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

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

Thanks Ray.  I've been languishing getting the 
Nieuport done.  I keep finding other things to do 
like RC tanks!  This past weekend I was workin' on 
both.  Spray some epoxy primer on the Nieuport tail 
and work on the tank while it was drying.  Worked 
pretty good.  I had planned to have the Nieuport in 
the air by December --- oh well.  I'm shooting for 
summer now.

I think the Stuart may be just the thing for those 
that wanna get into it without so much building.  It 
seems the electronics are gonna work out good.  We'll 
see.

Regards,

Ted
