Re: Stuart electronics upgrade for the stock radio

[Grauwolf <grauwulf-at-yahoo.com>]

Greetings Ted and All,

Am I reading this correctly? 
Are you, in a sense, adding an extra channel to the Stuart's Rx/Tx
system? Could this upgrade work on other units/controllers such as
upping a 2-ch RC to one that would at least included a firing button???
If that is the case, I for one, would be extremely interested!
