Roger,
You can get a converter for a KO 2.4ghz Mini-z Module to fit in Futaba or Sanwa radio.
I think the modules are about £70.00 retail and the converters approx £22.00
the price for the Kyosho 2.4ghz Wheel radio is about £70.00.
So if you a stick addict then its worth spending the extra £22.00
Also please note That we are having a Uk Chapionship event at Ardent for Mini-z and Dnano on the 27th of November.
Please pm or e-mail if you are wanting to enter.
