RE: Stuart electronics upgrade for the stock radio

["Flier" <flier-at-sbcglobal.net>]

Dan,

The Stuart has a function in the encoder/decoder chipset that isn't enabled
on the stock radio as far as I can tell.  The stock Stuart system functions
are binary, either on or off, as opposed to a digital proportional R/C
system like you mention.  It would be more difficult and expensive to 'add a
channel' to a stock digital proportional system.  Would be cheaper to buy a
transmitter/receiver with the number of channels you need...

Regards,

Ted

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!


Dan
