key here was to orientate it the right way up so I had access to the programming button..

Here’s some more pics showing the detail.


And of course, it’s all in the chassis!

So I’m happy with it. Testing will happen today at betty’s track and we’ll see how she goes….
