Hi kotori,

as far as I know there are at least two more Battle Systems on the market, which maybe interesting ...

The first is the upcoming CSI from [link=http://www.el-mod.de/]ElMod[/link], available in their shop in the next days. Using at least Booster + Prop it will work fine with Standard Hobby Radios.

The second one is my [link=http://rentarasta.de/project/egs/instruction.pdf]EGS[/link] (Electronic Gun/Combat Simulation), available at [link=http://www.imperial-modellbau.de/]Imperial-Modellbau[/link] (Germany). A special interface for Standard Hobby Radios will be available in the near future, but it'll also work with that radios "as is".

Nice weekend,
