Re: 1/6th RC Stuart drive electronics figured out

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

Sure Gents,

I've posted what I found out on my site.  I 
rearranged a little.  More to come as I make progress.

Joe Sommer has a nice PIC-based mixer which I think 
will work perfectly and alleviate having to have any 
servos or switches.  It may allow direct connection 
of the onboard electronics right to a 6 channel RC 
receiver.  I'm hopin' to con him into burning me a 
couple so I can try it.  It'll be sweet if it works 
and pretty easy to install.  We'll see...

Regards,

Ted
