    Mike,

    I really LIKE the characteristics of the controller without a sensitivity pot and, yes, it does act like a resistor controller. Not that there is anything wrong with that! In effect my...

    Mike,

    I disagree. For ME the real advantage of a transistor-based controller is a lighter handle and , perhaps more important, lower currents in the handle for less arcing and pitting on the...

    I am planning on racing in a Nats for the first time since 1990!

    27L and OMO for sure and maybe C12 as well. A lot to do between now and then.

    Jim,

    That would work but it is inelegant. I don't always achieve it but I do like clean, elegant solutions. Not only that but I want to make another controller!

    That is good advice, removing one component at a time and testing the controller makes good sense, thanks.

    The controller is a modified Ruddock DR-40 to which I have added an internal choke. I will be using it to race OMO. I am using the DR-40 you upgraded to race G27L.

    Thanks guys! It looks like a GREAT venue. I am looking forward to trying out the Engleman as well as racing on the King.
