Sorry about my bad english

I have a problem with my summit 1:10 1 generation. This have an old 27 mhz radio, and now am about to oppgrade to a xerun 150amp esc and a leopard engine. But i dont get the esc to work,dont even the fan will work. When i turn it on ,the esc will light green 2 times og the it will stop lightning.And everything becomes dead, But i tryed a ansmann 2,4 ghz 3 channel radio,and it works the first time i connected it. But i want to use the 4 channel radio so i can use the lockers and low/high gearing.

Is there anything i can do so i can use the old 27 mhz radio with the BL ??
