RC Tanks Australia Forum

THE first tank board I ever made was the ATRC (Anti-Track Recoil Circuit). A great board, simple, reliable, cheap and easy to make. In fact I posted on other forums way back before this one existed on how to build your own board.

Problem was you needed to solder the 3 connecting wires to pads on the underside of the RX18 and it was here that many users baulked. As a result the Dragon and ultimately the Komodo boards came into existence providing a solder free way of blocking the recoil. These solder free boards used a '-' signal sent by the RX18 to block the recoil and the poor old ATRC which uses a '+' signal to block the recoil got overlooked. That is until now.

For some unknown reason Heng Long have changed all the timings in the fire sequence on the new 2.4gHz boards. No longer does a '-' signal pre-empt the track recoil. The '+' signal is back in fashion. So by plugging and old ATRC into a Komodo cable the ATRC now becomes a solder free means of track removal.

SO now there are two solder free ways to stop the recoil on the new 2.4gHz Heng Long boards

ATRC
and
Komodo+

The main difference is only Komodo+ will allow you to continue to use your high tension flash. So the ATRC will be more suited to airsoft tankers

Above is how to connect up the ATRC to a 2.4gHz board. The 5 pin connector is inserted into the flash port.

NOTE: Many ATRC were shipped with a 10uF capacitor, however, some may of been shipped with a 1uF capacitor. You will need at least a 10uF cap to ensure all of the recoil action is blocked.
