Of course I will plug the DBC3/Benedini.

The momentum circuit in the DBC3 is really good and it smooths out the RX 18, giving your really good control.
Tamiya compatible, even uses the Tamiya TBU.( Not just half way either, has battle damage, reload delay
Stops the Heng Long recoil and superspin. User selectable.

Very low cost with two sound options

Low cost digital sound card for battle sounds

or go for the full meal deal with the Benedini, your choice

With the Benedini you get programmable sound with some of the smoothest transition sound files in the business. There are a number of DBC3/Benedini systems out there now, so people don't have to take my word on it any longer

One thing I like to stress with this unit is that you don't have to do anything to the Heng long electronics. When you pull this system out you have a fully functioning Heng Long you can resell. Also because you don't touch the Heng long electronics the Heng Long Battle system stays functional as well.
